Wheel with asymmetrical hump
(AH)
The rim design with a so-called asym-
metrical hump results in a clearly
extended holding of the tire on the rim
in the case of a leak compared to the
usual symmetrical hump, so that the
vehicle can be braked to a stop more
safely. Another advantage of the asym-
metrical hump is that no special tire is
required.
