| The Design on 12R22. 5 18PR radial tire was described. In structure design，the following parameters were taken：overall diameter 1 070 mm，cross-sectional width 310 mm，width of running surface 235 mm，arc height of running surface 7. 5 mm，bead diameter at rim seat 550 mm，bead width at rim seat 250 mm，maximum width position of cross-section（H1/H2） 0. 840，tread pattern with alternated long pattern and short-pattern，pattern depth 17 mm，block/total ratio 73. 6%，and number of pattern pitch 80. In construction design，the following processes were taken：tread with fully layered design，sidewall with three part combination structure，0. 25 ＋ 6 ＋ 12×0. 225HT steel cord for carcass ply，4 ＋ 6×0. 30HT steel cord for 1#，2#and 3# belt，5×0. 35HI steel cord for 4# belt，bead ring with oblique hexagonal structure，using one stage building machine to build tire and dual-mold nitrogen curing process to cure tire. It was confirmed by the finished tire test that，the inflated peripheral dimension，strength property and endurance performance reached the requirements of design and national standards． |
