Anybody fitted Bronco retreads especially the 'Grip Edge' tyre,thinking of fitting these all terrain tyres as i don't want to fork out again for Goodrich at about £100 each.
Cheers,

I have a set of grip edges fitted. Replaced my trac edges that were too small when I fitted the lift.

Off road they are pretty damn good.

On road they appear to be wearing quicker than I would expect and are a touch noiser than the trac edges probably due to a softer compond?

For the price I like them.

remoulds used to have a bad reputation, and some people still wont use remoulds.
make sure you check the speed rating as well. afaik, its illegal to use a tyre of lower speed rating than your vehicle is capable of. (except in emergencies, ie space saver spares)

personally i'll be buying remoulds when i next need tyres

I would not put a remoulded tyre on a vehicle that weighs around 2 tons !
They are ok for offroad use and town cars .
Most are not rated for the higher speeds of some 4x4s and can overheat and peel !! :shock:
I have seen several range rovers with cheap retreads on with kids in the back !
Strange that these folk can afford to run a V8 yet wont spend out for proper tyres.
Just my oppinion though. :)

Got to agree with Bullfrog - Tyres are your last line of defence and heavy braking and/or swerving in a 4x4 is bad enough without doing it on remoulds
I would never dream of putting remoulds on a road going 4x4 - especially if I was going to be carrying kids, and in any case they are false economy as their wear rate is horrendous compared to say a BFG or similar
I bet you can go through 3 sets of remoulds for one good set so wheres the saving ?
Don't be tight - buy some decent tyres ! :lol:

if they were unsafe, they wouldnt be sold.
if you wouldnt put remoulds on as they were unsafe, would you put offroad biased tyres on? what i have always done so far is to have 2 sets of tyres
1 offroad set, (so far they have been michelin XCLs) and a set of road tyres.

As Captain Vimes pointed out :

One of the reasons the rich stay rich is that they buy ONE pair of expensive shoes, instead of 5 pairs of cheap shoes that cost more in the long run than the ONE pair of "expensive" shoes.......

In other words, you get what you pay for (mostly) :-)

P.S. My current record is 11 years for a pair of Nikes - and yes I DO wear them, and 15 years for a pair of DM's.......

Fair enough Ian but if you are running remoulds to save money then why buy 2 sets ?
Far cheaper in the long run to buy either a good all terrain or my personal favourite BFG mud terrains which behave very well on and off road for my needs and last forever
Again this is just my humble opinion - each to their own......................

Post by: jjsaul on June 20, 2006, 22:59:57
one of the reason i dont put BFG's (or other expensive tyres) on mine isnt that they last longer...its if you rip one open offroad, a remould costs you £50 , not £120 for a BFG etc!!!!!
so it isnt being tight, its that i couldnt afford to replace it.

and although i havnt personally ripped a tyre yet, i know plenty of friends who have (remoulds and bfg's)

we have grip edges on the 110 and yes they do wear pretty quick but they seem decent tyres.
i have macho's on my RRC and again they wear fast (could be to do with my driving) so i bought a set of G Grabber road tyres as well.
ive just bought a set of bronco grizzly claws for my project but havnt used them yet so i cant comment.

Iv'e just done a quick calculation
My last set of BFGmuds were bought 6 years ago at a cost of £420 which included modular wheels and delivery to my door
They saw me through two 110 V8's and over 48000 miles
I then sold them on for £80 so nett cost to me was £340
Over 312 weeks that works out at less than £1.09 a week - a fair comment ?

I have used the Bronco Roughrider M Tyres on my 90 , its a BFG M T copy - and i rate them highly good in the mud exellent on road and they wear well too, and at 50.00 a corner a real good deal - i dont have a problem with Retreads as they are made to a British standard - and provideing you drive like a 4x4 should be driven with its high centre of gravity shouldnt have a problem on the road,

Unfair calculation. If you didnt use your landy at all you could have sold them 'as new' and got a lot more back.

And also a lot of companies recommend you dont use tyres over 6 yrs old!

...oh and er....really I don't actually own *any* vehicles that could wear re-treads legally.

