Tire Warranty

Determining a Defect

What is Covered

Chevrolet Medium Duty dealers are not authorized by
General Motors 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
General Motors tire warranty. General Motors 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
when administering the GM Tire Warranty. Failure to
comply with this procedure will result in claim denial
and/or charge-back.

For two (2) years, or 24,000 miles (whichever occurs
first) : If any tire originally equipped on the truck is
defective (Please see below for 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 normal tire wear or
damage caused by road hazards, lack of maintenance,
improper use of tire chains, alterations, overloading or
vandalism.

Tire Warranty 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 at the time of production. If any tire is
moved from one vehicle to another, it is considered an
alteration and is no longer covered under the tire
warranty.

Procedure
When a tire is suspected to be defective, follow these
steps:
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 on
the vehicle and record the tire serial numbers (you
may also request this from the tire shop).
3. Sublet the vehicle to the local authorized tire
manufacturer facility for tire inspection and serial
number confirmation.

4. Receive the inspection results from the tire
manufacturer representative. Be sure that the
inspection results include the tire serial number.
• 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 for the repair or
replacement of a defective tire may be
submitted to General Motors for reimbursement
as a sublet up to 2 years or 24,000 miles,
whichever comes first.
• If the failure is determined NOT to be caused by
a defect, any inspection costs and repair/
replacement costs will be the responsibility of
the customer.

Warranty Transaction Submission

tire defect, dealers should use the information below to

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
