Inspecting Your Tires andWheel Valve Stems
Periodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that may be wedgedin the tread grooves. Check the tireand valve stems for holes, cracks,or cuts that may permit airleakage and repair or replace thetire and replace the valve stem.Inspect the tire sidewalls forcracking, cuts, bruises and othersigns of damage or excessivewear. If internal damage to the tireis suspected, have the tiredemounted and inspected in caseit needs to be repaired or replaced.For your safety, tires that aredamaged or show signs ofexcessive wear should not be usedbecause they are more likely toblow out or fail.
Improper or inadequate vehiclemaintenance can cause tires towear abnormally. Inspect all yourtires, including the spare,frequently, and replace them ifone or more of the followingconditions exist:
Tire Wear
When the tread is worn down toone sixteenth of an inch (2 mm),tires must be replaced to helpprevent your vehicle from skiddingand hydroplaning. Built-intreadwear indicators, or wear bars,which look like narrow strips ofsmooth rubber across the treadwill appear on the tire when thetread is worn down to onesixteenth of an inch (2 mm).
When the tire tread wears downto the same height as these wearbars, the tire is worn out and mustbe replaced.
Damage
Periodically inspect the tire treadsand sidewalls for damage (suchas bulges in the tread or sidewalls,cracks in the tread groove andseparation in the tread orsidewall). If damage is observed

If you feel a sudden vibration orride disturbance while driving, oryou suspect your tire or vehiclehas been damaged, immediatelyreduce your speed. Drive withcaution until you can safely pulloff the road. Stop and inspect thetires for damage. If a tire isunder-inflated or damaged,deflate it, remove wheel andreplace it with your spare tire andwheel. If you cannot detect acause, have the vehicle towed tothe nearest repair facility or tiredealer to have the vehicleinspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb orpothole can cause the front endof your vehicle to become
misaligned or cause damage toyour tires. If your vehicle seems topull to one side when you’redriving, the wheels may be out ofalignment. Have an authorizeddealer check the wheel alignmentperiodically.
Wheel misalignment in the frontor the rear can cause uneven andrapid treadwear of your tires andshould be corrected by anauthorized dealer. Front-wheeldrive vehicles and those with anindependent rear suspension (ifequipped) may require alignmentof all four wheels.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Tire Rotation
Note:If your tires show unevenwear ask an authorized dealer tocheck for and correct any wheelmisalignment, tire imbalance ormechanical problem involvedbefore tire rotation.
Note:Your vehicle may beequipped with a dissimilar sparewheel and tire assembly. Adissimilar spare wheel and tireassembly is defined as a sparewheel and tire assembly that isdifferent in brand, size orappearance from the road tires andwheels. If you have a dissimilarspare wheel and tire assembly it isintended for temporary use onlyand should not be used in a tirerotation.
Note:After having your tiresrotated, inflation pressure must bechecked and adjusted to thevehicle requirements.
Rotating your tires at therecommended interval (asindicated in the ScheduledMaintenance chapter) will helpyour tires wear more evenly,providing better tire performanceand longer tire life. Sometimesirregular tire wear can becorrected by rotating the tires.

•Purchase chains or cables from amanufacturer that clearly labels bodyto tire dimension restrictions. The snowchains or cables must be mounted inpairs on the front or the rear tires only.
•Do not exceed 30 mph (50 km/h) ifrecommended by the chainmanufacturer while using snow chains.
•Install cables securely, verifying thatthe cables do not touch any wiring,brake lines or fuel lines.
•Drive cautiously. If you hear the cablesrub or bang against the vehicle, stopand retighten them. If this does notwork, remove the cables to preventvehicle damage.
•Remove the tire chains when they areno longer needed. Do not use tirechains on dry roads.
If you have any questions regarding snowchains or cables, please contact yourauthorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
WARNING: The tire pressuremonitoring system is not a substitute formanually checking tire pressures. Youshould periodically check tire pressuresusing a pressure gauge. Failure tocorrectly maintain tire pressures couldincrease the risk of tire failure, loss ofcontrol, vehicle rollover and personalinjury.
WARNING: If the tire pressuremonitor sensor becomes damaged itmay not function.
Note:You should only use tire sealants inroadside emergencies as they could causedamage to the tire pressure monitoringsystem sensor.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflatedto the inflation pressure recommended bythe vehicle manufacturer on the vehicleplacard or tire inflation pressure label. (Ifyour vehicle has tires of a different sizethan the size indicated on the vehicleplacard or tire inflation pressure label, youshould determine the proper tire inflationpressure for those tires).
As an added safety feature, your vehiclehas been equipped with a Tire PressureMonitoring System (TPMS) thatilluminates a low tire pressure telltalewhen one or more of your tires issignificantly under-inflated. Accordingly,when the low tire pressure telltaleilluminates, you should stop and checkyour tires as soon as possible, and inflatethem to the proper pressure. Driving on asignificantly under-inflated tire causes thetire to overheat and can lead to tire failure.Under-inflation also reduces fuel efficiencyand tire tread life, and could affect thevehicle’s handling and stopping ability.
Please note that the TPMS is not asubstitute for proper tire maintenance, andit is the driver’s responsibility to maintaincorrect tire pressure, even if under-inflationhas not reached the level to triggerillumination of the TPMS low tire pressuretelltale.
Your vehicle has also been equipped witha TPMS malfunction indicator to indicatewhen the system is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequencewill continue upon subsequent vehiclestart-ups as long as the malfunction exists.
