Damage caused by cutting by foreign objects

Check your tires regularly for any damages and ensure the right tire pressure. If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection, repair or replacement.

Tread damage caused by cutting by foreign objects

Check your tires regularly for any damages and ensure the right tire pressure. If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection, repair or replacement.

Tread damage caused by cutting by foreign objects

Please avoid impact against foreign objects (e.g. pot holes on the road) whenever possible. Slow down if the road condition is poor. Maintain correct tire pressure. If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection, repair or replacement.

1) Repeated cutting by foreign objects (e.g. fender, certain parts on chassis or obstacles on road surface)
2) Using tire chains in winter may cause the problem, too.

If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection, repair or replacement.

Under-inflation (under-inflation not only consumes too much fuel, also causes tire damage)

Check your tires regularly for any damages and ensure the right tire pressure. If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection, repair or replacement.

Over-inflation (over-inflation also may stretch the ply too much and make it easy to break during an impact).

Ensure the right tire pressure and check your tires regularly for any damages. If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection, repair or replacement.

Incorrect camber and toe-in/toe out

If damages as shown are found on your tires, please go to Michelin tire shops immediately for wheel alignment.

Vehicle camber setting is incorrect.

If damages as shown are found on your tires, please go to Michelin tire shops immediately for wheel alignment.

Incorrect vehicle alignment settings

If damages as shown are found on your tires, please go to Michelin tire shops immediately for wheel alignment.

Excessive localized wear caused by hard braking

Avoid extreme driving maneuvers like hard braking. Check tread wears regularly. If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection.

Puncture to the sidewall area by a foreign object or poor repair after puncture

Check tire pressure regularly and request that Michelin approved repair methods are used. If damages as shown are found on your tires, please go to Michelin tire shops immediately for inspection.

Casing plies rupture due to impacts of tire shoulder or upper sidewall by foreign objects (e.g. pot holes or curb).

Replace with spare wheel immediately (because the casing ply has been damaged) and go to a Michelin tire shop for thorough inspection.

Sidewall is cut by foreign objects (completely)

Replace with spare wheel immediately (because the tire ply has been damaged) and go to a Michelin tire shop for thorough inspection.

Sidewall is cut by foreign objects (not through)

Replace with spare wheel immediately (because the internal construction may have been damaged) and go to a Michelin tire shop for thorough inspection.

Caused by cut

Replace with spare wheel immediately (because the internal construction may have been damaged) and go to a Michelin tire shop for thorough inspection.

Continuous driving with flat tire breaks sidewall and detaches it from the tire.

Slow pressure loss caused by puncture; poor repair after puncture; rubber cracks around the valve; poor combination between tire and wheel; misalignment of valve or valve core.

Check tire pressure regularly. When air leaks are found, go to a Michelin tire shop immediately for trouble-shooting.

Caused by continuous driving with a pressure lower than required ot carry the load (lower-right photo). If driving continues, the sidewall will detach from the tire completely.

Slow pressure loss caused by puncture; poor repair after puncture; poor combination between tire and wheel; misalignment of valve or valve core

Check tire pressure regularly. When air leaks are found, go to a Michelin tire shop immediately for trouble-shooting.

Poor balance, poor alignment or mismatch of vehicle steering system and suspension

1) After mounting new tires or having a tire repaired, ensure that the wheel and tire assembly are correctly balanced (correct balance provides comfortable ride and extended tire life; poor balance may cause driver fatigue, excessive or uneven tire wear and damages to the suspension system).

2) Balance your tires when vibration is found. If the vibration continues after balancing, the steering system, suspension and alignment must be checked to find the cause.

Poor wheel alignment

Check wheel alignment to ensure even wear and precise driving.

Alignment is a must when you find:
1) Uneven wear on front and rear tires
2) Changes in vehicle handling or steering reactions (e.g. the vehicle goes left or right side)

If the suspension system and steering system works correctly and the wheel rolls in a straight line, the wheel alignment is correct. When the suspension system puts the tires on the ground evenly, the tire wear will be even, too.
