INSPECTION



The original equipment tires have built-in tread wear indicators to show when tires need replacement. These indicators will appear as 0.47 in. wide bands when the tire tread depth becomes 0.063 in. When the indicators appear in 3 or more grooves at 6 locations, tire replacement is recommended.

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

If the following conditions are noted, rotate the tires:



Front tire wear is different from rear.
 
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 front tire wear is unequal.
 
Wear is uneven across the tread of any front tire.
 
Front tire treads have a scuffed appearance with feather edges on one side of the tread ribs or blocks.
