Operation Tires and wheels Maximum tire inflation pressure Warning! Uniform Tire Quality Grading Standards (U.S. vehicles) Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resistance. G Never exceed the max. tire inflation pressure. Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. 1 Maximum permissible tire inflation pressure i For illustration purposes only. Actual data on tires are specific to each vehicle and may vary from data shown in above illustration. This is the maximum permissible tire inflation pressure for the tire. Always follow the recommended tire inflation pressure ( page 569) for proper tire inflation. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. 1 Treadwear 2 Traction 3 Temperature resistance i For illustration purposes only.
