So I originally thought what a great idea and bought 4 tires (with $50 rebate), had them shipped to installer. Initially impressed. Then tires started losing air, one drastically to the point of twice weekly inflation. Received rebate card, it was good for 6 months and not accepted anywhere, then expired. Tirebuyer is not sending new card, not accepting responsibility for the deflating tires. Nothing. I'm disgusted with their lack of customer service. Their abilty to screw a client.
