Tires To safely operate your car, 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 and when to check air pressure, how to inspect your tires for damage and wear, and what to do when your tires need to be replaced. Inflation 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 car ride more harshly, are more prone to damage from road hazards, and wear unevenly. 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. Use a gauge to measure the air pressure at least once a month. Even tires that are in good condition may lose one to two psi (10 to 20 kPa, 0.1 2 to 0.2 kgf/cm ) per month. Remember to check the spare tire at the same time you check all the other tires. Check the pressure in the tires when they are cold. This means the car has been parked for at least three hours. If you have to drive the car before checking the tire pressure, the tires can still be considered "cold" if you drive less than 1 mile (1.6 km). 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. CONTINUED Maintenance
