I just bought a set of afs 03 cobra replicas and the rears are 18x10.5. My question is what would be the better tire the 295/35/18 or 315/30/18 Bfg drag radial? I would like to run the 315 but I do not want to run spacers and I think the 295 will be a little small. Sorry if this question has been asked I searched but could only find stuff on the 17" wheels.
