Conditions Covered By Tire Manufacturer's Warranty

The tires supplied on a Hyundai vehicle are covered against defects in material or workmanship under the tire manufacturer's warranty.

This section provides information on conditions that may be covered by the tire manufacturers' warranties. Review this section and the tire manufacturers' warranty booklets. If you have any questions, please consult the tire manufacturers' distributors for specific details.

1. TREAD SEPARATION





Partial or complete separation between the rubber and the tire cord or between the layers of the tire cord.

Observation(s):

Check for a bulge on the tire shoulder and a longitudinal crack on the bottom of the grooves, possibly accompanied by a break through the rubber surface. Both are usually accompanied by localized wear in the tread above the separation.

Prevention:

^ Maintain proper inflation pressure

^ Avoid overloading

^ Drive at a moderate speed

^ Avoid sharp cornering

2. GROOVE CRACKING





Fine longitudinal cracks commonly found in the tread groove base. These cracks do not penetrate into the cord material of the tire. If the tire continues to be used in this condition, the cracks may join together and may sometimes extend as far as the carcass. Cracking growth is also increased in underinflated tire conditions.

Observation(s):

Check other tires on the vehicle for this condition. If there are only one or two cracks in the tire groove or if the crack continues up the side of the groove wall, the cause of the crack is a cut inflicted by a road hazard condition and in that case, the tire is not warrantable.

Prevention:

^ Maintain proper inflation pressure

^ Avoid overloading

^ Remove stone pick-up in the tread grooves

3. SIDEWALL SEPARATION





Localized separation of the sidewall rubber and ply cord or between the plies can occur as shown below. This condition often times appears as a bulge or bubble and may be felt by hand or with a probe.

Observation(s):

Check tire for proper inflation and observe the tire for absence of scuff marks, abrasion or chafing on the immediate area of damage.

Prevention:

^ Maintain proper inflation pressure

^ Avoid overloading

^ Drive at a moderate speed Avoid sharp cornering

4. OPEN SPLICE





A localized detachment of the rubber stock between the block and sidewall caused by a lack or loss of adhesion where the rubber stock is joined. An open splice may be a partial opening or a complete detachment and total perforation to the interior

Observation(s):

There should be no evidence of cuts or perforations in the open splice area. The open splice usually displays a smooth angular skive.

Prevention:

^ Maintain proper inflation pressure

^ Avoid overloading

Observation(s):

Check for tine cracks on the tire sidewall. These cracks are generally less than 1/10th of an inch in length and do not penetrate to the interior of the tire.

Prevention:

^ Store tires properly; keep tires away from direct sunlight, ozone sources, heat, wind, rain, etc.

^ Maintain proper inflation pressure

^ Avoid overloading

5. SIDEWALL CRACKING





Fine cracks on the tire sidewall, running in a radial or circumferential direction. This type of crack may develop on the tire sidewall from ozone in the atmosphere acting on the rubber. To replace a tire with this condition, refer to tire manufacturer's warranty booklet.

Observation(s):

Check for fine cracks on the tire sidewalk. These cracks are generally less than 1/10th of a inch in length and do not penetrate to the interior of the tire.

Prevention:

^ Store tires properly; keep tires away from direct sunlight, ozone sources, heat, wind, rain, etc.

^ Maintain proper inflation pressure

^ Avoid overloading

6. BEAD AREA CRACKING





Separation of various tire materials (rubber, cord and wires) at the bead area near the rim line. Some of these can occur as a result of bead flow, pinched bead or improper assembly of the tire.

Observation(s):

Check tire for a bulge and/or jagged cracks visible near the rim fitting line. Sometimes the cut may not be visible when the tire is mounted on the wheel.

NOTE:
If the bead rubber is torn as a result of mis-assembly of the tire to the wheel by the assembly plant, coverage is related to the limited new vehicle warranty and not to the tire manufacturer

Prevention:

^ Maintain proper inflation pressure and avoid overloading

^ Avoid excessive speed and sudden braking

^ Match tires with rim properly and mount tires according to proper procedure

7. INNERLINER SEPARATION





Separation appears as a bulge inside the tire. This condition usually occurs between inner rubber and carcass ply.

Observation(s):

Vehicle vibration, a difficult to balance wheel or ride quality conditions may result from inner liner separation. To confirm this condition, the tire has to be dismounted. A bulge in the rubber may be visible or can be confirmed by lightly pressing with fingers on the bulged rubber.

Prevention:

^ Maintain proper inflation pressure

^ Avoid overloading

^ Drive at a moderate speed Avoid sharp cornering
