| In this paper，the design of 60×25.00－25 50PR coal mining OTR tire was presented.In the structure design，overall diameter was 1 515 mm，cross-sectional width was 625 mm，width of running surface was 520 mm，arc height of running surface was 6 mm，bead diameter at rim seat was 629 mm，bead width at rim seat was 495 mm，maximum width position of cross-section（H1/H2） was 0.794 8，mixed asymmetric tread pattern and large block design were used，and number of pattern pitch was 16.In the construction design，tread was molded by winding process，20 layers of high strength 1870dtex/2 nylon 66 cord were applied in the carcass ply，4 layers of 1400dtex/2 nylon 66 cord were applied in the breaker ply，and three-ring structure and large apex were used for bead.The tire was built using turn-up bladder and cured using type-B curing press.It was confirmed by the test of finished tires that the inflated peripheral dimension and physical properties of the finished tire met the design requirements. |
