    I used the search function and read all the posts. Does anyone run 235/70/15 or 245/60/15 in place of the 225/70/15 that came factory on my 81 z? I have the five spoke factory wheels. Does a 255/70/15 on rear look ok? Pictures or comments please. I’m thinking b f Goodrich radial ta’s. Thanks

    The 245x60x15 seems to be the go to tire for these cars if you're staying on a 15" wheel. I ran 235x70x15 for several years and did get some minor rubbing issue in the front.

    I've used both 245/60/15 and 235/60/15 all around on my '78 Z28 on the factory wheels. The 245's rubbed ever so slightly on the front at full lock on the inner part of the fender liners.

    When I bought my 1979 Z-28 RS P235/60/15 all away around on Appliance 15 x 7 'Turbine" wheels. I later put P245/60/15 in back.and no issues .And if you have any issues with rubbing in the back.You can always bend in the lip.

    I want to run 235/70/15 all around, but not if it rubs on every bump. I like the slightly taller and wider tire. With an overdrive I don’t want a shorter tire. Maybe if I saw a pic of 245/60? Was the rubbing with 235/70 on turns or driving? It’s only 1/2 an inch wider and taller.
