| Abstract: | The design of the 12.00R20 18PR reinforced all-steel radial truck tire was described. In the structural design： expansion ratio of the outer diameter 1.002, expansion ratio of the section width 1.015, bead diameter at rim seat 508 ram, bead width in rim seat 230 mm, maximum width position of cross section 0.931, mixed tread pattern, block/groove ratio 65.77%, pattern depth 17.5 ram. In the construction design： 3 ＋9 ＋15 × 0.175 ＋0.15 steel cord for carcass ply, 3 layers of regular belts and additional 2 layers of 0° belts for belt ply. The inflated peripheral dimension, strength performance, high speed performance and durability of the finished tire met the design requirements. |
