Tires 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 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). If you check the pressure when the tires are hot (the car has been driven several miles), you will see readings 4 to 6 psi (30 to 40 kPa, 0.3 to 0.4 kgf/cm ) higher than the cold reading. This is normal. Do not let air out to match the specified cold 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. Recommended Tire Pressures for Normal Driving Front: Tire Size 205/55R16 89W Cold Tire Pressure for Normal Driving 32 psi (220 kPa , 2.2 kgf/cm ) Rear: Tire Size 225/50R16 92W Cold Tire Pressure for Normal Driving 32 psi (220 kPa , 2.2 kgf/cm ) The compact spare tire pressure is: 60 psi (420 kPa , 4.2 kgf/cm ) These pressures are also given on the tire information label on the driver's doorjamb. The following chart shows the recommended cold tire pressures for most normal driving conditions and speeds. Tire pressures for high speed driving are the same as for normal driving. 190 Maintenance
