pressure is adjusted under these conditions, it should be increased to a gauge reading of 4 psi greater than the recommended cold inflation pressure. For Example Only: Gauge reading of hot tire:...32 psi (220 kPa) If recommended, cold inflation pressure is: ...30 psi (205 kPa) Desired gauge reading of hot tire 30 + 4 psi = 34 psi (205 + 30 = 235 kPa) Therefore: add 2 psi ...(15 kPa) Check cold pressure as soon as possible, preferably within 24 hours. "Bleeding" air from hot tires could result in under inflation. Use an accurate tire gauge to check pressures. Never allow children to inflate or deflate tires. Always make certain valve caps are installed on all tire valves to keep out dirt and moisture. TIRE SPINNING Do not spin wheels in excess of 35 mph (55 km/h) as indicated on the speedometer. Excessive speed in a free-running, unloaded tire can cause it to "explode" from centrifugal force. The energy released by such an explosion is sufficient to cause serious physical injury or death. Never allow anyone to stand near or behind the spinning tire. When in mud, sand, snow, ice or other slippery conditions, do not engage in excessive wheel spin. Accelerating the motor excessively, particularly with automatic transmission vehicles, may cause a drive tire that has lost traction to spin beyond its speed capability. This is also true when balancing a drive tire/wheel assembly on the vehicle using the vehicle engine to spin the tire/wheel assembly. HIGH SPEED DRIVING CAN BE DANGEROUS Correct inflation pressure is especially important. However, at high speeds, even with the correct inflation pressure, a road hazard for example is more difficult to avoid and if contact is made, has a greater chance of causing tire damage than at a lower speed. Moreover, driving at high speed reduces the reaction time available to avoid accidents and bring your vehicle to a safe stop. 53

it to “explode” from centrifugal force. The energy released by such an

When in mud, sand, snow, ice or other slippery conditions, do not engage
