Abstract:
      The design on 245/70R19.5 16PR all-steel truck and bus radial tire was described.In structure design，the following parameters were taken：overall diameter?837.7 mm，cross-sectional width?256.2 mm，width of running surface　192 mm，arc height of running surface　10 mm，bead diameter at rim seat?493.3 mm，bead width at rim seat?215.9 mm，maximum width position of cross–section（H1/H2）?1.03，pattern depth?13 mm，block/total ratio?77.5%，and number of pattern pitches?77.In construction design，the following processes were taken：using hot and cold feed co-extruded tread，using 4 layer construction for belts，3×0.20＋6×0.35HT steel cord for 1#—3# belt，5×0.30HI steel cord for 4# belt，3＋9×0.22＋0.15HT steel cord for carcass ply，Φ1.83 mm bead wire for bead，using three-drum one stage building machine to build tire and double-mold B-type hot-plate curing press to cure tire．It was confirmed by the finished tire test that，the inflated peripheral dimension，strength and endurance met the requirements of the design and national standards.
