I have just finished painting a set of SSIII color key Olds wheels for my 72 Cutlass convertible. I have researched the various tire sizes here and it seems there is a lot of room in the Cutlass wheel wells for many different tire sizes. I woulds like to fit a set of 215/75/15 tires that are about 28 inches tall. The SSIII's have a backset of approx 3.5" on these 15" x 7" wheels. Will this tire size rub the wheel lips? Right now I have 14" chrome SSIII"s that just look too small for the car.

You should be fine. I 225/70/15 on the front a '72 with stock springs and shocks. You didn't mention if your suspension has been altered; if not lowered your choice should be a good one.

I agree that they should fit fine. I currently have 245-60-15s on the front of mine with no issues.

Sean Blake

Thank you gentleman. It is always best to check with you folks who have already changed to 15" wheels and tires.

I forgot to mention that back in the late 70s/early 80s my 70 Supreme had 225-70-15s on a set of factory '77 Monte Carlo wheels with no issues.

Going for the 4x4 look?

Those tires are quite tall. I've run 255/60-15s all around on a 69 H/O with no real problems, but even those are about a half in smaller in diameter (and almost two inches wider). Personally I'd go with something like a 235/60-15.
