Main Menu Table Of Contents Tires 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. 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/cm ) per month. Remember to check the spare tire at the same time. Check the pressure in the tires when they are cold. This means the vehicle has been parked for at least three hours, or driven less than 1 mile (1.6 km). Add or release air, if needed, to match the recommended cold tire pressure. If you check air pressures when the tires are hot [driven for several miles (kilometers)], you will see readings 4 to 6 psi (30 to 40 kPa, 0.3 to 0.4 kgf/cm ) higher than the cold readings. This is normal. Do not let air out to match the recommended cold air pressure. The tire will be underinflated. You should use your own tire pressure gauge and use it whenever you check your tire pressures. This will make it easier for you to tell if a pressure loss is due to a tire problem and not due to a variation between gauges. While tubeless tires have some ability to self-seal if they are punctured, you should look closely for punctures if a tire starts losing pressure. Recommended Tire Pressures The following charts show the recommended cold tire pressures for most normal and high-speed driving conditions. Tire Size P215/50R17 93V Cold Tire Pressure for Normal Driving Front: 32 psi (220 kPa , 2.2 kgf/cm ) Rear: 30 psi (210 kPa , 2.1 kgf/cm ) Maintenance The compact spare tire pressure is: 60 psi (420 kPa , 4.2 kgf/cm ) For convenience, the recommended tire sizes and cold tire pressures are on a label on the driver's doorjamb.
