Operation Tires and wheels Maximum tire inflation pressure Always follow the recommended tire inflation pressure ( page 311) for proper tire inflation. 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. 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 Maximum permissible tire inflation pressure i For illustration purposes only.
