REAR TIRE WEAR
This bulletin supersedes Technical Bulletin WT85-006 and WT87-001. Please reference this bulletin in the respective Technical Bulletin books.
APPLIED MODELS:
1984-1986 Sentra and 1983-1986 Pulsar NX, SERVICE INFORMATION
Some 1984-1986 Sentra and 1983-1986 Pulsar NX vehicles may exhibit unusual rear tire wear patterns. There are two different types of tire wear (Type
A and Type B). An incident vehicle may exhibit either or both types.
Type A
Type A tire wear is best described as smooth, even wear on the outside shoulder of the tire, and the wear may be unequal on right and left tires. The
following factors will increase the rate of Type A tire wear:
1.
Low or uneven tire pressure.
2.
Abrasive road surfaces.
3.
Frequent high vehicle loads.
4.
Rear toe-in near the specification limit.
Type B
Type B rear tire wear is best described as a diagonal scrub pattern with cupping. This irregular rear tire wear is caused by a combination of the
following:
1.
Excessive rear tire/wheel imbalance or tire non-uniformity.
