Not sure if this helps much..But I know you can fit a 295/50/15 on an 8" rim. Not sure if they will fit a thirdgen wheel well though. I had them on and old set of corvette rally 15x8s on a 70 rs camaro.

i have 255 -70 -15 with a four and a half inch rear spacing.you could probably get away with 295 if you had 5 or 5 and a half inch back spacing
