Discount Tire is not the same as American Tire. Discount Tire is its own company that specializes in tires and related services, while American Tire is a division of a larger company that sells a variety of automotive products. Both companies have a wide selection of tire brands and types to choose from, but Discount Tire may have more options for customizing your tires or getting specialized services like wheel alignments. In terms of price, both companies are generally competitive, but Discount Tire may offer more sales and discounts throughout the year.
