If you are dissatisfied with your tires within 30 days of purchase, under certain circumstances, you may be able to replace your tires with another set purchased from BJ's.
The Tire Center at your local club can explain your options to you. All return requests due to "buyer's remorse" are evaluated on a case-by-case basis.
If your tires are defective or you experience covered damage to your tires, you may be eligible for replacement or a prorated credit toward the purchase of new tires under the terms of BJ's Road Hazard Warranty.
