Thread: 35 In Tyres

We are not talking about width but height. If you can get an engineer to sign off on a 5" increase in tyre size good luck to you. Even 33" tyres would be illegal under current laws.

Note: This clause does not apply to passenger vehicles that are four wheel drive or all wheel drive and certified as MA ADR category."

This means I do not have to flair the guards, provided they tuck under and not hit the guard when compressed.

I am not quite sure what you are getting at here.

Live axle legislation doesn't mean a thing for an L322.

The tyre / wheel can't protrude past the bodywork regardless of live axle / independent suspension.

I ran a tape measure over mine last night - I simply don't know how you intend getting them in there - there isn't enough room without carving out a huge amount out of the metal work and the inners. Even then, there isn't a huge amount of width to the air strut, so I still think you are going to end up with flares to cover the tyres that will be sticking out about 50mm.

Well we tested it out, present was my tyre guy and co, an engineer and myself.

The good:

They fit!!
Although they are 2.5 cm outside the wheel arch when the suspension articulates they find themselves clearing the wheel arch so I will cut the small metal flanges inside the wheel arch and hope it does not hit the guard on articulation at wheel lock.
The left hand rear fits perfectly
Engineer is happy it will pass a swerve test and is happy with the TD6 diff ratio to tyre size (not the V8 diff ratio) provided the tyres do not interfere with the body work (scrub anywhere).
The wheels appear to clear everything at normal suspension height (not road tested due to not being able to turn...)

The bad:

It will need new wheels that are somewhere between 10+ and 20+ offset (Pref 20).
It will need a bull bar as the front bumper and the associated front part of the plastic liner are in the way at even slight rates of turn, because of this we have no idea if it will hit the arches at lock on articulation (which will lead to a chopped guard).
The fuel filler hose and the protrusion on the rear right hand side wheel arch is very in the way and will need to move/ be removed.

The solution:

We are going to get the new wheels with an appropriate offset and fit 33 12.5 R18's and see if we can get the inside clearance right and do what needs to be done on the wheel arches in preparation for the 35's.
Hopefully the bull bar is released by then and the troublesome front plastic can be removed and we can retest the metal wheel arch clearance at articulation with steering lock.
Provided all is well replace the 33's with 35's when the 33's are past there useful life and keep the 32's handy for registration

I forgot to take any pictures with the wheel on but i grabbed a 15 inch version of the 35's and took a photo with it next to the car. They are alot bigger then the photo when they are pumped up on a rim.

Well done. I admire your perseverance. Still not sure if you can make it work, but it certainly will look like a weapon if you can. Watching with interest.

Keep the pics coming,

Jon are you concerned about extra stress on the drive train and steering from bigger tyres?

I'm wondering how well the CWP's, drive shafts and CV's will hold up to 35's.

Earlier Landy drivetrains don't, so I can't see why the IS versions will be any different, particularly with CV's on drive shafts.
