Those tires are 28.9" in diameter and would be the main limitation. Probably OK in rear.

Those would be a really tall tire - nearly 3 inches taller than what you'd typically find on your car. They definitely will not fit in the front, but as padgett says above, they will likely fit in the rear if you like the ass-high look.

I have 255/70R15s on the rear of my Judge, are about 1/4" taller than the 235/75s. 235x60R15s on front are marginal for clearance.

Thanks guys, so the 70's are a 1/4" taller than the 75's?
Thought it might have been the other way around.

No 235/60R15 on front are 26" diameter. 235/75R15 you have are 28.9". My rear tires are 255x70R15 and 29.1" tall. Thought I was clear. Guess not.

Use this.

A 235/75/15 (28..9")would be taller than a 235/70/15 (27..95").

But a 255/70/15 is taller because of the wider section width with the same 70 series profile.

The first number (235) is the section width in mm. The second number (70) means the sidewall height is 70% of its 235mm section width.

There’s limited room in the rear for a tall tire.

Honestly I would move them on to someone with a big Pontiac that they’re best suited for, they’re really not something you want to use and rear fitment is questionable.

If your Rally I's are stock, those are 14" and won't work with 15" tires.
