Shopping experience was good, but the picture does not match the item. Leads to confusion.

Great price and quick delivery. The only issue I had was that I did not receive a shipping confirmation and tracking info. I had to contact customer service and they weren't even clear on shipping info. While I was waiting for a reply, the tire showed up at my house. I received shipping confirmation the day after it arrived.

fast and efficient checkout.
