Over or under inflated tires can affect vehicle handling and tread wear. This may cause the tire to fail suddenly, resulting in loss of vehicle control.Under inflation will cause rapid shoulder wear (1), tire flexing, and possible tire failure.

Over inflation will cause rapid center wear (1) reduction in the tire's ability to cushion shocks.Improper inflation can cause:Uneven wear patternsReduced tread lifeReduced fuel economyUnsatisfactory rideVehicle driftFor proper tire pressure specification refer to the vehicles Owners Manual.
