TIRE DIAGNOSTIC PROCEDURES
DESCRIPTION:
The purpose of this bulletin is to provide information about materials and workmanship related types of tire damage and their coverage under warranties.
When a customer returns a tire for inspection and adjustment, refer to the information in this bulletin to help identify causes of damage to tires.
There are three categories that can be used to guide tire replacement warranty coverage. They are:
^
Tire workmanship or material detect - Tire Manufacturer's Warranty
^
Road hazard, customer abuse or non-warrantable vehicle mechanical concern - Customer' Responsibility
^
Warrantable vehicle mechanical condition - Hyundai Warranty
Sometimes the cause of tire damage is immediately apparent. In other cases however, only a thorough inspection of the tire will allow determination of
the cause and whether the damage is eligible for replacement under the tire manufacturer's warranty. Thorough inspection requires good lighting, a clean
dismounted tire and close examination of the inner and outer tire surfaces. Finding a point of penetration can sometimes be very difficult and should be
done on a tire spreader.
THINGS YOU SHOULD KNOW ABOUT THE TIRE MANUFACTURER'S WARRANTY:
HANKOOK AND KUMHO TIRES.
^
Hankook and kumho tire manufacturers' warranty coverage include a provision which allows the customer to go to either an authorized Hyundai
dealer or to the Hankook or Kumho tire dealer (as applicable) for tire warranty service. This provision allows for tire warranty service at the first
point of customer contact.
MICHELIN TIRES
^
Michelin tire manufacturer's warranty coverage requires the customer to go to a Michelin tire dealer for tire warranty service.
NOTE:
This TSB is limited to Hankook, Kumho and Michelin tire warranties.
Tire Glossary
BEAD:
The part of the tire that is constructed to hold the tire securely to the rim. It is made of high tensile steel wires wrapped in woven fabric and secured
within the ply ends.
BELT:
Narrow strips of fabric, fiberglass or steel cords running in a circumferential direction immediately under the tread in the crown of a tire (between the
tread and casing plies). They constrict the plies to provide the tire with high lateral stiffness, and act to help the tire resist deformation in its footprint,
and thus give more effective braking and traction. The belts also protect the air chamber against punctures.
CARCASS:
The tire body beneath the tread and sidewalls; also called casing.
CORD:
The strands of material forming the body plies or belt plies of the tire. Cords may be made from aramid, fiberglass, rayon, nylon, polyester or steel.
DOT MARKINGS:
A code molded into the sidewall of a tire signifying that the tire complies with U.S. Department of Transportation safety standards. The DOT code
includes an alphanumeric designator which can also identify the tire's manufacturer, production plant, date of production and brand.