The only reason the last L322 I had could wear the MT/R's was because they were listed as "optional fitment" in the user manual. Obviously the supercharged one *cannot* run with the same muds :(

As for the speed rating..... in one of the "many" previous posts on the subject.... someone pointed me to the fact that the speed rating must be to the legal road speed limit..... not the top speed of the vehicle.
I'll do a search for the legal write up on it..........

Here we go......

REGULATION 25 :
This Regulation is concerned with the tyres load index and speed ratings. It specifically deals with, items such as the tyres fitted to Goods Vehicles, Buses and Trailers and for which a Ministry Plating Certificate must have been issued, and a Ministry Plate attached to the vehicle. Amongst other vehicle information the Plate, which must be securely attached to the vehicle in a conspicuous location, gives the maximum axle and gross vehicle operating weights. The Regulation requires that the tyres fitted to the vehicle are not only capable of supporting the maximum permitted load on each axle but of doing so at the vehicle’s maximum legal speed. In defining “load–capacity index” and “speed category” the Regulation makes reference to UN ECE Regulations 30 and 54 and to the European Union Directive 92/23/EEC.

You'll notice 3rd line up..... "vehicle's maximum LEGAL speed".

remould tyres have to pass safety tests, and speed ratings.
remould tyres are available for sports vehicles.
colway make a full range of 'rally' remould tyres(that sporty enough for ya?)
remould tyres are available for sports motorbikes.
the majority of heavy goods tyres in UK are remoulded
the majority of bus/coach tyres in UK are remoulded
aircraft(jet) tyres are remoulded
remoulding tyres is the 'green' option
remoulded tyre carcasses are fully inspected before remoulding
Personally Ive got 20k miles from a set of colway MT's, before discarding(still with about 5mm tread but now not so good off road)

I feel happy with remoulds, if its a personal choice, then OK, but if its safety/wear/speed/environment, then Id say go remould......

I ran colway m/ts on my frontera for 3 years.. same set, little wear, good ride and quiet... with my 3 kids in the car.. never a problem.
Recently got machos on the disco... really great off road and not bad on road but already noticing signs of wear... £50 each... time will tell if its a case of false economy or not....

Post by: Henry Webster on June 21, 2006, 13:15:59
I agree largely with Rollazuki!

I use 205R16 Kingpin Highlander Diamonds on the racer and think nothing of doing 100+ on them on gravel tracks.   They don't last long (2-3 events in common with most rally tyres!), but they are fantastic at the job.

I also use Goodyear MT/R 225/75/16 on the racer.  These have lasted much longer and are more stable in the fast stuff, but don't have the same levels of traction when it gets sticky!

On my road car I choose to use first life casings - i.e. new tyres, this is purely down to economics.  I reckon I get much more life out of new tyres than I would out of remoulds.

I would have no problems running on remoulds on the road, but choose not to other than on the racer.  It is, however, fair to say that the quality of remoulds does vary, even within one type of tyre in the manufacturers range.  Wherever possible I try to pick the tyres from a selelction when I buy remoulds.  That way I have some control on the casings used.

Cheers

...so it's down to the load rating then - and that *IS* the biggy. This would explain why I was told that my MT's on Owl were load rated.....and no mention of speed rating was made.....

For example - if we were unlimted - 3 tons of RR at 170mph would have a serious issue if the tyres were not LOAD rated.....ON AN AUTOBAHN.

So....er.....get's confusing eh? Your remoulds are legal in the UK on sealed roads, but illegal elsewhere?

I have to agree, if I was driving something with nigh on supercar performance Id mebbe think twice, but I think for the average suv driver who also drives off-road, they are a safe, economical, and green option.
As fossil fuels run out, we may find that new tyres become prohibitively expensive, and recycling tyres will become the norm. I dont know what you are going on about anyway thrasher, Im sure your rangie sport nutter thingy would be fine on a set of SAT remould mudders..... :lol:

I also have on my other car which i run back and forwards to work 600 miles per week thay have done 20K I have had no issues with them

But if it was high performance then the best tyres money can buy

i reallity, could any of acually tell if a tyre is remoulded or not (ifn it had no markings on the tyre of course).
they look the same, they drive the same, they last as long.
like one of the other posts said neally all truck tyres are re moulds, and if its good enough for 40 tonners then its good enough for my old truck.

