This SAE Standard establishes the procedures for the application of Ton Kilometer Per Hour (TKPH)rating values for off-the-road tires; utilizing empirical data formula, it describes the procedure for evaluatingand predicting off-the-road tire TKPH requirements as determined by a work cycle analysis. This document isapplicable to only those tires used on earthmoving machines as defined in SAE J1057, and contains machines referenced in SAE J1116.1.1 The loads, speeds, inflations, and rim configurations are assumed to be within acceptable industry ormanufacturer's prescribed recommendations.1.2 Other application parameters affecting tires are not included in the scope (for example: flotation, cut, bruise,wear, etc.). These parameters must also be considered for final tire selection, since a tire that maximizesdesirable TKPH characteristics will sometimes compromise these other parameters.1.3 The standards for the productivity of off-the-road machines or tires are not included in the scope.1.4 The formulae (4.2 and 4.3) are applicable to transport type machines only (that is, trucks, tractor trailers, andscrapers) using Category E Earthmover Service Code Tires. See SAE J751 for service codes.
