from those numbers says the front has a larger side wall then the rear?!

thats kinda weird
Do you know what those numbers mean? The first number, 245 means 245mm or 24.5cm...divide that by 2.54 and that will tell you how many inches wide it is. The second number, 40, is the precentage of the first number. So 40% of 24.5cm is the thickness/profile of the tire. Obviously the last number is the wheel size.

With that said, 40% of 245 is pretty close to 35% of 265 (1.6% differance)

Im going for a crazy handling car, so anything that will reduce the drivablilty is a big no no for me


if some one can give me a Strait up number for 8.5 frount and 9.5 rear, i will strait up get them
I would get on the Lexus boards and see what peoples experiences have been, i'm sure someone one there can tell you about clearance issues
