Thank youi but I realize the tires are staggered. What I am trying to find out is if the wheels the tires are on are staggered. You can fit those tires on the same size rim, and the Cadillac specs do not specify.
I don't get many all wheel drive STSs in, if I see one I'll check the wheels.
If it's like the SRX the wheels are the same size but the tires are different front to rear.
Even though the profile of the tire is different most of the overall dimensions are the same. (like the radius and circumference)
