The appearance of the tire can be misleading. In addition, tire inflation pressure that is even just a few pounds off can degrade ride and handling. l Do not reduce tire inflation pressure after driving. It is normal for tire inflation pressure to be higher after driving. l Never exceed the vehicle capacity weight. Passengers and luggage weight should be placed so that the vehicle is balanced. 508
