STARTING AND OPERATING 289 Inflation pressures specified on the placard are always "cold tire inflation pressure." Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least three hours or driven less than 1 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. inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this outside temperature condition. Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. Do not reduce this normal pressure build up or your tire pressure will be too low. 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 conditemperature changes. tions are such that the vehicle can be driven at high Tire pressures change by approximately 1 psi (7 kPa) per speeds, maintaining correct tire inflation pressure is very 12°F (7°C) of air temperature change. Keep this in mind important. Increased tire pressure and reduced vehicle when checking tire pressure inside a garage, especially in loading may be required for high-speed vehicle operation.
