g. TIRE TREAD TYPES MILITARY TACTICAL TIRES.
(1) HMMWV Tires. The HMMWV tire is non-
directional, All-Terrain tread. It provides good traction in
either mud or snow, on dirt or temporary roads, and cross-
country. They are also practical for hard-surfaced roads. They
are available as bias or radial construction. Because radial
tires run cooler than bias constructed tires and the increased
sidewall and tread deflection of radial tires, HMMWV radials
will provide longer tread life and better sand and snow
mobility than HMMWV bias tires.
(2) HEMTT Tires. As with many military tires, the
HEMTT tire is available with various tire designs, tire brands
and from various manufactures. These tires provide good
traction in either mud or snow, on dirt or temporary roads, and
cross-country. They are also practical for hard-surfaced roads.
Even though some HEMTT tires brands appear to be
directional they are in fact non-directional and test have
proven them to work well in either direction.
(3) Military Non-Directional, Cross Country
(NDCC) Tires. Military non-directional, cross country tires
give good traction in mud or snow, on dirt or temporary roads,
and cross-country. They are also practical for hard-surfaced
roads. These tires have non-directional cross-country or mud-
and-snow tread design with bar-type lugs. Nondirectional
tread indicates that the tread pattern is equally effective in
either direction of rotation. On some NDCC tires the direction
of tread is the same no matter which way the tire is mounted.
However some of the newer model NDCC tires tread gives
the appearance of being directional as their treads point in
different directions when mounted differently. Even though
these newer NDCC tires appear directional they are not with
regards to performance as the tread pattern is equally effective
in either direction of rotation.
