• This section will provide you with information concerning the various types of tyre damages coming from misusage of tyres. Therefore, the damages listed are not warrantable. A definition of the type of damage along with a photograph of the damage as it appears has been presented.

  • A claim for tyre/tube damage, the causes of which may be proved to be attributable to faulty manufacture only should be accepted. Other damages attributable to improper use will not be considered.
  • In assessing the damage, the final decision after investigation shall be made by representatives authorized by Tyre company.
  • The amount to be compensated will be calculated from the degree of wearing. In other words, the so-called 'Remaining tread depth measurement' system will be applied.
  • Tube replacement will be free of charge.
  • A claim involving any one of the following categories will not be acceptable for compensation.
    1) Damage to tyres/tubes caused by improper use and storage.
    2) Tyres of which tread wear indicators (1.6 mm height) are exposed.
    3) Tubes used for more than one life span.
    4) Tyres that have been repaired or re-capped (inner patch), tyres/tubes that have re-claimed. Tyres once rejected will be branded with letter 'R' on the sidewall or serial number will be buffed off.
    5) Damage from misalignment, wheel imbalance, defective brakes or shock absorbers, improper inflation, overloading, oil or chemical action, fire, use for racing or other competitive events, off-road use, wreck or collision, running flat or willful damage or abuse.
    6) Damage from road hazards.
    Definition: A cut in the tyre tread. Possible Causes & Sources: Caused by sharp objects such as stones, rocks, nails. Recommendation: Drive carefully to avoid cuts to tyre Remove stones, nails etc. from the tyre to prevent them penetrating deeper into the tyre.

    Definition: A sharp cut (in any direction) in the tread shoulder. Additional scratches are usually present around the cut.
    Possible Causes & Sources: Road obstacles such as sharp stones, rocks, nails, etc. Rough driving increases the chance of cutting. Recommendation: Drive carefully to avoid cuts to tyres Inspect tyres regularly-repair damage immediately.

    Definition: Cut (in any direction) in the sidewall with scuffing or abrasion with signs of scuffing or abrasion around the cut area.
    Possible Causes & Sources: Sharp stones, rocks, curbs. Excessive deformation of sidewalls caused by low inflation pressure will increase the chance of cutting.
    Recommendation: Drive carefully to avoid cuts to tyre. Maintain proper inflation pressure.
    Inspect tyres regularly-repair damage immediately.


    Definition: Cut that occurs on the tyre bead-area.
    Possible Causes & Sources: Defective rims (deformed, rusted, cracked etc.)
    Rims of wrong size Improper mounting or de-mounting of rims.
    Recommendation: Inspect tyres & rims frequently. Use proper size of rims. Carefully follow proper mounting/de-mounting procedures.


    Definition: Abnormal wearing appearing on the tread.
    Possible Causes & Sources: Over or under inflation, Defective wheel-alignment.
    Improper matching of tyre & rim Rotation of tyres not properly timed.
    Recommendation: Maintain proper inflation pressure. Match tyres & rims properly.
    Rotate tyres regularly. Maintain proper alignment.


    Definition: Separation between the tread rubber and the card material or between the layers of tyre plies cards.
    Possible Causes & Sources: external cuts, drilling from stones and the like weaken the adhesion between tread rubber and belt cards.
    Recommendation: Drive carefully to avoid cuts to tyre.
    Inspect tyres regularly-repair before damage enlarges.


    Definition: Casing bursting from cuts in the tyre.
    Possible Causes & Sources: External cuts develop to bursting. Excessive inflation pressure, and loads. High speed rough driving.
    Recommendation: Maintain proper inflation pressure and avoid excessive loading.


    Definition: Very small cracks appearing on the sidewalls and tread. (Cracks only on surface, not extending inside.)
    Possible Causes & Sources: Improper storage exposed to Ozone from Sunlight, Generators etc. Long terms storage. Effect of Oxidation (Ozone exposure) maximized by overloading and/or under inflation.
    Recommendation: Store tyres properly: Keep tyres away from direct Sunlight, Ozone, Generators, Heat, Wind and/or Rain. Maintain proper inflation pressure. Avoid excessive loading.
