MAINTENANCE
n Wear Indicators
The groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower
than elsewhere on the tire. If the tread
has worn so low that the indicator is
exposed, replace the tire. Worn out
tires have poor traction on wet roads.
Using tires that are excessively worn or improperly inflated can cause a
crash in which you can be seriously hurt or killed. Follow all instructions
in the owner's manual regarding tire inflation and maintenance.
n Tire and Loading Information Label
The label attached to the driver's doorjamb provides necessary tire and
loading information.
La bel
Exa mple
1. The number of people your vehicle can carry.
2. The total weight your vehicle can carry. Do not exceed this weight.
3. The original tire sizes for front, rear, and spare.
4. The proper cold tire pressure for front, rear, and spare.
Tire and Wheel Replacement
n
Replace your tires with radials of the same size, load range, speed rating,
and maximum cold tires pressure rating (as shown on the tires' sidewall).
Using tires of a different size or construction can cause certain vehicle
systems to work incorrectly. It is best to replace all four tires at the same
time. If that isn't possible, replace the front or rear tires in pairs.

Example of a wear
indicator mark
If you change or replace a wheel, make sure that the wheel's specifications
match those of the original wheels. Only use TPMS-specified wheels
approved for your vehicle.
Installing improper tires on your vehicle can affect handling and stability.
This can cause a crash in which you can be seriously hurt or killed.
Always use the size and type of tires recommended in the Owner's
Manual.
Tire Service Life
n
The life of your tires is dependent on many factors, including driving
habits, road conditions, vehicle loading, inflation pressure, maintenance
history, speed, and environmental conditions (even when the tires are not
in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires
reach five years old. All tires, including the spare, should be removed from
service after 10 years from the date of manufacture, regardless of their
condition or state of wear.
n Winter Tires
If driving on snowy or frozen roads, mount all season tires marked "M+S",
snow tires, or tire chains; reduce speed and maintain sufficient distance
between vehicles when driving. For winter tires, select the size and load
ranges that are the same as the original tires, and mount them to all four
wheels.
Tire Chains
n
Install tire chains on the front tires only. Because your vehicle has limited
tire clearance, we strongly recommend using the following chains:
Cable type: SCC Super Z LT - ZT735
Mount chains as tightly as you can and make sure that they do not touch
the brake lines or suspension.
