Tires 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 (0.3 to 0.4 kgf/cm 2 , 30 to 40 kPa) 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 The following chart shows the recommended cold tire pressures for most normal driving conditions and speeds. Tire pressures for high speed driving are shown on page 223. These pressures are also given on the tire information label on the driver's doorjamb. Tubeless tires have some ability to self-seal if they are punctured. However, because leakage is often very slow, you should look closely for punctures if a tire starts losing pressure. The compact spare tire pressure is: 60 psi (420 kPa , 4.2 kgf/cm 2 ) Maintenance
