| This paper introduces a design of 385/65R22.5 20PR wide base tubeless TBR tire.In the structure design，the following parameters were taken： overall diameter 1068 mm，cross-sectional width 390 mm，width of running surface 286 mm，arc height of running surface 10.2 mm，bead diameter at rim seat 569.5 mm，bead width at rim seat 324 mm，maximum width position of cross section 0.8566，tread pattern with main longitudinal grooves and small transverse grooves，variable pitch design，and block/total ratio 72.6.In the construction design，two formula and two piece structure was applied for tire crown，tri-layer composite structure was selected for the sidewall，0.25+6+12×0.225HT steel cord was adopted in the carcass ply，3+8×0.33HT steel cord was used in 1# and 2# belt layers，3×4×0.22HE and 3+9×0.22+0.15HT steel cord were applied in the 3# and 0°belt layers，respectively，and hexagonal bead wire structure was used in the tire bead.The tire was built on single stage building machine and then cured on curing press under nitrogen.It was confirmed by the test of the finished tires that the inflated peripheral dimension，strength performance and endurance performance met the requirements of corresponding design and national standard. |
