Mike, I have 295/50/15s on my CAV, with the standard fenders, and it barely fits. I doubt a 325 will fit unless you have some add'l fender extensions. In other words on full (or near full) compression you'll probably have tires rubbing on the wheel well. You might also find that the rear clam shell is not perfectly centered over the rear wheels, making the clearance problem more acute on one side v. the other side.
