Re: 15X7 rally wheel on 69 camaro coupe tire size
I have 15x7 Rally's all the way around. The Corvette Rally's were actually 15x8. As far as the tire size: I have P235/60/R15 all the way around on my 1969 Camaro. On the rear if the leaf springs are good you can get away with P255/60R15. I have seen some guys run P275/60R15 and in extreme cases back in the day a friend of mine was running N50-15 on the rear of his 1968 Firebird. This is equivalent to P315/50/15. That's really pushing it.
Bottom Line: I like having the same size all the way around on this car. But if you like a different look P235/60/R15 will work up front. The P215/65/R15 & P 225/60R15 as TSTONE said is common. The reason is that P215/65/R15 was original equipment on Z28's from 1982-1987. The 5.0L (305 equipped) IROC-Z also used this size from 1985-1990 and so did some RS Camaro's from 1989-1991. The P215's also were on Buick Grand National's, Pontiac Grand Prix's, Olds Cutlass and some other cars as well. The P225/60/R15 was original equipment on 5.0L V8 Ford Mustangs from roughly 1985-1991. These 2 sizes (P215/65/R15 & P 225/60/R15) will be made for years to come. As far as the rear the P255/60/R15 fits with no issues and in some cases the P275/60R15 will as well.
