Terms of the transaction, which was finalized late last week, were not disclosed. Sun Tire founder Dick Erickson is no longer associated with the business, a Mavis spokesman said.
Sun Tire operates nine stores in Jacksonville and two in Tallahassee. The stores will continue to operate under the Sun Tire name for the foreseeable future, a spokesman said.
The deal is Mavis' third acquisition in Florida this year. In January it closed a deal to buy Kauffman Tire Inc.'s retail business—57 stores in Georgia and 12 in Florida.
Mavis itself is in the process of merging with Express Oil Change & Tire Engineers, a deal that will create a group with more than 870 locations in 24 states along the East Coast and throughout the South and Midwest.
