We instruct our suppliers to only supply us with tires that have current DOT dates. If you receive a tire with a DOT date of more than 4-years from the date of purchase, you may return it and we will pay the return shipping costs and waive the restocking fee. For any tires with a DOT date less than 4-years from date of purchase, you may return it, but you must pay the return shipping costs and restocking fee. Any tire that has been mounted is NOT eligible to be returned.
