An interactive tire wall includes a vertical wall that is formed with a plurality of openings. Tires are mounted in the openings on the vertical wall, and placards are mounted on the vertical wall, in which each placard is adjacent and corresponds to a respective tire. A machine-readable code is formed on each placard and corresponds to a respective one of the tires. The code is capable of being read by an imaging device contained in a portable device that is connected to the Internet. When the machine-readable code is read by the imaging device, data in the machine-readable code directs a browser or a software application stored on the portable device to a web site containing purchasing information for the selected tire. A method of purchasing tires is also provided.
