GM Canada New Vehicle Tire Warranty
Program
The tires supplied with a new vehicle are covered by
General Motors against defects in material or
workmanship under the New Vehicle Limited Warranty
(Base Warranty Coverage).
For vehicles within this warranty period, defective tires
will be replaced on a pro rata adjustment basis
according to the following distance-based schedule:
• 0-19,000 km: 100% of the replacement tire value
is covered by GM
• 19,001-60,000 km: The customer contributes to
the cost of tire replacement based on vehicle
odometer reading. A proration system is used, with
customer participation increasing incrementally as
the vehicle odometer reading increases. See the
applicable proration table below for details.
• 60,001-80,000 km: Coverage continues on Buick
(2022 and Prior) and Cadillac models only with the
customer responsible for 80% of replacement tire
cost.

Copyright 2024 General Motors. All Rights Reserved.

This proration is based solely on vehicle odometer
reading. Tread depth measurements and/or seasonal
tire usage are not pertinent for the purposes of this
calculation and are NOT REQUIRED for GWM Transaction submission.
Note: If the tire is not in stock and the vehicle is
returned to the Customer while the tire is being
shipped, the vehicle distance at the time the tires were
ordered must be recorded on the Job Card and used to
determine the proration amount. Any additional accrued
vehicle odometer reading between ordering and installation should not be charged to the Customer.
Important: Proration applies to the price of the “tires”
only. Cost plus warranty mark-up must be calculated
before determining the prorated amount. No labour
charges are to be assessed to the Customer for tire
replacement. GM will cover 100% of the cost for labour
(mount and balance tires) for tires replaced under the
Base Warranty Coverage, based on published allowances in the Labour Time Guide.

Tire proration policies and percentages also apply to
tires replaced under Customer Enthusiasm, and tires
replaced that were damaged as a result of a
warrantable vehicle component.

Customer
Participation

A 2021 Chevrolet vehicle with 29,733 km requires
one tire be replaced. The full cost of the tire
including handling allowance is $156.20. In this
example, the Customer Participation is 50% of the
tire replacement cost calculated as follows:
$156.20 x 50% = $78.10. GM will cover the
remaining portion for the tire ($156.20 - $78.10 =
$78.10) and 100% of the labour to mount and
balance the new tire.

•

A 2022 Buick vehicle with 23,994 km requires
both front tires to be replaced due to a
warrantable condition. The full cost of each tire
including handling allowance is $172.72. In this
example, the Customer Participation is 40% of the
tire replacement cost calculated as follows:
$172.72 x 2 tires = $345.44 x 40% = $138.18. GM
will cover the remaining portion for the tires
($345.44 - $138.18 = $207.26) and 100% of the
labour to mount and balance the new tires.

•

A 2020 Cadillac vehicle with 67,593 km requires
one rear tire to be replaced. The full cost of the
tire including handling allowance is $215.46. In this
example, the Customer Participation is 80% of the
tire replacement cost calculated as follows:
$215.46 x 80% = $172.37. GM will cover the
remaining 20% of the tire replacement cost
($43.09) and 100% of the labour to mount and
balance the new tire.

What is Covered
• Original Equipment (OE) tires and PDI installed
Limited Production Option (LPO) tires.
Note: Most OE and LPO tires will have a Tire
Performance Criteria (TPC) number molded on the
sidewall near the tire size.
• Tires replaced under warranty will continue to be
covered for the remaining portion of the Base
Warranty Coverage. Proration tables should be
applied based on the distance accumulated from
the time of the installation of the replacement tire,
through the end of the vehicle’s Base Warranty
Coverage term.

What is Not Covered
• Non-Original Equipment tires (excluding dealerreplaced tires under the New Vehicle Limited
Warranty).

Manual for tire care policies while vehicles are in
dealer inventory.

• Cold weather cracking on high performance
summer tires. Refer to the latest version of Service
Bulletin #13-03-10-001 for further details.
• Some tire weathering and superficial cracking is
normal. Tires must not be replaced under the New
Vehicle Limited Warranty for this condition.

