In fact, misalignment and improper inflation are probably the two biggest causes for tires wearing out prematurely. If you're driving on the highway and you loosen your grip from the steering wheel for just a second , an improperly aligned vehicle is likely to start edging to one side or the other rather than maintaining a straight line. Causes for misalignment include aggressive cornering, hard braking or bumping a curb.
Alignment involves adjusting the wheels to certain specifications so they track in a straight line.
To avoid damaging your tires, and to make sure the alignment problem doesn't continue getting worse, it's important to correct the situation as soon as possible. When your mechanic performs an alignment, several factors are checked. If the tops of the wheels angle in toward the vehicle, this is referred to as negative camber. If the tops angle away from the vehicle, it is a positive camber. When properly adjusted, the camber angle keeps the outside tires flat and stable on the ground during a turn.
