Businesses that support Automotive Service Excellence (ASE) and employ ASE-certified technicians subscribe to the Code of Responsible Automotive Servicing Practices and the ASE-Certified Technicians' Code of Ethics.

These standards require vehicle repair and service shops to maintain the finest quality auto repair services in the industry every time. ASE Technicians provide first-class workmanship, are continually learning, provide honest services, and always work in the best interest of the customer.
As a business that supports ASE and employs ASE-certified automotive technicians, discount tire retailers such as Belle Tire subscribe to the Code of Responsible Automotive Servicing Practices, such as:
- Recommend corrective and car maintenance services and explain to the customer which services are required now to correct existing problems and which are for preventive maintenance
- Offer customers a price estimate for work to be performed
- Obtain prior authorization for all work done, in writing or by other means satisfactory to the customer
- Keep customers informed about appointments and completion deadlines
- Provide an itemized invoice for parts and services, fairly priced, which clearly identifies any used or remanufactured parts
- Inspect replaced parts with customer upon request
- Supply copies of any warranties covering parts or services
There are more than 350,000 professionals that hold ASE certifications who work in every part of the automotive service industry. Qualified individuals who work for tire retailers have advanced experience working on vehicle suspensions, braking systems and alignment. ASE mechanics have the knowledge to diagnose and repair a variety of issues with the highest standards to get you back on the road.
