Denvir Tire is located on Route One in Old Saybrook. Any time that I have had problems with my tires, they have been so helpful and professional, and I find them to be very trustworthy. They provide full tire services from patching a flat to providing rotation or new tires. They specialize in foreign and luxury cars.
Even when I have gone to other tire stores, I find that Denvirs prices are competitive, and they provide 100% better service in a timely manner.
