RIST is an acronym that stands for the procedure implemented by the Tire Industry Association that institutes precautionary wheel installation steps for tire service. This short phrase was developed to promote safety and accurate procedure within automotive service shops. Following these easy 4 steps will undoubtedly reduce potential error and institute a wheel torque program within your shop.
The first step of the RIST procedure, “R,” entails removing debris from the mating surface. Preparing the mating surface of the wheel is a critical part of the tire balancing process. Wire brushes were at one point the only way to effectively remove rust and corrosion from the wheel mating surface. AME identified this need for a new, innovative tool that would ease the process of removing debris, hence, the Hub Buddy (Part #37330) wheel and stud cleaner was born. The Hub Buddy is a ½” impact-rated tool that fits snugly over a wheel stud and blasts away rust and corrosion within seconds. The Hub Buddy removes all corrosion and rust that your typical wooden-handled brush could not accommodate. Each Hub Hubby comes with one abrasive pad which can be used up to 500 times and replacement pads are available and sold in packs of 6.
The “I” within the RIST procedure stands for the necessary step in which the technician should “Inspect” wheel components. The inspection period will allow technicians to identify any visible issues or signs of damage that could affect the vehicle’s safe operation after service.
“Snug” is the next step of the RIST procedure. This step stands for “snugging the lug nuts in a star pattern to ensure the seating process is equal around the hub. When using an impact wrench, tire service techs should immediately stop applying force when resistance is detected.
“Torque” is the final step, completing the RIST procedure. Technicians should tighten each nut to the recommended torque in a star pattern, taking precaution to ensure the proper amount of pressure is applied.
All tire service technicians should follow the RIST procedure to drastically reduce the chances of a loose wheel or wheel-off accident.Back
