Tyre Sizes

[art burgess]

do the wheels and tyres on a stagea have to be the same diameter,

some fwd cars need the tyres to be within a couple of mill of each other,

will the tranfser boxes be affected...?

Affirmative ghostrider, all wheels must be the same diameter to avoid stuffing up your ATTESA system.

Yeah Art they do, otherwise the Nissan spawned brain thinks that the wheels are slipping.... and starts driving the car in 4WD to compensate.

There are some really good tyre calculators online now.... if you're thinking of changing they can be useful.

Otherwise do a search, this subject is well covered.

They don't have to be the same tyres. As long as the rolling dimension is the same or within something like a 2% tolerance (don't quote me on the exact percentage) it's fine. This is to allow for wear and tear. i have different profile tyres front and back but the rolling dim is nearly the same (R - 235/45/17, F - 215/50/17)
