Regardless of which hand tools are used, generous amounts of bead lubricant during the demount process are necessary to make the process easier. Likewise, the mounting process requires lubricant on the bead and rim surfaces to help ensure the beads are not damaged and the tire is seating concentrically.
It’s also important to note that more and more tire service providers are starting to explore the usage of tire changing machines when demounting and mounting wide base singles. Undoubtedly there is an increased time factor when compared to hand tool methods, but the wear and tear on technicians is going to add up over time if these assemblies become even more popular and shops continue to service them by hand.
From the inflation standpoint, special restraining devices are necessary since the standard models are not wide enough to accommodate wide base singles. While OSHA regulations allow a single piece assembly to be inflated on the vehicle if the lug nuts are fully tightened, the Rubber Manufacturers Association inspection guidelines for potential zipper ruptures recommends that all tires returning to service be inflated in a restraining device so both sidewalls can be inspected.
The Tire Industry Association (TIA) is an international association representing all segments of the tire industry, including those that manufacture, repair, recycle, sell, service or use new or retreaded tires, and also those suppliers or individuals who furnish equipment, material or services to the industry. TIA was formed by the July 2002 merger of the International Tire & Rubber Association (ITRA) and the Tire Association of North America (TANA).