Post by: bullfrog on June 21, 2006, 22:28:33
My point would be the influx in the 4x4 market of new brands of remoulds that may be inferior in quility.
For offroad use yes but not at 70 odd mph.
I think you will find that 90% of retreads are speed rated to less that the average modern landy .
I thought most truck tyres were recut not retread ??
I still find it strange rading peoples list of mods that most have expensive snorkels, Lift kits and such yet skrimp on the most safety critical component ??
Just my opinion though. :?

Found this thread looking for grip edge reviews.

But feel I have to say work provided me boots for free, they have survived glass bottles, barbed wire and petrol bombs. I've had them for probably 9 years now and wear them daily. Laces don't like petrol bombs mind.

Any one actually got any feedback on the grip edge?

I don't like remoulds.

Yes I know,it's a prejudice but I think that remoulds are tyres living on borrowed time.

In their defence, recyling is good, remoulds are very green.

My Machos were btter off-road than my BFG MT, or is that just my memory playing tricks?

Amazons have a better speed-rating than BFG MT anyway, important for a V8.

Downside, remoulds are often inconsistant, you don't know what's underneath so how can you get 2 the same?

Apparently many are bullt onto truck tyres so the sidewalls are stiffer (truck tyres are better for long life).

Then the whole qualty issure of sticking a new tread onto a tyre that's lived a full life, which sees the rubber it's made from harden with the constant heating/cooling that tyres suffer.

You pays your money..........

Post by: Eeyore on March 23, 2007, 08:33:37
Just to point out, the legislation mentioned above only applies to goods vehicles and their trailers, it seemingly doens't apply to passenger vehilces.

According a number of our tyre fitting franchisers, what does apply to passenger vehicles is that you can fit any speed rating you like, as long as you don't exceed the speed rating of the tyre when on the road. Now, whether your insurance company likes this is a different story altogether and you may find your company invalidates your insurance if you use a tyre with a lower speed rating than they'd like (no joking here).

Second point, airplane and truck tyres have very rigid carcasses and are designed from the out to be remoulded. Car tyres aren't. Car tyres are designed to have a finite life and you have no idea as to how old the carcass you have is. Yes, there is legislation, but as pointed out above, some folk are quite unscrupulous with their application of legislation (like a well known case where a company was illegally e-marking there tyres!).

Did you know some 4x4 remoulds are made from commercial vehicle carcasses? That has a significant impact on handling......

Yes, remoulds can be very good, but a first life tyre will be built to a more traceable standard.

Buy Wolfie a ginger beer and ask him about the conversation he had with the chief designer of Dunlop.  :wink:

Personally, my BFGs have clocked up 70,000 miles and are still going strong (if on the limit for lifespan). I haven't ripped side wall out although I've peeled off the rims a few times! I will be buying the same again. Some things (IMO) just ain't worth skimping on.   :wink:

We race on first-life tyres too, and not just because we got 'em at a discount (which, thank you Matador, did take the sting out a fair bit!).

You do pays your money and you do takes your choice, but be aware of all the facts before commiting your hard-earned.

Colway do have a good reputation, other manufacturers don't.

Anyone for a lottery?  :lol:

Food for thought

And they are able to do so!
So if you're using (for example) 'L' rated Simex (if they're rated that highly?) on your bob-tailed Rangie, or V8 90 & have a RTA, the insurer can dispute payment to you - as it can do more than the speed rating of the tyre.
They would probably pay the third party, but try & claim it back from you?

From speaking to Traffic Officers at work (who come to interview RTA victims) they, or the Accident Investigators, do look at the tyre speed ratings.
Okay.... I know that it's unlikely that probably 99% of what the incidents they investigate will be in no way related to a non speed-rated tyre, but as they say; 'Ignorance of the law is no defence'

The BFG A/T's on my 110 have done almost 57,000miles & are (I think?) the original fitment, & they have roughly 4 - 5mm left.

