To the OPDoes it bother anyone else that the tires on the SS can't be rotated front to back?
No, fast cars are like that.
My STS-V was like that also. It is expected of this manner of automobile, I expect. Soft, fat tires are best for performance and the fattest ones belong in the rear. Soft tires give great performance, but, do not last long...so what. You bought the car for performance....right?
