When you inflate the tires to the recommended inflationpressures, the factory-installed wheels and tires are designed inorder to handle loads to the tire's rated load capacity. Incorrecttire pressures, or under-inflated tires, can cause the followingconditions:
Vehicle handling concernsPoor fuel economyShortened tire lifeTire overloadingInspect the tire pressure when the following conditionsapply:
The vehicle has been sitting at least3-hours.The vehicle has not been driven for more than1.6-km (1-mi).The tires are cool.Inspect the tires monthly or before any extended trip. Adjustthe tire pressure to the specifications on the tire label. Installthe valve caps or the extensions on the valves. The caps or theextensions keep out dust and water.
The kilopascal (kPa) is the metric term for pressure. Thetire pressure may be printed in both kilopascal (kPa) and psi. Onepsi equals 6.9-kPa.

Tires with a higher than recommended pressure can cause thefollowing conditions:
A hard rideTire bruisingRapid tread wear at the center of the tireTires with a lower than recommended pressure can cause thefollowing conditions:
A tire squeal on turnsHard steeringRapid wear and uneven wear on the edge of the treadTire rim bruises and tire rim ruptureTire cord breakageHigh tire temperaturesReduced vehicle handlingHigh fuel consumptionSoft ridingUnequal pressure on the same axle can cause the followingconditions:
Uneven brakingSteering leadReduced vehicle handlingRefer to the Tire Placard for specific tire and wheelapplications and tire pressures.
Removing the Flat Tire and Installing the Spare Tire
Do a safety check before
proceeding. See If a Tire Goes
Flat for more information.
For vehicles with a wheel cover
or center cap, pull the cover or
center cap away from the
wheel to remove it. Store the wheel cover in the cargo area
until you have the flat tire
repaired or r ...
