10-52 Vehicle Care If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Re‐ check the tire pressure with the tire gauge. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. WARNING (Continued) inflation pressure adjustment for high speed operation. When speed limits and road conditions are such that a vehicle can be driven at high speeds, make sure the tires are rated for high speed operation, in excellent condition, and set to the correct cold tire inflation pressure for the vehicle load. Set the cold tire inflation pressure to 35 psi (241 kPa) for the front and rear tires, when operating your vehicle at high-speed conditions. When you end high-speed driving return the tires to the cold inflation pressure shown on the Tire and Loading Information label. See Vehicle Load Limits on page 9‑12 and Tire Pressure on page 10‑51. How to Check Use a good quality pocket-type gauge to check tire pressure. You cannot tell if the tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are underinflated. Check the tire's inflation pressure when the tires are cold. Cold means the vehicle has been sitting for at least three hours or driven no more than 1.6 km (1 mi). Remove the valve cap from the tire valve stem. Press the tire gauge 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. Tire Pressure for High-Speed Operation { WARNING Driving at high speeds, 160 km/h (100 mph) or higher, puts an additional strain on tires. Sustained high-speed driving causes excessive heat build up and can cause sudden tire failure. You could have a crash and you or others could be killed. Some high-speed rated tires require (Continued)
