Re: Anyone ran 295/65r15 Rear Tires in a 66?
Not a great answer to your question, but I tried those on my 68 El Camino. I got the backspacing right to get them to fit, but had two issues. The sidewalls, being very tall, would flex quite a bit and would rub slightly on cornering. I played with various wheel spacers and whacked the heck out of my inner fenders for clearance. I got them so that the rubbing was infrequent, but never did get it completely eliminated. Also, they sit very tall causing the rear of the car to sit quite high in the air with the stock springs. Lowering for the proper look wasnt an option due to the clearance/rubbing issue. I finally switched to 275/60-R15s.
Certainly the 68 and 66 wheel wells are different, but I imagine that, if anything, the 68 would have more clearance.
