Yup , guessed that ,lol
245/650 x 18" is what will take us through the next 10 years , it took me a few years to educate people up to the 235/610 x 17" tyres of the TOCA/S-2000 cars and the 18"'s are going to be even harder work as the profile is quite tall , most will struggle with this as Evo's ,Escort and Scoobys are marginal on Bodywork with the 64 profile tyres weve supplied .
Just to make the point about race tyres sizes ,the Pirellis specced for exactly the same rims on the Seats were 265/645 x 18" compared to Dunlops 245/650 x 18" !