My first 110 had the original Avon Rangemasters on when I bought it at 47,000miles.
They were a bit more than half-worn, but still worked extremely well in all situations; bar Clay.
I replaced them with a set of Bronco M/T's (the BFG M/T replica)
They covered almost 30,000miles in my company & were excellent on all surfaces; from 70MPH on Welsh mountain roads (around Sweet Lamb, Llanberis, etc...), towing, commuting, mud, etc...
The only place they let me down was on Pendine Sands :oops: , as I got bogged in soft sand with the tide coming in :(scared):  (but a bit of rocking with dif-lock engaged got us out)


When the BFG's wear out, I'll probably look at the Bronco 'Grip-Edge', unless I can find a set of Trac-Edges that have lived a secluded & dark life on the back of a tyre-depots shelves

After consideration, and a nice telephone call (not many supliers would do that) from Mark Sowden, I've ordered 5 Macho's..... (from him at www.sowdentyres.co.uk) need to get the alloys refurbed now!

I think it's been mentioned before somewhere, people buy from people! I've just proven that, I tried to buy some locally yesterday and no one could be bothered to get off their arse to get me a price! may be because I wasn't buying BFG's @ £100 + Per Corner, still they've lost £255 of my cash!

Mark said that a customer of his has done 48k on a pair of Machos mounted on the front axle of a 4x4! I know several people with them, seems good enough to me.

Report prepared by
S.A.**********– HND, ONC.






INTRODUCTION

I am currently employed by ‘Starco’ Europe, which is part of the ‘Scandinavian Tyre and Rim Company’, as Technical Director.  In addition to my responsibility for technical matters in the UK, my role extends to technical support for all 13 plants around Europe and Russia. The Company manufactures wheels, tyres and wheel assemblies for supply as Original Equipment to vehicle manufacturers.  Previously, Goodyear had employed me for fifteen years until May 2000.  My final position as Technical Training Manager, gave me responsibility for all Technical Training of company personnel operating throughout the UK, Europe and the Middle East. Prior to this position I was Manager of Product Performance and Service department for six years until 31st December 1994.  In this role I had occasion to examine many thousands of tyres having failed either in service, or as a result of systematic destructive testing.

I began my career with British Leyland as an apprentice and gained extensive experience in all aspects of automotive engineering in both design and practical skills. I hold an HND qualification in Mechanical Engineering and an ONC in Electronics.  Following my apprenticeship I worked for 11 years in research and development, specifically dealing with axles, brakes and suspension systems as part of a vehicle design team.  I specialise in all aspects of vehicle design and behaviour, and in particular, tyres, their performance, and the interaction between tyres and vehicle suspension design.

I have been asked to examine the subject tyre(s) with the purpose of identifying the reasons for their current condition, the nature of any structural failure and any possible implications to the merchantable and safe condition for sale.  I was given the information that the wheels and tyres were fitted to a ‘Landrover Discovery’ 4 x 4 vehicle and had only travelled for a relatively short distance since they were supplied.

THE TYRE(S)

I examined 4off wheel and tyre assemblies at a private address in********, at the request of Mr ***********of Leicester Trading Standards, the details of which were as follows:

Tyre size: LT 265/75R16    
Service description: 112Q
Brand: ‘Bronco’ Grizzly Claw
TDR: 14mm centre-line – 17mm at shoulder
Production date / Serial No: No markings

Other markings:   Retread made in England – conforms to BSAU 144


EXAMINATION

Following a careful examination of the wheels and tyres, the following details were noted:

Wheel Assembly No. 1

 The first of four tyres was examined having been fitted to the front of the vehicle, to reveal a structural failure in the shoulder area of the tyre such that complete and catastrophic deflation had occurred.

There was clear evidence of rubber degradation and cracking due to overheating and rubber reversion at the base of the large shoulder blocks and also at the junction between these blocks and the carcass where there are naturally uneven stresses due to the heavy lug design.  
The carcass showed clear signs of distress at these same points and had suffered separation between radial cords and also belt edge, resulting in structural failure.  The carcass had suffered from severe abrasion and overheating in the shoulder areas as was evidenced by the inner liner condition.  I was unable to detect any evidence of a penetration which might have caused the deflation.  The deflation appears to have been caused by the break-up of the tyre structure, the evidence of overheating being such that it had occurred over a relatively short distance including the time taken for the driver to pull over and stop when it was realised that the tyre had failed.

