I am in need of some decent tires for my stock 72 but am having trouble finding any or any tire salesmen that know anything. I like the look of a wider tire and would like to go with BFG radial TA 255/15/60. I have seen others post that this size fits but with the price of tires, I just want to make sure. Any others with this size tire and do they work well? Stock size is 225/15/70
Chevrolet didn't authorize 60 series tires until the '78 model year after some modifications were done to the body panels for clearance. For model years prior to that, it seems to be a car by car thing whether 60 series fit OK or rub. Tolerances in body panel manufacture and whether springs have compressed all seem to make a difference.
The only way you'll know is to mount new tires and see. Stick with P225/70R15 and you know there will be no issues.
I have P215/70R15's, which is the radial metric equivalent to the original F70-15 for my '69 and they fill the tire wells quite nicely.
Apparently, 255's will fit on the back just fine. But, you will only be able to guarantee that 235's will fit in the front without rubbing. I have 235's on my '71 and they fill the wheelwells just fine. Tires wider than that may stick outside the fenders and increase the amount of 'road rash' on your paint.
I have BFG RWL TA 255 x 60 x r15 on all four on 8.5" rims and they are right at 26" diameter. The original tires are slightly greater in diameter. No rubbing including running them on VIR's track three weeks ago. Mine is a 1976. There is some kind of spacer on my rotors I guess it is where the wheel and tire mounts for clearance on the brake calipers I guess but I don't know how to measure to express that accurately to you. Mine work perfectly and I run them at about 30 psi in air, cold. On a track you'd run them up 3-5#'s more than that to stiffen the sidewall for the greater sidewall forces. You can see them on my photo gallery.
I labored over this decision for quite some time...
TODAY...I went out and replaced my 225/70/15 set which came with the car and is just about the only thing on it that I havent had to or elected to replace yet...and bought a set of BFG TA Radials in 255/60/15
Now, Ive only driven it home....but I had the installer drive it around in the parking lot slowly after he finished slapping them on. Ive got a SLIGHT fender rub at the back of the front left fender and a SLIGHT rub at the inner fender at the frame.....but not anything severe. I'll probably trim the fender slightly....but thats it..
You cannot beat the look. I contemplated 275's on back....but am glad I didnt do that. Too fat.. This set looks "right"..
