Default Same size wheels, all four?

My 03 has 17s and 18s respectively. I would like to know if I could just install 18" wheels on all four sides. That way I would be able to rotate my tires. There must be a reason why GM put the two different sizes on the car, and would like your input.

You cannot have all 4 tires the same size on the vette. You can use 18" rims all around but there needs to be about 1" difference in overall diameter between the front and rear. The traction control/active handling system programming requires that difference.

Thanks Chris, I thought there was a reason.

I run the same size 17's on my 02 Z06. Can't see that anything works any different. Most T1 racers do the same.

Some guys are running 18's all the way around for DE events.

I have the same size on all 4. I drive the car on the street with TC/AH/ABS on, no problem.
