Tires To safely operate your vehicle, your tires must be the proper type and size, in good condition with adequate tread, and correctly inflated. The following pages give more detailed information on how to take care of your tires and what to do when they need to be replaced. Inflation Guidelines Keeping the tires properly inflated provides the best combination of handling, tread life, and riding comfort. ● Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Overinflated tires can make your vehicle ride more harshly, are more prone to damage from road hazards, and wear unevenly. Use a gauge to measure the air pressure in each tire at least once a month. Even tires that are in good condition may lose 1 to 2 psi (10 to 20 kPa, 0.1 to 0.2 kgf/cm2) per month. Remember to check the spare tire at the same time. ● 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 this owner's manual regarding tire inflation and maintenance. The tire pressure monitoring system (TPMS) warns you when a tire pressure is low. See page 455 for more information. Even though your vehicle is equipped with TPMS, we recommend that you visually check your tires every day. If you think a tire might be low, check it immediately with a tire gauge. 540
