Tires 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 air pressures when the tires are cold. This means the vehicle has been parked for at least 3 hours, or driven less than 1 mile (1.6 km). Add or release air, if needed, to match the recommended cold tire pressures on this page. 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 get 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 driving conditions. DX and Canadian DX-G Tire Size P195/65R15 89H Cold Tire Pressure Front/Rear 32 psi (220 kPa , 2.2 kgf/cm ) LX, EX Tire Size P205/55R16 89H Cold Tire Pressure Front/Rear 32 psi (220 kPa , 2.2 kgf/cm ) Si Tire Size P215/45R17 87V Cold Tire Pressure Front/Rear 32 psi (220 kPa , 2.2 kgf/cm ) 244
