Good tires are a necessity for every car owner, and the U.S. had more than 254 million registered cars in 2008, according to the Bureau of Transportation. This makes a tire business a potentially lucrative endeavor. To be successful, you need a knowledge of vehicle and wheel types, new and used tires, tire rotation and flat tire repair.

Enroll in the "Commercial Tire Service" course through the Tire Industry Association to become a certified tire repair technician. Train to remove, install and repair tires. Learn road service safety and Occupational Safety and Health Administration (OSHA) guidelines. For tire repair services, hire a mechanic that is Automotive Service Excellence (ASE) certified.

Contact your state's Environmental Protection Agency (EPA) office for an inspection of your tire repair business. You may be required to draft a site plan showing runoff prevention, methods to contain oil and chemical spills and proper tire storage. Obtain a waste tire permit.

Contact tire-recycling businesses in your area to recycle unsalvageable aluminum, steel and tires.

Buy or lease a tow truck and offer to pick-up or remove cars that have flat tires. Put your business name and phone number on the side of the truck for potential new customers to see.

Advertise your tire repair service online. Include information about recycling companies you work with and how they reuse the tires or break them down for rubber.
