Anyone running this tire combo? 255/60/15 front 275/60/15 rear. Any rubbing problems on front? SSI wheels.

 

I think a lot will depend upon the wheel width, wheel backspacing, and vehicle ride height.

On my 70 Supreme with 255-60-15s on front, the tire would rub the fender lip on turns. I have read that some folks had similar issues, and then other folks had no issues. I swapped to 245-60s and no rubbing issues.

The 275-60s on back should be fine with the correct wheel backspacing as the rear fender wells are huge.

 

Thanks I think I will stay away from the 255/60 and maybe go to the 245/60, maybe put the 255/60 on the rear, just checked my wheels are only 7 inches wide

 

you could also run 245's all around and put 1" spacers on your rear hubs to push the rear tires out a bit more. You'll benefit from still being to rotate all 4 tires around and won't have to worry about what to do for spare tire...
