    Anyone know the widest tire you can put on a 15x7 rim? I got 225/70R15 right now but want to go to a 255/60R15 or wider if possible.

    I have 255/60/15's on a 7" wide rim on my GTO. Unless I go to a different rim on the rear, I'll be going to a 245/60/15.

    The 255's fit, but that's the narrowest rim that is recommended for them. I don't like the way they bulge out on a 7" rim. With an 8" rim they'd look much better to me.

    JMHO...

    That is exactly what I did last night!

    They fit quite nicely. :D
    (They're about 1/4" shorter than the 225/70, and a full inch wider.)

    265/50/15's on my n-90's... side walls are too short they look funny

    i think 255/60/15's would be better
    i have 255/60/15's on my firebird but on an 8" rim they are the perfect size for the rear (without goin crazy)

    255/60R15's are good for looks and straight line driving on a 7" rear wheel. They are terrible for corner handling. I have the 255's on the rear and the sidewalls flex or bounce from side to side a lot. I can give the car a shove on the side and watch the rear wiggle sideways for awhile. :eek:

    I have 275/60/15 DRs on my 15x7 steelies and they are fine in a straight line, but they suck cornering!

    Alright well I guess i'll go with the 255's. Some Radial T/A's or Firehawks should look pretty good on the back of my 81 Z.
