STARTING AND OPERATING 319 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. 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. 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), Inflation pressures specified on the placard are always which equals 1 psi (7 kPa) for every 12°F (7°C) for this "cold tire inflation pressure."

Tire Pressures for High Speed Operation Check tire pressures more often if subject to a wide range The manufacturer advocates driving at safe speeds of outdoor temperatures, as tire pressures vary with within posted speed limits. Where speed limits or conditions are such that the vehicle can be driven at high temperature changes. speeds, maintaining correct tire inflation pressure is very important.
