what size tires can i put on 93 cobra rims (17x7.5) so there will be no clearance issues? i have 255 45 17 all the way around now with a stock cobra suspension. i am going to put eibach springs on this winter and the 255 on the front look like there would be clearance issues. i now need new tires and would appreciate any input you all have. i was thinking of 235 45 on the front, 255 45 on the rear.
