      Maybe it's your particular car or wheel backspacing,Dennis. I've seen lots of 68-72 A-Bodies run 315's on the rear w/o clearance problems. KAA's 70 SS El Camino has 17x11 ZR-1 wheels with 315's mounted and that thing is a slotcar. 5.75" backspacing is not enough for a 17x11 rim as 6" is a zero offset. KAA is running either 6.25" or 6.375".

      On my former 68 El Camino,I tried some 18x10 OZ Monte Carlos & BFG 295/35/18 tires that came off my 85 Corvette and there was still lots of room left. If I had known then what I know now,that car would have had 315's on it back in 98.

      I will concede the point that what works on the street won't necessarily work on the track. KAA's car has been on the track,though.
