matt68gto Rock,
thanks for the replay. I put 255/60/15 on rear 8" and 215/65/15 on front 7".
I bought rally II's from wheel vintiques.

Rock On the back of my 68 I am running 295 R50 x 15s and 235 R 60 X15s on the front. I have a 474 CI and 200 HP of juice and even with two people in the back seat these do not rub or hit. The wheels are Rally IIs 8 1/2 in the rear and 7s in the front..

Rock

PaulPaladin My '66 has 245's on the back, on 14x7 or 8's....not exactly sure. Plenty of room

GasTiresandOil I have a 68 and am about to put on a set of 17x9" rims with 275s in the rear. They do not appear to rub, but you will also have to take into account the exhaust pipes the come down just under the rear inner fender well. Too big of pipe or bend will limit your size of the rear tire.

DaveH I'm running 245's on my '70 with plenty of clearance. The 15" wheels are so old I don't know what the backspacing is.
