35 In Tyres

Except no one has ever gone bigger than stock with them.

How big are the CWP's and how much pinion offset ?
How big are the CV's and shafts ?

35's are a big leap up from stock, that's a lot of extra load on the driveline.

I would think gearing, both on and off road would be an issue too ?

I know nothing of the independent suspension Landy drivelines but know that when we change one thing it has a lot of (potential) repercussions.
Nothing is ever simple.

No, I own the car, the car does not own me. While I love my rover I am not about to let fear of a potential repair cripple me into an overly conservative use of the car *gearbox. If premature wear is evident due to the tyre choice I will change the tyres one step down to the slightly narrower 285 75 R18 and if required, repeat to get the best performance with adequate life of the associated components.

Yeah, but stock old land rovers break stock axles. Stock L322's don't break them, so if I was a betting man, I'd say strong enough, but I have nothing to support that. Looks like Jonny will find out for us.:)

The drivetrain is pretty tough on the L322, as mentioned even with std tyres etc and conservative use the trans in the diesel is a weak point....

How did this go Jon?

Any further development with the rim choice?

Ive got cooper 33's on my 03 L322 on the STD 18" rims (PS VY Commodore rims fit 120 x 5 stud patern) and 17" steel rims will fit over the STD brakes but not the Brembo.

But with my AT3 275/65R18 Coopers they do scrub a bit but only just, and its mainly on severe bumps or if on the lowest height setting, No dramas off road height. And NO road noise from the tyres, love them.:D
