The “TR number” refers to the code number assigned by the Tire and Rim Association (TRA) to tube valves and flaps used in tires. These TR numbers serve as identifiers for specific types of valves and flaps and are used by manufacturers, retailers, and consumers to ensure compatibility and proper selection when replacing or installing these components in tires.
Each TR number corresponds to a particular size, shape, and function of tube valves and flaps, helping to standardize their specifications across the industry. This standardization simplifies the process of selecting the appropriate valve or flap for a given tire application, ensuring safety, performance, and compatibility.
By referencing the TR number specified by the TRA, tire professionals can quickly identify the correct tube valve or flap for a particular tire size and type, facilitating efficient installation and maintenance procedures.
