Conditions Not Covered By Tire Manufacturer's Warranty

Normal tire wear or wear out is not covered. Road hazard damage such as punctures, cuts, snags and breaks resulting from pothole impact, curb impact or from other objects, is not covered. In addition, damage from improper inflation, spinning (as when stuck in mud or snow), tire chains, racing, improper mounting or dismounting, misuse, negligence, alteration, vandalism, or misapplication is not covered.

This section provides information on the types of conditions not covered by the tire manufacturers' warranties. Review this section and the tire manufacturer's warranty booklet. If you have any questions, please consult the tire manufacturer's distributor for specific details.

1. SUDDEN OR EXCESSIVE FORCE CRACK OR BREAK





Crack or break in tire interior surface. This may be caused by sudden and excessive force applied to the tire exterior which exceeds reinforcing material limits.

2. TIRE CORD BREAK





A severe side impact can cause the tire cord to break. This can result in a bulge in the sidewall when inflated.

To confirm this condition, look for any scrapes or scratches at or near the bulge, a bent rim flange, or a pinched/cut inner liner.





NOTE:
The above condition should not be confused with sidewall indentations.

3. RUN FLAT





Another example of a road hazard occurs when a tire is grossly under-inflated. This causes the tire to overheat and eventually deteriorate into a run flat condition.

Prevention:

^ Maintain proper inflation pressure Avoid sudden air loss

4. SIDEWALL CHUNKING





Sidewall may chunk oft as shown. This may be caused by improper installation of a tire chain.

5. TREAD CHUNKING





Pieces of rubber may be torn or chunked out of tire's tread. This chunking may occur during vehicle testing on Dynamometer rolls.

The running condition causing chunk out on a roll test is different and much more severe than conditions encountered during over the road driving.

6. IRREGULAR WEAR





Uneven wear patterns may be caused by improper inflation pressures, misalignment, improper balance or suspension component damage. It should be suggested to customers that they inspect their tires closely for signs of uneven wear at least once a month.

7. CAMBER or TOE WEAR





Camber or Toe wear indicates misalignment due to misadjusted, loose, worn or bent steering linkage components, or spring fatigue which causes the vehicle's body to ride closer to the road.

8. SHOULDER WEAR





Under inflation can result in premature wear of both outer edges.

Preventions:

^ Keep proper air pressure in the tires

^ Checking wear patterns of tires regularly

9. CENTER WEAR





Over inflation can result in premature wear of center section of the tire.

Prevention:

^ Keep proper air pressure in the tires

^ Check wear patterns of tires regularly

10. CUPPING WEAR





If tires have not been rotated according to schedule, irregular wear, cupping, and tire noise may result.

11. BRAKE LOCK-UP





Brake lock-up can damage localized areas of the tire.

12. FLAT SPOTTING

Vehicle with flat spotted tire(s) may shake/vibrate at low speeds.

Causes of flat spot:

a. Long shipping period of vehicle with a low air pressure condition in the tires.

b. Keeping the vehicle in storage without change in the parking position.
