Process was very smooth. Ordered tires on June 2, received them via FedEx on June 10. Outstanding! Appreciated the emails I received with order status and tracking numbers.

Quality parts at a good price. Fast delivery. Only reason I did not give five stars was that the parts were not packed securely, and the one package broke open and lost one of the nuts that go to the muffler clamp. Now I have to buy another muffler clamp from the auto parts store. Besides that I was very satisfied with my experience.
