35inch tyres on a 300TDi?

--- Quote from: "beatmasterdave" ---hi all, found a place to modify my standard disco for £1950 all in, for
4 X 35"1250 r15 Procomp Muds
4 X 8x15 Steel wheels
Suspension (springs & + 5" shocks/ spring relocators)
TUV Approved Prospacers
Devon 4x4 Extended wheel arches
Brake line mods
All fitting & testing
is this reasonable? so far i think its really good, being fitted by people who have done it before. aparently the gearing will be fine too! :D :D :D 8) 8) :P :P :P 8) :D 8) :D 8) :P

i will try to comment on this sensibly..
you are planning a huge transformation to your disco....
you also seem to want to make it an extremelly succesfull off roader.
fitting 35" will take you further throught the ruts than others...
but to put 35" tyres on your disco you are going to spend a lot of money and time...
spend the time researching and not impulse buying and your vehicle will evolve well..
good luck with your venture

Budgie:
If you go ahead and fit the 35's without altering the gearing then you'll be slipping the clutch just to pull away, at 30mph you'll be in 3rd and if your lucky you'll get into 5th at around 45mph. Any slower and the engine will labour.
When you see a hill, you better put your foot down cos' you'll be in 3rd, maybe even 2nd by the top with a head wind, and I'm talking hills on the M6 here!!
A couple of other things missing off the list are:
New front prop, maybe the rear one as well. The standard props will have problems operating at the angles a +5" lift will produce. I'm assuming that the spring are also +5", if they are only +2" or +3" then you'll need a body lift as well. And I don't want to go into what the body roll will be like with a +5" suspension lift because of the increased CofG.
Steering correction. Front radius arms will need to be longer and set so they correct the caster angle otherwise you will have a job keeping the Disco in a straight line on the road.
The rear trailing arms will also be too short and will pull the axle forwards.
Anti rollbars will have to be removed, unless you can find 5" spacers to put under them.
Your bump stops will need extending to stop the tyres impacting the inner wheelarches on full articulation.
I'd also question putting 35x12.5's onto 8x15 wheels, 10x15's would be safer. You could save on the price of the Prospacers by getting correctly offset wheels as well. Buy the time you've payed for the new wheels and the spacers then you're only about £10-£20 per corner short of a set of Matt Lee' wheels made with the offset you want. :wink:
Do some searching on here and read up on some of the older posts about this subject before you part with your money.
Myself and the others who have posted above are warning you for a reason, most of us have made the mistakes and learned from them. We're just trying to make you aware of what you're getting into before you spend any money.
Read through what we've said and make a list of questions, then go back to these guys and ask. :wink:

Good advice Budgie, i was in a rush last night to go playing int he snow...we had bonnet deep drifts in Derbyshore last night!
Im not sure and im not bragging but i think i was the firs ton the forum runnign 35's and 3 link(correct me if im wrong) I have had the tyres on for a very long time and went through several suspension designs and set ups.
I have through much trial and error got to the point i have a useable, very flexible(2nd at the Kirton Scorpion challenge ramp off last year against some of the top challenge truck in the country) and extremely capable truck.
Its up to you but noone on here will gain financially from telling you porkies....just bear that in mind.
Propshafts definately become a problem and to get enough clearance for a flexible set up you need to have at least 4 inch.
If Matt is still up and running(he was considering sellign up to concentrate on racers) get some big offset wheels and they will also look much better than mine, DAMN!
Just take your time unless you have a wish to blow money for nothing. Why not let your truck evolve a little ,we all did.
You going to the Donington show?? You should as there will eb loads of advice available!

Hi im runing Insa turbo special track approx 33" on modulars
to do this i have +5 shocks, +2 springs, +1 spacers. extended turrets bump stops and brake lines. also a rear A-frame spacer, corrected radious and trailing arms
around 3+ cut out of bodywork and flair's fitted, drives fine with minimal roll, its a bit sluggish on pullaway but its a 300tdi so thats normal. does about 70 easy but 5th gear is optional..
i would love to fit 35" but dont think its worth all the extra cost.
and my tyres are only about £60 a corner, it works rather well though
