Tires: 6 INSPECTION AND MAINTENANCE Tire Inflation Pressure Tire inflation pressure should be checked when the tire is cold. "Cold tire inflation pressure" is the pressure in a tire that has been driven less than 1 mile (1.6 km) or has been standing for three hours or more. • Recommended Cold Tire Inflation Pressure of Original Tires Recommended Cold Tire Inflation Pressures Front Tires Rear Tires Spare 230 kPa 33 psi 230 kPa 33 psi 230 kPa 33 psi temperature. If you adjust the tire pressure in a garage that is warmer than the outside temperature, you should add 1 psi to the recommended cold tire inflation pressure for every 10°F difference between garage temperature and outside temperature. Measuring air pressure Use the following steps to achieve proper tire inflation: 1) Identify the recommended tire pressure on the vehicle's Tire and Loading Information Label or in the owner's manual. 2) Remove the valve cap from the tire valve stem. 3) Using a reliable pressure gauge, measure the tire inflation pressure by pressing the tire gauge firmly onto the valve to get a pressure measurement. Remember that inflation pressures should be checked when the tires are "cold", meaning before they have been driven one mile or after sitting for three hours or more allowing the tire to cool to ambient air temperature. 4) If the air pressure is too high, slowly release the air by pressing on the tire valve stem with the edge of the 54G307 The front, rear and spare tire pressure specifications for your vehicle are shown below and are listed on the Tire and Loading Information Label, which is located on the driver's door lock pillar. The Tire and Loading Information Label contains the following information: • Seating Capacity • Maximum Allowed Combined Weight of Occupants and Cargo • Original Tire Size NOTE: The tire inflation pressure will change due to changes in atmospheric pressure, temperature or tire temperature when driving. To reduce the chance that the low tire pressure warning light will come on due to normal changes in temperature and atmospheric pressure, it is important to check and adjust the tire pressures when the tires are cold. Tires that appear to be at the specified pressure when checked after driving, when the tires are warm, could have pressure below the specification when the tires cool down. Also, tires that are inflated to the specified pressure in a warm garage may have pressure below the specification when the vehicle is driven outside in very cold 7-27 79K21-03E
