10-54 Vehicle Care 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. If your vehicle has P265/65R18 or P285/45R22 size tires and you will be driving at high speeds, speeds of 160 km/h (100 mph) or higher, set the cold inflation pressure to 20 kPa (3 psi) above the recommended tire pressure shown on the Tire and Loading Information Label. When you end this 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 9‑24 and Tire Pressure on page 10‑52. 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 gauge. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. Tire Pressure Monitor System The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. The TPMS sensors monitor the air pressure in your tires and transmit tire pressure readings to a receiver located in the vehicle. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.) 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)
