The structure and construction design on 24 -- 21 16PR sand tire was described. In structure design,the following parameters were taken：overall diameter 1 350 ram, cross-sectional width 605 mm, width of running surface 480 mm, arc height of running surface 45 mm, bead diameter at rim seat 529 ram,bead width at rim seat 457 mm,maximum width position of cross-section （H1/H2） 0.85,longitudinal zigzag tread pattern, and pattern depth 20 mm. In construction design, the following processes were taken： 10 layers of 1870dtex/2 nylon 66 cords for carcass ply, single bead wire ring for bead, Ф1. 0 mm copper-plated tempered bead wire, and using semi-flat building machine to build tires in the order of 4-4-2. The finished tire test showed that the overall dimension and physical performance met the requirements of national standards.
