Mk2 GT3 tyre sizes on a MK1!!??

[Dave 321]

Has anyone tried the MK2 size tyres on MK1 wheels?? I want Michelin Pilot Sport 2's, but i think they are only available in 235/40/18 and 295/30/18..??Are these MK2 tyre sizes?? Are the mk2 wheels wider??? Cheers

Mk1 wheels: 8 (f) 10 (r)
Mk2 wheels: 8.5 (f) 11 (r)

And the 235/40 and 295/30 tyres will fit the Mk1 wheels.

I run 235/40 System Corsas on the 8" fronts with no problems.

I have not heard of anyone running 295/30/18's on the rear of a MK1 they would fit on the rims OK but I would guess the rear arches would need rolling like the MK2 & RS for them not to rub.

Cheers lads, Adrien how do you find the System Corsas???

Excellent tyre. Whereas the Rossos pushed on through many corners and just go off after 4-5 laps (Bedford/Oulton), the Corsa Direczionales effectively dialed out the understeer completely. Worth noting, but on both sets of tyres, the geo was setup to the same trackday (road tyre) settings by JZ immediately prior to going out on track. I haven't had the chance to use the Corsa Direczionales in the wet yet, but I went with these instead of the Corsa Rs because I do use the car on the road in sometimes unpredicatable conditions.

The only problem is finding a matching tyre in 285 for the rear... I am thinking that the 295 Corsa Assimetricos may make the car feel over-tyred though... not sure, but I am tempted to give them a try.

Interesting - I wasn't aware that the Mk2/RS arches were rolled in comparison to the Mk1... are the panels even the same?
