In this paper, the design of 4.50-12 10PR forklift truck tire was described. In the structure design, the following parameters were taken: cross-sectional width 116 mm, overall diameter 546 mm, width of running surface 104 mm, height of running surface 5.5 mm, maximum width position of cross section (H1/H2) 0.8615, bead diameter 304 mm, bead width 76 mm, and tread pattern depth 11 mm. In the construction design, single piece tread with one formula was applied, 4 layers of 1680V1 nylon cord were used in the carcass ply, crown cord angle was set at(54 ± 0.5)°, the cascass safety factor was 12, single steel bead wire was adopted with arrangement of 5×5, and the bead safety factor was 7. The tire was built on semi-drum type building machine while the carcass ply and tread were molded using tube molding process. The testing results showed that the inlfated peripheral dimension and physical properties of the ifnished tire, and the crown cord angle met the design requirements.
