Tires Check tire pressures more often if subject to a wide range may look properly inflated even when they are under- of outdoor temperatures, as tire pressures vary with inflated. temperature changes. • Inspect tires for signs of tire wear or visible damage. Tire pressures change by approximately 1 psi (7 kPa) per 12°F (7°C) of air temperature change. Keep this in mind when checking tire pressure inside a garage, especially in the winter. CAUTION! After inspecting or adjusting the tire pressure, always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the valve stem. Example: If garage temperature = 68°F (20°C) and the outside temperature = 32°F (0°C) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this Inflation pressures specified on the placard are always outside temperature condition. "cold tire inflation pressure". Cold tire inflation pressure Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) is defined as the tire pressure after the vehicle has not during operation. DO NOT reduce this normal pressure been driven for at least three hours, or driven less than 1 build up or your tire pressure will be too low. mile (1.6 km) after a three hour period. The cold tire inflation pressure must not exceed the maximum inflation pressure molded into the tire sidewall.
