Irregular and/or Premature Wear






Irregular and premature tire wear has many causes. Some of them are: incorrect inflation pressures, lack of regular rotation, driving habits, or improper alignment. If wheel alignment is reset due to tire wear condition, always reset toe as close to zero degrees as the specification allows.

Rotate the tires if the following conditions are noted:
^ Front tire wear is different from rear.
^ Uneven wear exists across the tread of any tire.
^ Left and right front tire wear is unequal.
^ Left and right rear tire wear is unequal.

Check wheel alignment if the following conditions are noted:
^ Left and right side tire wear is unequal.
^ Wear is uneven across the tread of any tire.
^ Tire treads have a scuffed appearance with "feather" edges on one side of the tread ribs or blocks.
