9-51If you overfill the tire, release airby pushing on the metal stem inthe center of the tire valve.Re-check the tire pressure withthe tire gage.Be sure to put the valve capsback on the valve stems. Theyhelp prevent leaks by keepingout dirt and moisture.Tire Pressure forHigh-Speed Operation{ WARNINGDriving at high speeds, 160 km/h(100 mph) or higher, puts anadditional strain on tires.Sustained high-speed drivingcauses excessive heat build upand can cause sudden tire failure.You could have a crash and youor others could be killed. Somehigh-speed rated tires requireinflation pressure adjustment forhigh speed operation. Whenspeed limits and road conditionsare such that a vehicle can bedriven at high speeds, make surethe tires are rated for high speedoperation, in excellent condition,and set to the correct cold tireinflation pressure for the vehicleload.Vehicles with P235/65R18,P235/55R20, or 235/55R20 size tiresrequire inflation pressure adjustmentwhen driving your vehicle at speedsof 100 mph (160 km/h) or higher. Setthe cold inflation pressure to themaximum inflation pressure shownon the tire sidewall, or 44 psi(300 kPa), whichever is lower. Whenyou end this high-speed driving,return the tires to the cold tireinflation pressure shown on the Tireand Loading Information label. SeeVehicle Load Limits on page 8-12and Tire Pressure on page 9-49.You will find the maximum load andinflation pressure molded on thetire's sidewall, in small letters, nearthe rim flange. It will read somethinglike this: Maximum load690 kg (1521 lbs) 300 kPa (44 psi)Max. Press.srx.book Page 51 Monday, June 8, 2009 8:28 AM
