Thread: 35 inch tyres.

lol, yes 33's or 35's on a disco is a big expensive operation

Almost everything said has to be done even to fit and run 33"s.............

Standard tyres I think are 225/75R16 which works out to approx 29"

I just went from 33" muddies to 35" BFG All Terrains - and it drives about the same, if not better on road. I run 4.11 ratios through auto tdi. The 33"s were 285 (11.5" wide), no rubbing even at full lock, on -25 offset steelies. The 35"s are 315 (12.5" wide) and just rub the radius arms on full lock.

Standard brakes are somewhere between terrible and dangerous, and that is brand new discs and pads. Although it is due for new fluid and bleed.

I have been told that you can only engineer 33's not 35's, but I have not looked into it. Like said, you don't have to get it engineered, until something goes wrong............

BTW, a disco with 32" simexs will out drive a 33 or 35" AT or Mud tyre, unless getting hung up on diffs, so if you are going simex style tyres you might not need as big a size as you think. But it will be terrible on road, so will need 2 sets of tyres if its a daily driver not a pig.

Also after going to big tyres then you will also want to spend more on engine etc to get back some performance.......... Many more $$$.

Do a complete costing before starting anything, plan exactly what you want the disco to become.

Costs a truck load to run the 35's but how sweet is it cruising up those tracks. With the lift required and the wider footprint they are so stable and comfortable to drive. I contemplated going down to 32's because of the legalities but I love driving my disco with the 35's and reckon I will even more once I get my new diff locks and gears in. So there is buckleys chance of me going back

somewhere to hang the spare as it wont fit on the rear door


Just do what I did take off the rear bar cut a section out under where the wheel hangs and weld in a plate. Bingo 35" hanging off the back of my disco no problem and it looks awesome

seriously do research on it before you buy them as you may be making an expensive mistake - but if you do it right and get it engineered then it will be near unstopable

Everyone talks about upgrading the brakes, Blitz here states to go to RR vented rotors, is this just a rotor replacement or do I need to replace the calipers also?
Is another option to just change calipers to ones with larger pistons and if so which RR/Disco's/Defenders had the larger calipers?

Apologies if I am hijacking this thread however I believe that this is a major factor when considering an increase in tyre size.

Love this forum

Definitely not hijacking as it is all related to the same topic

The reason why I said RR conversion was because it made so much difference to mine, which could have been because mine were so stuffed a piece of cheese in there would have made an improvement

They are basically the same except vented instead of solid so naf all fade, a spacer is fitted in the standard calipers so that the wider vented ones can fit. Had I know about this and was 100% sure it was correct that is what I would have done to mine instead of the RR conversion. The main reason why I did that was because I put a RR 4.6 in her and thought it would keep Mr plod happier. (and because I needed a boat anchor to help it stop)

i believe the defender calipers have a larger piston and can be fitted - someone on here with more knowledge will either say yes or tell me I'm full of it. I have also been told that braided brake lines help as then there is zero expansion of the line as the brakes are used but again not 100% sure if this is correct or not.

Just fitted new diffs to my D1 with 4.75 gears and lockers it has acceleration again with the 35's. Can't wait to test them off road :-)

Yes indeed, 4.1 are too low for 35's, goes ok but it misses the extra revs on hills....

100kmh its about right on 1500rpm, not too much power there when you hit a hill, or a headwind for that matter (300tdi)

Might look for a set of 33 AT's, better for the 4.1's........

Correct, defender calipers are the go, huuuuuge improvement
