| In this paper，the design of 295/75R22.5 14PR tubeless TBR tire was presented.In the structure design，overall diameter was 1 010 mm，cross-sectional width was 308 mm，width of running surface was 220 mm，arc height of running surface was 9 mm，bead diameter was 571 mm，bead width was 254 mm，maximum width position of cross-section（H1/H2） was 0.84，four longitudinal groove structure was used，tread depth was 17.2 mm，number pattern pitch was 84，block/total ratio was 73.4%.In the construction design，two formula and two block tread structure was applied，3＋9×0.22＋0.15HT steel cord was used in carcass，3×0.20＋6×0.35HT steel cord was adopted in the 1# and 2# belt layers，3×4×0.22HE steel cord was used in 3# belt layer，and 3×7×0.20HE steel cord was applied in 0° belt layer. The tire was built using single stage building machine and cured with steam curing press.It was confirmed by the test of finished tires that the inflated peripheral dimension and strength performance of the tire met the requirements of national standards，and the endurance performance and high speed performance met the requirements of enterprise standards. |
