im thinking of changing the tyres on my r35 for a non run flat does any one know if this is ok r will it mess with the traction control ?? also i dont think the exact size is available in a non run flat so was wondering if any one else is running a slighty different tyre size on std wheels ??:chairshot

As long as you run the same tyre diameter front and rear,it will not mess up the tracion control or anything else....the Race academy cars had pirelli´s on,worked fine,but id say you should use a tyre with a hard sidewall,as RFT´s are very stiff and so the car is made/setup for these tyres from the suspension side,using a soft tyres could kill some performance

Example: if you go for 255/35/20 and 285/30/20 this gives the same diameter front and rear,but your overall a bit smaller in diameter then the stock 255/40/20 and 285/35/20....maybe costs 10km/h topspeed,but nothing else

This is very true you should have no problem.

Blackcircles has Pirellis shown in the correct size (along with Dunlop and Bstone run flats).

I had a puncture at the weekend and so I had to look!

Anyone know the published dealer prices.
