| TThe design on high performance wide base 385/65R22.5 all-steel radial tire was described.During the designing，experience design and simulation analysis were used to optimize the mold profile and pattern pitch arrangement，and the tread was applied with low rolling resistance compound which had good wear resistance.In structure design，the following parameters were taken：overall diameter 1 070 mm，cross-sectional width 392 mm，width of running surface 300 mm，arc height of running surface 14.5 mm，bead diameter at rim seat 572 mm，bead width at rim seat 324 mm，maximum width position of cross-section（H1/H2） 1.058，4 longitudinal zigzag grooves pattern with variable pitch design for tread，pattern depth 16 mm，the number of pattern pitches 3，and block/total ratio 78.5%.In construction design，the following processes were taken：built-in double compound structure for tread，four layers structure for belt，3×0.20＋6×0.35HT steel cord for 1# belt，3＋8×0.33HT steel cord for 2# and 3# belt，5×0.35HI steel cord for 4# belt，0.25＋6＋12×0.225HT steel cord for carcass，using three-drum building machine to build tire and B type turnover double mold curing press to cure tire.It was confirmed by the finished tire test that，the inflated peripheral dimensions，strength performance，endurance performance and high speed performance were good，the rolling resistance was grade B，the passing noise was class A，and the snow performance reached the level of special snow tire. |
