Yes, upon further checking, the 255-70r15's rubbed on both left and right fenderwells. Even though the passenger side was approx. 1/2" toward the rear of the car, both sides were a problem. To refresh, those tires were 29.1" in diameter.

We gave up and took the tires back to the dealer and had him put 255-60r15's on the 7" Rally II's. These are 27" in diameter with a little more than 9" tread on the ground. These tires clear everything by more than 1"---fenderwells, springs, exhaust, and inner fenders.

As I said earlier, the car has 4.11 gears, so we will be at 3,500 rpm at 68.4 mph. Not as nice as the 29.1" tires, but tolerable.

Without doing a front alignment, the car steers straight, even after replacing the stock "A" arms with tubular ones. We'll see what the alignment shop says next week. We're lucky to have one here that actually knows how to align our old Pontiacs.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
