MICHELIN TIRE LIMITED WARRANTY W A R R A N T Y Always maintain minimum recommended inflation pressures. Never exceed the maximum pressure rating indicated on a tire's sidewall. Use an accurate tire gauge to check pressure. Never allow children to inflate or deflate tires. Failure to maintain correct inflation pressures may result in improper vehicle handling, rapid and irregular tire wear, sudden tire destruction, loss of vehicle control and serious personal injury. Therefore, inflation pressures should be checked at least once a month and always prior to long-distance trips. This applies to all tires - including sealant types, which are as susceptible to losing air pressure as any other type if not properly maintained. Pressures should be checked when tires are cold; in other words, before they have been driven on. Driving, even for a short distance, causes tires to heat up and air pressure to increase. Checking Pressure When Tires Are Hot When tires have been driven for more than three minutes or one mile, pressures will increase by approximately 4 psi. Therefore, when adjusting tire pressures under these conditions, add 4 psi to the recommended cold-inflation pressure. For example: Gauge reading of hot tire: Recommended cold-inflation pressure: Add 4 psi to recommended cold-inflation pressure: Air pressure to add to hot tire: 32 psi 30 psi 34 psi 2 psi Check cold-inflation pressures as soon as possible, at least by the next day. Bleeding air from hot tires may result in underinflation. High Speed Correct inflation pressure is especially important when driving at high speed. However, even when tires have correct inflation pressure, road hazards are more 70 Y o u r W a r r a n t i e s i n D e t a i l
