Costco Road Hazard Warranty

To qualify for this warranty:

You must be the original purchaser of the tires.
You must have purchased the tires from Costco Wholesale.
You must present the original purchase receipt and tire to a Costco Wholesale tire center.

Conditions of this warranty:

You must rotate and balance your tires as outlined by the vehicle manufacturer.
You must operate your tires at inflation pressures outlined by the vehicle manufacturer.
You must keep all mechanical parts that affect tires in proper working condition.
You will be required to sign a "Costco Wholesale tire adjustment form".

What is covered:

"Road hazard failure" is defined as a tire that becomes unserviceable due to cuts, non-repairable punctures or impact damage. Costco Wholesale will repair tires with treadface injuries in accordance with established USTMA (United States Tire Manufacturers Association) standards.
This warranty covers road hazard failures in most passenger, performance and light truck tires purchased from Costco Wholesale. The warranty may not be available for certain vehicles and/or tires – please contact the Tire Center for details.
For greater certainty, this warranty only covers the specific tire that is damaged/failed due to road hazard failure. This warranty does not provide credit for the other tires on a vehicle that are not damaged/failed due to road hazard failure.
This warranty is valid for 60 months from the date of purchase, or until the tire reaches 1.6 mm Millimetre (2/32 of an inch) or less in remaining tread depth regardless of age, whichever occurs first. When a tire has 1.6 mm Millimetre (2/32 of an inch) or less in tread depth, it is considered worn out and this warranty does not apply.
This warranty provides credit based upon remaining usable tread at the time of failure due to road hazard.
"Usable tread" is defined as the original tread depth of a tire less than 1.6 mm Millimetre (2/32 of an inch).
Credit is determined by multiplying the usable remaining tread by the price you paid for the tire net of all discounts received.
This warranty is a promise under certain conditions to give credit on a prorated basis towards the purchase of a new tire. This warranty does not imply that tires sold by Costco Wholesale meet certain specifications or cannot fail. This warranty does not replace or modify any original tire manufacturer’s warranty on material and workmanship.

What is not covered:

A tire that is damaged/failed due to vandalism.
A tire that is damaged/failed due to an accident.
A tire that is damaged/failed due to commercial use.
A tire that is damaged/failed due to racing.
A tire that is damaged/failed due to off-road use.
A tire that is damaged/failed due to snow chains or studs.
A tire that is damaged/failed due to rapid or irregular wear.
A tire that is damaged/failed due to wear from worn or improperly - adjusted or -maintained mechanical components on the vehicle.
Tires transferred from the vehicle on which they were originally installed.
Loss of time, inconvenience, loss of use of vehicle or consequential damage except where and to the extent prohibited by law.
A tire that does not meet the definition of "road hazard failure" above.

Tire care recommendations:

Have the air pressure in your tires checked by a tire professional as least once a month. Serious injury may result from tire failure due to under- inflation.
Always request that the air pressure in your tires be set to the tire or vehicle manufacturer's specifications.
Do not overload your vehicle. Serious injury may result from overloading your vehicle.
Register your tires using the DOT (Department of Transportation) card provided at the time of installation.
Read and follow all tire maintenance requirements outlined in the tire manufacturer's warranty booklet provided at the time of installation.
Always insist on USTMA (United States Tire Manufacturers Association) approved two-piece tire repair if required.
Fix-a-flat products should be avoided if possible. These products can make a tire non-repairable.
If you are purchasing less than four tires, mount the new tires on the rear of the vehicle.
It is recommended to have your lug nuts re-tightened 40 km / 25 miles after your tires are serviced or replaced.
Request that your tire and rim assemblies are hand-torqued with a calibrated torque wrench to the vehicle manufacturer’s specifications.
