Economy The wrong tire pressure can cause uneven wear patterns in the tire tread. These abnormal wear patterns will reduce thetread life, and the tire will have to be replaced sooner. Too little pressure also makes it harder forthe tire to roll, and this uses up more fuel. Ride comfort and vehicle stability The superior riding experience built intoyour vehicle partly depends on the correcttire pressure. Too much pressure gives an uncomfortable and jarring ride. Too little pressure feels as if your vehicle is slow torespond. Unequal tire pressures can make steering your vehicle uneven and unpredictable.
The tire pressure for your vehicle under nor- mal driving conditions is listed on the placard attached to the driver’s door sill. (Refer to “Tire and loading information plac-ard” on page 11-3.) The recommended infl
ation pressures under
normal driving conditions should be used forthe tires listed below.
Tire pressures should be checked, and adjusted if necessary, at least once a month. Pressures should be checked more often whenever weather temperatures changeseverely, because tire pressures change with outdoor temperatures. The pressures listed are always “cold inflation pressure”.Cold inflation pressure is measured after the vehicle has been parked for at least three hours or is driven less than 1 mile (1.6 km)after having been parked for three hours.Cold inflation pressure must not go above the maximum values molded into the tire side- wall. After driving several miles, your tireinflation pressure may increase 2 to 6 psi (14 to 41 kPa) from the cold inflation pressure. Do not let air out of the tires to get back to thespecified cold pressure, or your tires will be too low. Check your tires each time you refuel. If onetire looks lower than the others, check the pressure for all of them. You should also take the following safety pre-cautions:
Keep your tires inflated to the recom- mended pressures. (See the tire and load- ing information placard attached to the driver’s door sill.) Stay within the recommended load limits. Make sure that the weight of any load in your vehicle is evenly distributed. Drive at safe speeds. After filling your tires to the correct pres- sure, check them for damage and airleaks. Be sure to reinstall the caps on thevalve stems.

Replacing tires and wheels
CAUTION Avoid using different si
ze tires from the one
listed and the combined use of different types of tires, as this can affect drivingsafety. Refer to “Tires and wheels” on page 11-7. On all-wheel drive vehicles, always use tires of the same size, same type, and same brand, and which have no wear differences. Usingtires that differ in size, type, brand or the degree of wear, will increase the differential oil temperature, resulting in possible damage to the driving system. Further, the drive train will be subjected to excessive loading, possi-bly leading to oil leakage, component sei- zure, or other serious problems.
