Wheel with asymmetrical hump
(AH)
If the rim has a so-called asymmetrical
hump in place of the usual symmetrical
hump, the tire will remain on the rim
much longer if air pressure is lost, thus
enabling the car to be braked to a
standstill more easily. A further advan-
tage of the asymmetrical hump wheel
rim is that special tires are not needed.
