Irregular and / or Premature Wear Description
Irregular and premature wear has many causes. Some of them are: incorrect inflation pressures, lack of tire rotation, driving habits, improper alignment.
If the following conditions are noted, rotation is necessary:
• Front tire wear is different from rear.
• Uneven wear exists across the tread of any tire.
• Front tire wear is unequal between the right and left.
• Rear tire wear is unequal between the right and left.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if the following conditions are noted:
• Front tire wear is unequal between the right and left.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with “feather” edges on one side of tread ribs or blocks.
[A]: Hard cornering, under inflation or lack of tire rotation
[B]: Incorrect wheel alignment, tire construction not uniform or wheel heavy acceleration
