They probably belong to the BBB, but
I have never done business with this store. But I have no doubt the wheels they offer will be exactly what you could get from anyone else in the business. If the price is right, then go for it.
On the other hand, I strongly recommend you do not buy tires from anyone online. If you do, there is a very good chance that the tires sent to you will be very old. Returning something as heavy as four tires will cost money, and it will probably be yours.
Give strong consideration to purchasing tires from a local tire shop. If the tires are too old, it costs you nothing.
