If your vehicle has P255/55R18 size tires installed on the rear axle, they will require inflation pressure adjustment when driving your vehicle at speeds above 99 mph (160 km/h). Set the cold inflation pressure, for the rear tires only, to the maximum inflation pressure shown on the tire sidewall, or 36 psi (248 kPa), whichever is lower. See the example following. When you end this high-speed driving, return the tires to the cold tire inflation pressure shown on the Tire and Loading Information label. See Loading Your Vehicle on page 4-22. Example: You will find the maximum load and inflation pressure molded on the tire's sidewall, in small letters, near the rim flange. It will read something like this: Maximum load 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press. For this example, you would set the inflation pressure for high-speed driving at 36 psi (248 kPa). The inflation pressure for the front tires should be set to the cold tire inflation pressure shown on the Tire and Loading Information label.
