INFORMATION
Isuzu is providing this bulletin to outline Isuzu’s policy and procedures for Isuzu vehicles
with Tire Warranty Coverage.
TIRE WARRANTY
WHAT IS COVERED
For two (2) years, or 24,000 miles (whichever occurs first): If any tire originally equipped
on the truck is defective (please see below what is not covered), the tire will be repaired
or replaced by an authorized tire dealer.
WHAT IS NOT COVERED
The tire warranty does not cover tire wear or damage caused by road hazards, lack of
maintenance, improper use of tire chains, alterations, overloading or vandalism.
POLICY
TIRE SERIAL NUMBER
All tires have serial numbers which are recorded when installed onto a vehicle during
production. In this manner, every tire can be matched to the Vehicle Identification Number
(VIN). Only tire serial numbers associated to a VIN at the time of production are
considered original equipment.
This warranty coverage is for the tires as installed to the original VIN. If any tire is moved
from one vehicle to another, it is considered an alteration and is no longer covered under
the tire warranty.
DETERMINING A DEFECT
Isuzu dealers are not authorized by Isuzu to determine if a tire has failed as the result of
a defect. Only an authorized tire manufacturer representative can make that assessment.
The tire manufacturer representative must inspect the suspected defective tire(s) to make
the determination. If the tire manufacturer representative determines that a tire is not
defective, it will not be covered under the Isuzu tire warranty. Isuzu will only honor
warranty claims for tires that have been determined defective directly by the tire
manufacturer representative.
Dealers are required to follow the procedure below in order to complete the coverage of
the tire warranty. Failure to comply with this procedure will result in claim denial and/or
chargeback.
PROCEDURE
When a tire is suspected to be defective, follow the procedure in this bulletin.
1. Inform the customer that warranty coverage will not be determined until the tire is
deemed defective by an authorized tire manufacturer representative. If it is
determined not to be a defect, all costs will be paid by the customer.
2. Determine the manufacturer of the tire installed onto the vehicle and collect the tire
serial numbers (you may also request this from the tire shop).
a. Bridgestone, Yokohama, Continental, or Dunlop
b. Serial Number (see Figure 1)
Figure 1 – Serial Number Location
3. Sublet the vehicle to the local authorized tire manufacturer facility for tire inspection
and serial number confirmation.
a. For the location nearest to your dealer, please use the store locator at the
appropriate tire manufacturer website.
i. www.yokohamatire.com
ii. www.bridgestonetire.com
iii. www.continentaltire.com
iv. www.dunloptrucktires.com
4. Receive the inspection results from the tire manufacturer representative. Be sure
that the inspection results include the tire serial number.
a. If the tire manufacturer representative determines there is a defect, some
or all of the costs for the tire repair will be absorbed by the tire manufacturer.
Tire manufacturers have varying policies regarding prorated reimbursement
based on remaining useful tire life which may affect the level of coverage
from the tire manufacturer. Any reasonable outstanding balance may be
submitted to Isuzu for reimbursement as a sublet.
b. If the failure is determined NOT caused by a defect, any inspection costs
and repair costs will be the responsibility of the customer.
CLAIM SUBMISSION
For vehicles covered under warranty with a confirmed defect, dealers should use the
information below to submit a claim for any costs not covered by the tire manufacturer.
It is important to keep the original sublet bill (including tire serial numbers) with the claim
paperwork, as it may be required for claim authorization. Dealers can add up to 0.3 hours
of labor for administration of this tire warranty sublet.
