Tire information
& Tire care – maintenance and
safety practices
Check on a daily basis that the
.
tires are free from serious da-
mage, nails, and stones. At the
same time, check the tires for
abnormal wear.
Inspect the tire tread regularly
.
and replace the tires before their
tread wear indicators become
visible. When a tire's tread wear
indicator becomes visible, the
tire is worn beyond the accepta-
ble limit and must be replaced
immediately. With a tire in this
condition, driving at even low
speeds in wet weather can cause
the vehicle to hydroplane. Possi-
ble resulting loss of vehicle con-
trol can lead to an accident.
To maximize the life of each tire
.
and ensure that the tires wear
uniformly, it is best to rotate the
tires every 6,000 miles (10,000
km). For information about the
tire rotation order, refer to "
rotation" �P501. Replace any
damaged or unevenly worn tires
at the time of rotation. After tire
rotation, adjust the tire pressures
and make sure the wheel nuts
are correctly tightened. For in-
formation about the tightening
torque and tightening sequence
for the wheel nuts, refer to "
tires" �P452.
& Determining compatibility of
tire and vehicle load capaci-
ties
The sum of four tires' maximum
load ratings must exceed the max-
imum loaded vehicle weight
("GVWR"). In addition, sum of the
maximum load ratings of two front
tires and of two rear tires must
exceed each axle's maximum
loaded capacity ("GAWR"). Original
equipment tires are designed to
fulfill those conditions.
The maximum loaded vehicle
weight is referred to Gross Vehicle
Weight Rating (GVWR). And each
Tire
axle's maximum loaded capacity is
referred to Gross Axle Weight Rat-
ing (GAWR). The GVWR and each
axle's GAWR are shown on the
vehicle certification label located at
the bottom of driver's side door
pillar.
The GVWR and front and rear
Flat
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the vehi-
cle's suspension, axles and other
parts of the body.
Therefore, this means that the
vehicle cannot necessarily be
loaded up to the tire's maximum
load rating on the tire sidewall.
& Adverse safety conse-
quences of overloading on
handling and stopping and on
tires
Overloading could affect vehicle
handling, stopping distance, and
vehicle and tire performance in the
following ways. This could lead to
an accident and possibly result in
severe personal injury.
