Thread: 33inch tyres on a D1

you will most certainly be at more risk of damaging a diff or axle with larger tyres, i broke a diff with 235/85's (just under 32") and many other people have done similar, don't let it stop you from putting the tyres on, just be aware that rover drivelines are not overly strong, and eventually you might need to replace something

I have run 32's and 33's on my disco for a long time and I'm still on the original diffs itallcome down to how you drive and I don't go easy by any stretch of the imagination

Is anyone running 255/85's on a 0 offset rim or less and do they fit without flares? I gather a serious camel cut would be needed.

255/85x16 tyres are just slightly smaller than the simex tyres above. They only just clear the guards on the standard offset. I think with 0 offset they would hit the guards and would need flares of some type. As for front and back clearance it only need a standard camel cut. I did have to remove the mud flap steel mount as it hits on the bent bit, You can take them off and flatten then out and refit though.

Does this mean that the front tyres scrub when turning or was there another cause for the deminishing turning circle?

The tyres hit on the radius arms when turning, it clears the body ok.

I run 235/85's with a 2" lift and camel cut, no rubbing at all, flexes well..

I have been running 33s for a few years now. Got the rims and tyres new, cant remember the offset.
Big guard cut needed as the correct offset brings the wheels out just enough to prevent rubbing on full turn.
I had to re drill the swivels also to get the steering geometry right. Fun and games.

Im reading a lot about lifted units. Would that even make a difference? I mean your bump stop will dictate your final position... Bigger springs will give you a better starting position but under flex the diff will still hit the stops.
Meaning bigger tyres will rub. Unless you cut the guards or do a body lift.
