Some times you can't help but be on a side slope, I've had it before on a failed hill climb where the range rover ended up slid round :(scared): and other times where the lane just banks and there is no option but to be on an angle or reverse back the way you came.

Widening the vehicles track is important to maintain stability (and turning circle) with bigger tyres. Another reason for fitting different axles is that some have a much wider track as standard than LR axles, plus you can overcome all the strength issues.

Can't get my head around why anyone would want to put 38's on a discovery.

It will certainly ruin any sort of road performance the vehicle might have had and as for off road use the articulation would be extremely limited. To counter that and give any sort of usability in cross axle situations both diffs would need lockers as well.

Not a practical solution at all fitting 38's. Even 35's will cause similar problems as mentioned if many other parts of the running gear and transmission are not properly sorted. Most who fit these big wheels will have you believe it all works fine . . . but some of us know the truth . . . . we've already been there . . . .

All I can say is that it is really only for the looks and personally I think it would look out of proportion and a bit silly.

A well sorted truck like Budgies on sensible running gear should out perform a truck on 38's any day of the week. As for the gas tanks . . . that's just an excuse, there's loads of alternatives . . . . and I know plenty who run them under the chassis without any problems whatsoever. By your own admission you said the extreme stuff was out because you want to drive the truck home . . . . so whats the problem?

Here's mine on 33/12.5's and a sensible lift . . . . this truck articulates very nicely, has the necessary suspension/transmission mods and performs impeccably on the road.



All down to a bit of fore-thought and porperly sorting the bits needed to make it all hang together.

The Disco is NOT the vehicle to be undertaking the mods you will need to do make it all work, I'd have a serious think about it and talk to those who have been there and done it . . . . as was suggested earlier, you are in hybrid territory and well sorted ones do not come cheap  :wink:

must say i have way more travel than you and mine has 35's. you are right it isnt easy to achieve but can be done. I have just spent a week in Kirton helping set up the Euro challenge and drove there and home at between 60 and 70 with no issues(other then horrendous fuel economy!!).

AS for hybrids costing a fortune only if you are stupid enough to buy someone elses bodge!! ive seen some right crates.
If i wanted a hybrid i wouldnt pay someone for their 'practice' build!!

At the euro challenge one of the guys was using his freshly bought truck,it was very nice but for 17k or so it should be...i could build better for a lot less.

If he wants to fit 38's why shouldnt he? its his truck and im all for people stretching what has been done b4. but fo rspeed trials it will be pig slow on stock gearing!! as rolla says 4.7 diffs would be best but would blow up very easy best to go for 4.75 from Cam as they do the ring and pinion :wink:

Hi Bulli.

Yeah mate I know your truck, one of the best sorted around, respect mate . . . .

and I'm not saying 35's don't work in a Disco . . . I know they do . . . . will probably end up in mine as well when the 33's wear out  :wink:


BTW . . . I'm seriously looking at 3-link for the future . . . . that should get things flexing a bit more.


Oh . . . and in that pic the suspension is not on the limits  :lol:

i wouldnt fit 33 /12.5/16 fit 285/75/16 there be better believe me.

i going 35/10.5/16 and 6inch lift minium . for the sake of big wheel converison you r better of going for it than holding back.

my mate used to have 265 on but now has 36s and 5 inch lift.

and never looked back.

as for 3 link at 1500 quid noway it simply wouldnt need it . trailer maybe but for the road the handling would be none control able.

you think, what so 70 perfectly smooth no pulling from steering isnt controlable??? how fast you think your 3.5 will go with 35's??

on stock gearing it probably wont pull 70....i know i have the same engine with freeflow exhaust and k+n/ safari snorkel.

why 16's and why narrow?

get some 15 inch rims and sort the offset...ps 35's fit with a 2inch lift!! 6 inch why???...yours will roll worse than mine lol!!

mine has a properly sorted 4 inch lift to give me the upward travel i need and i still need to raise my top mounts another 2 inch...

ps all tyres are not equal fit those crappy tyres and you put your life and others on the line if you do ever get to 70...!!!

where are you from?

speed rating on 35s with 20mm of tread is normally 68mph with 14mm its 87mph.

i remember going down the motorway with 235/70/16 grizzly claw on and holding compared to macho was poor. that was doing 70mph like you said

with macho u hit the balance of grip in the mud and road holding apart from braking of course.

im always going to fit 18mm of tread tyre cause they get the job done so much easier than say bfg m/t. the main reason being the sidewall.

my truck is only used with mud tyres for a weekend hence there no need to rush.

the main reason why i wouldnt use 33/12.5/15 is

poorer turning

wheel skimmer

oversized rim causeing bearing wear quicker

on a 2lift they to fat compared to 285/75/16
which makes archs a problem for catching

more heavier and sinks in soft ground.

with 3 link is get off road but it height what stop me than grip at the wheel alot of the time. plus never one for rock clawling.

are wheel arch flares worth the money?