Wheel Assembly No. 2

The second tyre, also having been fitted to the front of the vehicle, was also showing similar signs of rubber reversion in the shoulder blocks with some cracks beginning to appear.  However, this tyre remained intact insofar as it was still inflated and no major structural failure was immediately apparent.

Wheel Assembly No’s 3 & 4

These two tyres remained in apparently sound and inflated condition.

Balance Weights

The following quantities of balance weights were seen to be fitted to the wheel assemblies, having been balanced by the tyre shop who supplied the new wheels and tyres;

Wheel assembly #1 – 225 grams
Wheel assembly #2 – 200 grams
Wheel assembly #3 – 190 grams
Wheel assembly #4 – 100 grams


TERMS OF REFERENCE

There are standards laid down within European Directives ECE108 / ECE109 regarding the manufacture and testing of such remoulded tyres.

These performance requirements are specifically to ensure that process quality is consistent to the original development of the remoulded product, and that any such product is capable of being operated within the performance suggested by its service description.

The markings ‘conforms to BSAU 144’ are out-dated and obsolete for two reasons (i) They are now superseded by ECE 108 / 109, & (ii) In any event, there were several suffix additions and revisions to BSAU 144 even when it was current, no such suffix is marked on these tyres, this means that these markings were insufficient even when last BSAU 144 was current.

The remoulding processor is totally responsible for ensuring that the carcasses gleaned from tyres having previously worn-out treads, are in suitable condition for both the re-moulding process and the subsequent safe operation with the new re-moulded tread. A further requirement is dynamometer testing (sometimes referred to as ‘drum’ testing) for the required duration to prove that the tyre tread design, rubber compounds used and re-manufacturing process are all of such integrity that they are safe for continuous operational use up to the full load and speeds indicated by that service description.

The above mentioned dynamometer tests are required to be repeated during production runs to ensure that each subsequent batch also complies with the same requirements.
 
CONCLUSIONS

The tyres fitted to the front axle of the vehicle whilst it was lightly loaded (as was the case according to Mr******), would be subjected to a higher load than those on the rear axle due to the un-laden weight distribution of the vehicle, additionally, the steering forces would also load the shoulder areas of the tyres more than those at the rear.  This is therefore a fair indication that the loads at the front axle, although being far below what the tyres are able to carry according to their service description, creates the differing results.  Both front tyres were showing signs of distress, with one of them having failed completely, both rear tyres being in better condition than the front ones.  

The two front tyres showed clear evidence of overheating and rubber reversion in the shoulder areas and as the tyres were not carrying their maximum load, this tends to indicate a small safety margin with regard to heat generation and satisfactory running temperature.  

Mr *******informed me that he had operated these tyres in the same way as on previous sets of tyres and at the same correct recommended pressures for the vehicle, and I am unable to detect any collaborative evidence for under-inflation prior to the complete deflation of the tyre due to the carcass break-up.  

The quantity of balance weights fitted would give concern regarding the uniformity of the re-moulded tyres; generally, re-moulded tyres have very good uniformity as the action of buffing off the worn-out tread tends to reduce any run-out within the original carcass.  It is interesting also to note that the worst offender in this regard, was in fact the same tyre on the front of the vehicle which had failed.

It would be a matter for further investigation as to whether the remoulding manufacturer has in fact dynamometer tested the original remould design and/or the subsequent production batches, to prove the ability of the tyres to be operated safely at the rated load and speed in accordance with ECE 108 / 109.  

These tyres do not carry the required markings to indicate that they comply with the required testing procedures for the above mentioned standards.

It is therefore my considered opinion that these tyres do not comply with the necessary regulations, governing the sale of such tyres for use on the public highway.

You know, within ten days of first readin' that, I found three other folk within 5 miles of my location who recently had new Slippery Paws delaminate on them. One at speed.

Like I said, you pays yours money, you takes your choice.......

