DIAGNOSE – MY TIRES ARE WEARING ABNORMALLY
by Lance Wright
The tires show signs of abnormal wear.
The usual cause of abnormal tire wear is infrequent tire rotations, worn suspension components, or misaligned front end.
The type of tire wear usually indicates the type of malfunction. If the tires are worn only in the middle of the tread area it is an indication of over inflation. If the tires are worn on the outer section of the tread area on both the inside and outside of the tire, it is an indication of under inflation. If the tires are worn on the outside of the tread area on the outside of the tire, it is an indication of improper front end alignment or infrequent tire rotation. For proper tire wear, the tires should be rotated every six thousand miles or every other oil change. If the tires are not rotated frequently, wear on the outside of the tires can result. If the tires have been rotated properly and this type of wear is still present, the alignment of the front end should be checked. Usually the “toe” adjustment will have to be re-adjusted to correct this type of wear. Tires that have peaks and dips accross the tread, it usually indicates worn shocks or struts. Worn shocks or struts will cause excessive tire bounce when going over bumps or dips in the road, which will cause this type of wear.
If the tire wear is caught soon enough they may not require replacement. Frequent tire rotations and proper inflation can go a long way in extending tire life. If the tires have been rotated and inflated properly, the alignment should be inspected by qualified personel using the proper alignment equipment.
PRECAUTIONS, TIPS, and NOTES
Tires contain steel belts that if exposed on a worn or damaged tire, can easily cut your hand. Use extreme caution when inspecting the tires not to run your hand over the tire which may have exposed belts.
