All tire's come with some sort of basic warranty directly from the manufacturer. Here are the two most common:
Manufacturer's Defect Warranty:
All products sold to you by TireGet are guaranteed by a manufacturer’s warranty to be free of defects in workmanship and materials. This warranty is extended to the first retail purchaser only and can be obtained directly from the manufacturer of the tire you've purchased. If your tire has a defect covered by the manufacturer’s warranty, you will receive a pro-rated credit for the unused portion of the tread based on your original purchase price.
Original Treadlife Warranty:
Some products from manufacturers offer a treadlife warranty which can be located directly from the manufacturer. To provide a successful case on the original treadlife, please save your installation, rotation, and purchase records of your tires to submit to the manufacturer.
