Proper tire inflation is an important safety function that needs to be precisely followed. Properly inflated tires can most certainly help to promote better fuel economy. Regular care helps tires get the most potential wear so they don’t need to be replaced as often.
It’s important to have the proper inflation pressure in your tires, as under inflation can lead to tire failure. The “right amount” of inflation for your tires is specified by the vehicle manufacturer and is shown on any of the following places: the vehicle door edge; door post; glove box door; or on the fuel door (see image below). It is also listed in the vehicle owner’s manual. Check inflation pressure at least once a month and before long trips. Check tires when cool – driven tires need at least 3 hours to cool. Visually inspect the tires to make sure there are no nails or other objects embedded that could poke a hole in the tire and cause an air leak. Check the sidewalls to make sure there are no gouges, cuts, bulges or other irregularities. Do not forget to do the same on your spare tire.
Under inflation or overloading creates excessive stress and heat, and can lead to tire failure. This could result in vehicle damage and/or serious injury or death. Over inflation can make the tire more susceptible to road hazard damage and pose vehicle handling issues.
