Commonly found on Trucks and Equipment deployed in Construction, Farming, Material Handling, Mining, and related applications, belong to this specialized category. These Off-The-Road (OTR) tyres are systematically classified by the Tyre and Rim Association (TRA). TRA codes for OTR tyres consistently begin with a letter, followed by a number, and sometimes another letter. The initial letter signifies the type of machinery for which the tyre is suitable, while the subsequent digit indicates the tyre’s specific tread depth.
