Get the 225/70/15's. If the 235s rub now, the 255s will rub worse.

255/60/15 should not rub in back. Many run smaller 235 or 245/60/15 in front.

The 225/70's should definitely offer no clearance problems and would therefore be safe. However the 255/60's were offered as optional on the '79 Corvette. With stock wheels (stock off-set's) the 255/60 should fit as well with no problems.

A 235/70-15 is a taller tire than a 225/70 by about 3/4" and could be the reason they were rubbing. The 255/60-15 is actually slightly shorter than even the 225/70.

I run 255/60-15's all the way around on my stock '73 with only minor rubbing on the left front frame rail (actually on the head of the carriage bolt that holds the steering box on the frame) at full lock. It keeps the head of the bolt smooth and shiny.

Are you using stock wheels?

Good luck... GUSTO

Are the 235/70/15 tires rubbing ft. or rear? Are any of the 235/70/15 tires still good?
If yes, you might buy 2 tires now of a different size.

The option tire size in 1979 was 255/60/15. Shouldn't be a probelm.

Yes, the front was expected so you could get 225/70/15 for the front so the diameters are close. Then later get 255/60/15 for back. Check carefully for if/where they are rubbing in back. The spring can easily be adj. to raise rear.

The back tires wear fast on mine.
