Bigger tires on SSII's?

Bigger tires on SSII's?
I put together two cars into one, a '72 with these R15 rims with 235/60R15 tires on them and another with SSIIs all around. Sadly, the tireshop says those unidentified R15 rims are completely warped, causing vibrations from 30 MPH and up.
I have a pair of SSII rims, the standard R14 ones like the ones on the front, with 205/75R14 on them. How wide a tire will those rims comfortably support? That would mean I'd have the nice SSII rims on both axles, which is only a plus.

The rough rule of thumb is that the tire section width should be +/- one inch of the wheel width. Personally I've run 245/60-14s and 255/60-15s on 7" wide SSII/III wheels with no problems. The real problem is that 245/60-14s just look too small in diameter for an A-body in my opinion, especially on the rear. Too much daylight left in the wheelwell.

I am not sure what sizes are available where you are at. I saw these 225 70 14 available at www.tirerack.com in either BF Goodrich or Firestone. They would give yo a taller tire option

It looks like a 235/70R14 is as tall as a the 205/75R14s I have in front, assuming the page I found is correct. The current rear tires, 235/60R15 are the same height. I guess that'd work.
SSII wheels only come in R15 for fullsize cars, yes? Do those have the same bolt pattern as the R14s?

Again, SSII/III wheels were ONLY made in the 5 x 4.75" bolt circle. The 15" versions were first used on the 1969 H/O and were available on the Cutlass line starting in 1973. They were not used on the full size cars until the downsized 1977 models came out, as that was the first time (since the J88) that the 4.75" bolt circle was used on the (then not so) big cars.
Didn't we just have this discussion in another thread last week?

I wouldn't know, this didn't become an interest area for me until today, when my rims were identified as the problem.
The confusion on my part is due to bad memory, I seem to have picked something along those lines up without getting it right.

you could do what i did i run 14's in the front and 15's in the rear to give it the big n little attitude. Front are 205 75 14 if i remembered right and the rears are 275 60 15

Most tires sold in the US are "all season" (M&S) and are a compromise. Like most compromises, OK most of the time but not the best at anything. Will never hold dry roads like a summer tire and never get the traction of a winter tire in messy weather.
