Tire sizing

[shifty]

Been looking at getting some new tyres as my Toyo T1R,s are starting to wear on the back and as the T1R is discontinued ive been checking out the newer R1R track and road tyre which seems to get decent press the only problem is size im running some work CR Kai,s 9.5x18 wrapped in 255x40x18 but the only sizes close to that are 245x40 255x35 or 265x35 there site say the 245 or the 265 are rated for 9.5 rims but what would be best I run quite a low ride (not as low as some) but low enough to need negative camber on the back so whats best or am I better of sticking with the size I have and find another tyre.

Anyone ? :wiggle

I run with 245 on a 10" rim on the front of mine if that helps

255 or 265 will be fine on a 9.5 rim, you should be running a 35 profile to keep the rolling radius as near to stock as standard anyway, not 40!

The issues I have is how low and wide I am to the archs I was told by someone that the 245-40 would be best but ive been told in the past a lower 35 on the 255 would allow more clearance .

I am also running 245 on a 10" rim.

255 or 265 will be excellent on a 9.5 rim, you should be operating a 35 information to keep the moving distance as near to inventory as conventional anyway, not 40!
