Gtr Tyre & Wheels Size Problem

[PAV34]

So i have BBS LM's on my 32 GTR right....

But the rears are 9" wide with 255/40/17 tyres

And the fronts have 8" wide with 235/45/17 tyres

As you know this isnt good for the 4wd system

What if i put 245/45/17 all round, would that be ok? I really like these wheels and dont want to sell them, but if this doesnt work i will.

No problem from an ATTESA perspective.

So there wont be any other issues then?

[eddieeeee-ro]

should be fine, the ATTESA system plays up if the rolling diameters arent the same.

255/40's and 235/45's will be better for the ATTESA system than 245/45 and 235/45.

But smaller tyres on the front just makes them understeer even worse. A 10% narrower tyre on the end of the car that weighs 50% more can't possibly be a good idea.

yeh that was only regarding rolling diametre and its relationship to the attesa, handling is another story.

Yeah thats what i have, i think its about a 2% difference in rolling diameter, yet the Front Torque Gauge still goes up to about 10 when doing around 100kms on the freeway - will that still cause problems?
