Since the new tires are about two inches taller than the stock ones, the stock spare is useless. I figured I'd dump it (-100lbs.= +1mpg.) When redoing the cover, I snapped one of the incredibly crappy knobs off at the spring clip I don't know if they sell them individually or not, but I guess I'll get four to ensure they are all the same colour black. Might need them if I ever take it off again...first time was certainly a success
