2) Claims would be  given to whatever damage caused by tire manufacturing quality problems.  

2. Tire Quality  Claim Identification Terms

2.1 Crown: Tire  Tread

2.1.1 Crown  separation: no trauma and impact, crown rubber and belt are separated.  

2.1.2 Pattern groove  cracking: pattern groove base of tire without mechanical damage is cracked; the  belt can be seen if serious.

2.1.3 Open joint:  transverse rubber of crown is separated from rubber with a certain slope.  

2.1.4 Tread rubber  layer up: partial tread rubber of crown fall off layer by layer, there is rubber  powder or rubber block.

2.2 Shoulder:  position from crown edge to kerbing rib

2.2.1 Shoulder  separation: shoulder rubber is separated from rubber, or rubber is separated  from belt, but no obvious protuberance, no scar on surface of separation point,  no tear, and no damage on inner surface of separation point.

2.2.2 Shoulder  split: there is cracking between shoulder rubber and rubber in peripheral  direction, surface of cracking point is smooth, no trauma, with a certain slope  and depth, the belt can be seen if serious.

2.2.3 Shoulder  separation and blow out: there is no tear, mechanical damage and crash, no  damage on inner surface of tire inside.

2.3 Side part:  position from shoulder kerbing rib to chafer fitting line

2.3.1 Sidewall  delaminating: side rubber is separated from carcass, no trauma on outer  surface.

2.3.2 Side bubble:  there is air bubble between side rubber and carcass, which causes  separation.

2.3.3 Side split:  there is cracking between side rubber and rubber in radial and circumferential  direction, no damage by hard objects.

2.3.4 Side bloat:  cord of radial tire is sparse; the side bloats in radial direction during  inflation.

2.4 Tire cavity:  inner surface between two bead toes

2.4.1 Separation:  crown, shoulder is separated from inner liner caused by some factors except  overload.

2.4.2 Exposed cord:  steel cord in tire cavity is exposed partly, which causes some effects including  assembly and usage of inner tube, air tightness of tubeless tire.

2.4.3 Cavity  separation: there is separation between inner liners, which affects air  tightness of tubeless tire.

2.4.4 Open joint of  inner liner: joint of inner liner is cracked, which affects air tightness of  tubeless tire.


III. What Isnt  Covered

3.1 Damaged tires  caused by abnormal usage and improper using in early phase.

3.2 Tires as  unofficial product grade to sell (including the tire with unclear serial number:  if the serial number is not clear before using, it should be given claims. Then  punish the related department or principal after the tire returns; if the serial  number is unclear caused by wearing or disappeared with other causes after  using, it cannot be given claims).

3.3 Retreaded  tire.

3.4 Tires that the  quality defects, identification (including size identification), ply rating and  tire serial number is forged.

3.5 Tires repaired  by client (including there is/no causal relationship between repaired position  and defect position).

3.6 Tires damaged by  improper usage causing the following problems:

3.6.1 Crown blow  out: crown blow out regularly.

3.6.2 Overloading  shoulder separation: shoulder is separation in circumferential direction, more  than 1/4 perimeter.

3.6.3 Crown damage:  rough tread rubber, block fall off.

3.6.4 Uneven wear:  single side of crown is wore quickly (the difference of pattern depth on both  sides is over 3mm, or the residual pattern depth on uneven wear side is less  than residual pattern depth for no claims).

3.6.5 Crown wear:  serious wear on middle part of crown.

3.6.6 Deformity  wear: crown is worn in the shape of wave and saw tooth.

3.6.7 Zipper blows  out: sidewall blow out in zipper-like circumferential direction or radial  direction.

3.6.8 Wear bead toe:  the chafer wear out caused by insufficient pressure or unfit rim, chafer is  exposed if serious; the carcass steel cord is cracked between bead toe and  sidewall (bead break off).

3.6.9 Bead  deformation: bead area is damaged, or steel cord of bead is deformed.  

3.6.10 Bead blow  out: bead area blow out in circumferential direction caused by higher pressure,  overload or crooked tire assembly.

3.6.11 Bead  cracking: bead area is cracked in circumferential direction caused by higher  pressure, overload or crooked tire assembly.

3.6.12 Sidewall  damage, carcass ford break or deformation caused by insufficient  pressure.

3.6.13 Other  problems are caused by improper usage.

3.6.14 Mechanical  damage problem are caused by external factor. Crown  scratch: crown is scratched trimly; the depth goes to belt cord. Crown  puncturing: crown is punctured by sharp objects (there is obvious mechanical  damage mark, there is regular cut on wound), which causes the belt and carcass  cord on puncture point to be cracked and separated, the tire would blow out if  serious. Shoulder  trauma: shoulder is scratched or punctured by barrier, rough wound, and no  separation on wound. Split  aperture: carcass is cracked in radial direction, as a result sidewall or crown  run into sharp objects in the condition of high speed. Side  trauma: sidewall is cut or wore by sharp objects (cause the steel cord on  sidewall to be broken), no separation. Bead  damage: improper operation during tire assembly period, the bead chafer is  broken; the bead lip of tubeless tire is broken.

3.7 Some problems  beyond claims scope identified by plant technician.


IV. Force  Majeure

Even if we try our  best, there are still problems with tires due to various reasons, so we could  not control all the problems, and under the following circumstances, claims  wouldnt be offered:

4.1 Natural  disasters, e.g. typhoon, flood, earthquake, etc.

4.2 Government  action, e.g. expropriation, requisition.