Examples of Non-Warrantable Tire Conditions
Tires replaced under warranty for non-warrantable
conditions are subject to charge back. Inspection of
tires replaced under warranty reveals that the most
frequent non-warrantable condition claimed is road
hazard, followed by improper wear. The following are
photos of actual returned tires that DO NOT have
warrantable conditions and a subsequent chargeback
(debit) was processed after inspection.

• Tires on a vehicle after the Base Warranty
Coverage expires. Original Equipment tires may
still have prorated warranty coverage by the tire
manufacturer once the Base Warranty Coverage
expires.
• Tires purchased by consumers (summer, allseason or winter), including Customer Pay tires
that are sold through GM Customer Care and After
Sales/Service, are warranted by the respective Tire
Manufacturer. Claims must be made directly with
the appropriate tire manufacturer.
• Normal tire wear.
Important: Tire wear greatly varies by both the tire type
installed and the driving habits of the owner. OEM tires
installed on GM vehicles are evaluated for many
different criteria and may have been selected to
optimize handling, ride quality, load carrying or traction
demands. Different types of tires will experience
different rates of wear, resulting from all of the above
factors. No warranty is offered on the usable tread life
of the tires.
• Uneven wear from damaged, worn or misaligned
suspension components.
• Road hazard (punctures, cuts, impact breaks, etc.
Important: Road hazard may be covered by certain
Tire Manufacturers on specific tires.
• Damage resulting from driving with low tire
pressures.
• Damage resulting from improper tire repairs.
• Damage resulting from extended driving on a flat
tire. (Except Run-Flat and Self-Sealing Tires)
• Damage due to misuse, negligence, lack of
maintenance, alteration, racing and vandalism.
• Flat spotting caused by parking a vehicle for an
extended period of time. See Article 2.1.2 of the
Transportation, Vehicle Storage and PDI Policy

1967355

The tire shown above has two non-warrantable conditions. This tire is both badly worn on the inside shoulder
(over extended mileage) and has suffered air leakage
from a screw still in the tread.

Bulletin No.: 22-NA-106

1967352

This tire was returned for air leakage. The source of the
air leakage is a tire plug installed in a non-approved
portion of the tire. This tire has been damaged by a
road hazard and does NOT exhibit a warrantable
condition.

This tire was damaged by extended driving with little or
no air, just as the tire above it was. This photo shows
the inside view. Shredding of the inside may not always
be accompanied by obvious exterior damage.

1967361

This final example of common road damage is called a
“rim-pinch”. The air leak is caused by the tire folding
and contacting the rim. Frequently this type of damage
will cause a sidewall bulge when the tire is inflated, due
to internal cord breakage. It is common for this type of
damage to only be visible from the inside of the tire.
The pictured tire is properly marked and shows a
typical tear in the cord.

2034306

The above tire shows sidewall wear extending
completely around the tire. This damage is the result of
extended driving on a tire that is completely flat. The
extensive sidewall wear is from contact with the road at
that point. Minor indents on the sidewall of the tire are
caused from the manufacturing splices in the tire. They
are normal and do not negatively impact the
performance of the tire. Refer to the latest version of
PIT4261 for further details.

GM Inflator Kits/Tire Pressure Monitor Sensors
ONLY use the tire sealant included with GM Inflator Kits
for temporary repair of tire air leaks. General Motors
has tested this sealant and its compatibility with onwheel mounted tire pressure monitor sensors. After
inflator kit use, the wheel mounted tire pressure sensor
should be inspected for any damage, and replaced/
cleaned as needed.

Some tire weathering and superficial cracking is
normal. Tires should not be replaced under the New
Vehicle Limited Warranty for this condition.
Minor indents on the sidewall of the tire are caused
from the manufacturing splices in the tire. They are
normal and do not negatively impact the performance
of the tire. Refer to the latest version of PIT4261 for
further details.

Tire Rotation and Care
Please advise customers of the importance of regular
tire rotations and maintaining the specified air pressure
for their tires. Vehicle Owner Manuals contain tire
rotation requirements. Placards located in the door
jamb, glove box or under the trunk lids of GM vehicles
state the recommended tire pressures for the vehicle.

Use of GM Tire Sealant
GM may recommend/endorse practices that differ from
those of individual tire manufacturers. One example is
