Tire ABC_Tire maintenance

Tire maintenance for motor vehicles is necessitated by several factors. The chief cause of tire failure is friction from moving contact with road surfaces, causing the tread on the outer perimeter of tires to eventually wear away. When the tire tread becomes too shallow, the tire is worn out and should be replaced. The same wheels can usually be used throughout the lifetime of the car. Other problems encountered in tire maintenance include:

  • Uneven or accelerated tire wear: can be caused by under-inflation, overload or bad wheel alignment.
  • Increased wear on a tire facing the outside or the inside of a car: often a sign of bad wheel alignment.
  • Tread worn away completely: especially when the wear on the outer rubber exposes the reinforcing threads within, the tire is said to be bald and should be replaced as soon as possible. 
  • Under-inflation can lead to tire failure. It results in unnecessary tire stress, irregular wear, loss of control and accidents. A tire can lose up to half of its air pressure and not appear to be flat!

It’s important to have the proper air pressure in your tires, as underinflation can lead to tire failure. The “right amount� of air for your tires is specified by the vehicle manufacturer and is shown on the vehicle door edge, door post, glove box door or fuel door. It is also listed in the owner’s manual.
