I started using Dobbs last Fall. Their store at the Promenade in St. Louis was so helpful with a tire pressure sensor issue that I had while I was in St. Louis. They didn't even charge me for putting on my spare tire. I bought a set of new tires from this location in Waterloo last November. Since then I've had to have repairs done twice. A nail and them something cut into the tire on my way home from work. Both were emergency repairs. They got me right in and fixed the flats and didn't charge me a dime since I had purchased the tires from them. Very happy with this business.
