The design of 14.9-26 10PR R-2 agricultural tire was introduced in this paper. In the structure design, the overall outer diameter was 1370 mm, the width of cross section was 360 mm, the width of running surface was 349 mm, the bead diameter at rim seat was 664 mm, the maximum width position of cross section (H1/H2) was 0.522 , the tread depth was 73 mm, the block to total ratio was 21%, and the number of pattern pitches was 17. In the construction design, two formula and three piece tread was extruded, 4 layers of 2200dtex/2V1 high tenacity nylon cord and 2 layers of 2200dtex/2 nylon cord were used in the breaker ply and carcass ply, respectively, andΦ1.0 mm tempered steel wire was used in the bead. The tires were built on aΦ860 mm building machine and cured by using a vertical autoclave. The inlfated peripheral dimension and physical properties of the ifnished tires met the requirements in national standards.
