ABS/Traction control and rolling diameter variance
Does anyone know the acceptable range of variance for the Corvettes ABS and traction control systems to stay happy? I am experimenting with some wheel/tire sizes but I don't know how far off I can go in terms of rolling diameter.
The factory staggered size tires have a 3.75% rolling diameter difference. I don't know how much further this can be pushed without affecting the performance of the ABS and traction control system.
Anyone have any insight on this topic?

As a general rule from what I've read in the past, try to have about a 1" larger diameter tire in the rear. The percentage values you're looking for should be somewhat close to your stated values and that will keep the ABS happy. It also looks correct. I'm pretty sure that you won't have much to worry about if you follow the 1" "rule". Due to the way the Vette is made, the most difference I could even imagine from front to rear would be if you ran a BIG 28" diameter rear tire (really tall, be close to rubbing) and a 25.5" front diameter tire. That would be 2.5" difference. It would look unusual and still not sure if it would set off the ABS.
