I have a set of vette rally rims 15X8 from a 78 vette. Does anyone run a 255 50 15 all around. Even a 265 50 15 would be nice. Not sure of the back spacing of the stock vette rims. Just want run them on my 70 Chevelle. Thanks

You need to find out what the backspacing is on the rims....then you'll know what you can safely use. I have 15x8 with 4.5 inch bs and use 255/60/15 at all 4 corners with no problems, but they are SS-type rims.
