About Magnum Automotive

Magnum Automotive is a locally owned and operated automotive service center founded in 1968. We strive to deliver quality products to our customers. For auto repairs, or new tires and wheels, come see us in person or request a quote online.

Magnum Automotive started out as Jasper County Tire in 1968. In 1982, the name changed to Magnum Muffler and we relocated across the street in our current warehouse. In 1989, we moved next door and expanded to Magnum Muffler and Brake. We then moved to our current location in 2003 and became Magnum Automotive.

We have eight full-time employees with an average of nearly 18 years experience. They help make Magnum Automotive the only AAA-Approved Auto Repair Facility in Jasper County.