Well I can say that my turning circle is about the same as your is now with my 33" tyres because I've got spacers fitted. Some others have gone 10x15 wheels with the greater offset to retain the turning circle.
With 38" tyres then your turning circle will be even more reduced than what it would be with 33's.
You'll also need some sort of wheelarch flares for the vehicle to remain legal on the road as they have to cover the tyres by law.

As for the wheel bearings, if you think 33" tyres are going to be a problem that what do think 38" is going to do, they're the same width but you'll need a larger offset and the running dia' is much greater?
In the 4 years I've had the 33's on the Disco I've had one set of bearings go, and that was the near side front which started rumbling on Saturday this week!!  :wink:
As long as you keep them tight and well greased then you shouldn't have any problems.

they would be fitted to 16x8 steel rims . its 10.5 wide im really looking for but it is early days .

with enough lift on the body 12.5 will be legal for the law.

12.5 for the fat look i really like

they do them upto 14.5 wide.

im running 265 and was going to fit 32/11.5/16 but couldnt find the tyres i wanted.

right so there you go contradicting yourself???lol so you dont want wide tyres because they weigh more and so sink?? have you EVER driven with wide tyres? Have you ever been offroad?

Anyway go on fella maybe 10 inch lift and 40's is what you need. Just remember that your engine will struggle to make 40 on the road and break the diffs/halfshafts/cvs every time you sneeze.....

Tyre speed rating is nothing to do with tread depth...where did you get that idea??
The Performance Symbol indicates the maximum speed at which the tyre can carry it's maximum load.

The performance symbol of tyres are as follows:

Q : 99 mph,
R : 106 mph
S : 112 mph
T : 118 mph
H : 131 mph
VR : > 131 mph
V : 149 mph
ZR : > 149 mph.
W : 168 mph
Y : 186 mph

mine are rated as Q which is legal as the spec for my 3.5 says it will do 98 mph lol...but i think you will find most MTS are illegal for road use.

oh and its rock CRAWLING.

Designed in Durham alongside the Colway range, Greenway tyres satisfy the requirements of 4 x 4 competition racing or simply extreme 4 x 4 off road. Specifically designed to cope with such activity, the tyres are able to cope with extreme amounts of mud, meaning nothing can stand in the way of you and your off road adventure! Greenway tyres are a must for anybody seriously considering 4 x 4 competitions.

this type of tyre i meant had a speed rating of 68mph

Capable of operating in extreme, hostile conditions, with excellent self-cleaning capabilities and a scalloped shoulder system.

this one has a speed rating of 87 mph.

wide tyres are better for floatation i.e on sand. narrow tyres are better for deep mud.

10.5 is ideal and used for most comp. discos.but they are not available yet in plus 35s . to what i have found.

so if i wrote a load of advertising blurp that would make it right?

most articles in magazines use extracts from the manufacturer and are in some way biased...sorry guys in the trade(you know who you are).

so they are illegal on your truck then....great! hope you dont have an accident and find yourself without insurnace.

So build it, go on im waiting....  :roll:

do u remember reading the ice landic range rover on 38/14.5/16 orange g4 lookalike 1 in lre aug 2006 think that was 3.5 v8i producing 125 bhp if i remember right.

come to think of it there was a tdi disco with 38/15.5/16 , i have to add mite that one was done wrong in my eye. think it all had to with the rear axle being moved back 6 inch wheel base of a 106 inch mmm. hows that going to help with ramp break over?. as for using it being so wide mmmm .could do with a lot of room to offroad in.

if you put tyres on your car which are rated for a lower speed than the manufacturer says its capable of it is illegal.

That means that your insurance could be invalid in the event of a crash...not fun.

the 3.5v8i makes 185bhp according to parkers....

you still have trouble. I have 4.1 ratio diffs in mine with tiny 35's and it doesnt want to pull on the motorway.... so 38's is quite an increase in rolling radius.

The icelandic one may have had changed ratios in the diff....its either that or transfer case...but that only alters high box ratios. 4.1 only corrects to stock gearing with 31's....

Steve

Just a thought, if I'm reading this right the big tyres will only be used off road, and you will therefore presumably revert to a more normal sized tyre for normal driving?

Is that right?

Not if they stick out beyond the width of the body they won't.
You can have the vehicle as high as you want but the tyres still have to remain inside the width of the body.
That's why I, and others, have gone for the wheelarch flares. They allow the fitting of wider tyres or a wider track but they still cover the tyres and remain within the law.

You may well find that you'll get a larger choise of tyre size if you also look at the 15" instead of trying to stick with 16's.  :wink:

the 3.5l v8 produced different bhp over the year i ll try to get this right

1970 range rover 130 bhp

mid 1970 range rover 125- 127 bhp

stage one v8 series 3 had 91 bhp

last 2 door range rover had 135 bhp

11o and 90 pre 87 had 114 bhp

11o and 90 after 87 had had 135bhp

early disco had 145 bhp.

with injection you get

165 bhp on all range rovers with 3.5 l v8i

disco with a cat had 153 bhp

disco pre cat had 165 bhp.

as for the sd1 35oo p5b rover cars and the rest i dont know
