英文摘要:
      The design of medium and long-distance 425/65R22.5 20PR 165K truck and bus tire was described.In the structure design，the following parameters were taken：overall diameter　1 122 mm，cross-sectional width?420 mm，width of running surface　332 mm，arc height of running surface　10 mm，bead diameter at rim seat?569.58 mm，bead width at rim seat?336 mm，maximum width position of cross–section（ H/1/H/2）?0.96，adopting 5 continuous grooves pattern for tread，pattern depth?18 mm，block/total ratio?74.97%，and number of pattern pitches?46.In the construction design，the following processes were taken：using a fully layered design for tread，using 3×0.2＋6×0.35HT steel cord for 1#—3# belt，using 5×0.35HI steel cord for 4# belt，using 0.25＋6＋12×0.225HT steel cord for carcass，using oblique hexagonal structure for bead，using a one-stage three-drum building machine to build tires and a flat vulcanizing press to cure tires.The results of the finished tire performance test showed that，the inflated peripheral dimention，strength and durability met the requirements of corresponding design and national standards.
