They do. You can stuff a 325 tire back there and the only issue will be with the quad shocks. If the car is lowered you may have some rubbing on the inside fender well,.. but most of the time 315's on a 10 - 11 inch wheel with a 6.5 BS fit fine.

12inch with a 8.5 inch BS is not gonna work. It will rub like hell. Will need a 2 inch spacer to bring it away from the inner fender well. I dont like running wheel spacers on rear wheels. Asking for problems if you dont use thicker longer studs.
