SAE J1098-2018 PDF

Scope: This SAE Standard establishes the procedures for the application of Tonne Kilometer Per Hour (TKPH) rating values for off-the-road tires; utilizing empirical data formula@ it describes the procedure for evaluating and predicting off-the-road tire TKPH requirements as determined by a work cycle analysis. The loads@ speeds@ inflations@ and rim configurations are assumed to be within acceptable industry or manufacturer's prescribed recommendations. 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 maximizes desirable TKPH characteristics will sometimes compromise these other parameters. The standards for the productivity of off-the-road machines or tires are not included in the scope. The formulae (4.2 and 4.3) are applicable to transport type machines only (that is@ trucks@ tractor trailers@ and scrapers) using Category E Earthmover Service Code Tires. See SAE J751 for service codes.