Makes you wonder

Well I have Colway remounds all round - 245/70R16

These have a speed rating of 99mph which is faster than my Disco will go so no worries there. The only thing that has happened to me is that one blew out if that makes sense between the tread pattern. I didn't run over anything, it just went bang when I was driving along and on closer inspection, there was a flap like hole.

I think you can't go wrong for the money, its true you get what you pay for, my last disco had Pirelli Scorpian ST's that were brill but this Disco is on a tight budget so Colway it was - £49 per tyre inc VAT ain't bad at all :wink:

i run on colway AT's and absolutely love them- great on and off road. the reason i switched to them though was because i needed to get the main brand tyres off as they had just nearly killed me again by locking up in the wet. Saying that though i wouldn't put remoulds on the 170 mph+ bike (on track days only)! true that you have to make a choice but i've taken colways right down to the death and they havent fallen appart on me yet.

We have Colway A/Ts on the series 3. IMHO they're fine for a 4X4 that does 60mph at a push and spends most of it's time waiting to be fixed anyway...  :lol:  :lol:

I had a set of Grizzly Claws....Great for off-road but absoulutely sh*te on road. Unstable,loud,prone to changing direction of their own accord, started to break up after 1500ish miles. And I don't think they're over cheap either?
Now running a set of BFG muds......They're stunning and super quiet even at 70mph on a concrete motorway with the windows down. £100 each fitted 'n' balanced (265/75's) I can live with that.

And as for wagons running remoulds.........How many disintergrated tyres do you see on the motorways ??? :shock:  But I suppose it's not too bad when you've got another 17 underneath your vehicle :wink:

Truck and plane tyres are made to be re-cut/moulded. 4x4 tyres are not . Brands such as colway have been around a while and seem to have a good reputation but "other" brands are dodgy european carcasses that "may" have a history.
You can also tell a lot of remoulds by their poor mould and lumpy side walls.
I have remoulds on the site vehicle as it only goes 10mph max but I run branded on the road vehicle.
Just my oppinion though and folks are free to make their own choices (I think) :?

I have BFGoodrich MT which are supurb on and off road. I also have used them for miloes and miles.

As for all this "tearing them offroad crap", how many tyres have people actually done like that.

Chalk, flint, stone. I have not. I dont think i have ever known anyone tear open a BFGoodrich. I know of one Bronco that tore open!

Remoulds should be about £25, they are reused three times and only require new tyre treads.

Not for me.

I have just changed my grizzly claws for pro-comps as i wanted 35's. The disco runs so much better, handling and quicker acceleration (even with the extra 3" diameter). The main problem i had with the Broncos is that they peel around the bead. Spoke to Bronco and they said it was normal just cut it off with a knife!!! When the bead peels away small bits of muck can push down in giving a poor seal, hence th last time i drove on them i pulled two off the rim.

I have just ordered a new set of Colways for my Terrano II from Snowden Tyres. I also had them on my Grand Vitara and was very impressed, never had a problem with them and they were as cheap as chips.

If the tyre is new I would contact the manufactures and see what they have to say, Colway apparently are great and you'll get a new tyre no questions, however I have never had a problem so wouldn't know.

Got 33x12.5 Grizzley Claws on my tank,

They are great off road, but on road they are horrible! As said in a previous post, they change direction badly (obviously following cambers) and are soooooooooo noisey, at less than 30mph it sounds like im being follwed by WW2 fighter plane! Have got another set of road tyres to put on for normal use, cant wait to swap them over

Cheers

I used my Machos on the road and TBH they were a bit noisey but the handling was ok, even though one of them didn't look that round.  Now that I can afford it I run BFG A/T or M/T and I'm much happier, especially when towing.

Interesting topic.

I rang my insurers (Adrian flux) about fitting insa turbo special tracks to my v8 disco. I clearly stated that they were Q rated (99mph) and that the top speed of my jeep was higher (106mph) but i stated that with the speed limit being 70mph max it didn't matter.
They checked and double checked and said its fine to run them but im just waiting for it in writing off them before i do anything else.

On a slightly different note, i said i wanted to add a snorkel,lift the suspension, fit arches and bigger wheels and tyres and they said there would be no change to my premium - how good is that?!?!?
