How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they're underinflated. Check the tire's inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. Improved Ride with Light Load (2500 Series Vehicles Only) {CAUTION: Do not overload your vehicle or underinflate the tires. Overloading your vehicle or underinflating the tires can cause rapid loss of pressure and cause a serious crash. Only use reduced rear tire pressure when your vehicle meets the criteria for a light load. If you have a 2500 Series vehicle with LT245/75R16E size tires and you are operating your vehicle under light-load conditions, you can improve ride quality by adjusting both the front and rear cold tires to the recommended pressure shown on the Improved Ride label. 5-69
