Always look for bulges, cracks, cuts, penetrations and abnormal
tire wear, particularly on the edges of the tire tread, which may
be caused by misalignment or underinflation. If any such damage
is found, the tire must be inspected by a tire retailer at once. Use
of a damaged tire could result in tire destruction.
All tires will wear out faster when subjected to high speeds as well as hard
cornering, rapid starts, sudden stops, frequent driving on roads which are
in poor condition, and off road use. Roads with holes and rocks or other
objects can damage tires and cause misalignment of your vehicle. When
driving on such roads, drive carefully and slowly, and before driving again
at normal or highway speeds, examine your tires for any damage, such as
cuts, bulges, penetrations, unusual wear patterns, etc.
TIRE TREADWEAR INDICATORS "WEAR BARS"
Most tires contain wear indicators "Wear Bar" in the grooves of the tire
tread which show up when only 2/32nds of an inch (1.6 mm) of tread is
remaining. At this stage, your tires must be replaced. Tires worn beyond
this stage are extremely dangerous.
WARNING: Age
WARNING: Tires degrade over time depending on many factors
such as weather, storage conditions, and conditions of use (load,
speed, inflation pressure, etc.) the tires experience throughout their
lives. In general, tires should be replaced after six years regardless of
tread wear. However, heat caused by hot climates or frequent high
loading conditions can accelerate the aging process and may require
tires to be replaced more frequently.
You should replace your spare tire when you replace the road
tires or after six years due to aging even if it has not been used.
DO NOT OVERLOAD: DRIVING ON ANY OVERLOADED TIRE IS
DANGEROUS
The maximum load rating of your tires is molded on the tire sidewall. Do
not exceed this rating. Follow the loading instructions of the
manufacturer of your vehicle and this will ensure that your tires are not
overloaded. Tires which are loaded beyond their maximum allowable
loads for the particular application will build up excessive heat that may
result in sudden tire destruction. Do not exceed the gross axle weight
rating for any axle on your vehicle.
