Big O Tires is one of North America's largest retail tire franchisors, with more than 450 independently owned and operated locations extending through 23 states primarily in the Western and Midwestern United States.^[1] It has been a wholly owned subsidiary of TBC Corporation since 1996.

In a landmark case in 1977, Big O Tires was awarded $19.6 million from Goodyear over Goodyear's use of the name "bigfoot" tires. The amount equaled 25% of Goodyear's advertising budget in the states where Big O operated. The amount was reduced on appeal and the case was later settled.^[3]
