These shipped faster than I could believe. None of the stores locally had any. The shipping is excellent, cost, packaging and quality. I liked the first shipment so well I ordered two more.
Service from Miller Tires was great with shipping done in just two days. If I needed something else, would not hesitate ordering from them..nice people.
