| The design of 775/65R29 ☆☆ E-3 low-section OTR radial tire was described. In the structure design, the following parameters were taken: overall diameter1735mm, cross-sectional width776mm,width of running surface 658.76mm, height of running surface 36.5mm, bead diameter at rim seat 727.8mm, bead width at rim seat 622.3mm, maximum width position of cross-section(H1/H2)0.82, cross-country tread pattern, pattern depth 46mm, block/total ratio 58.5%. In the construction design, the following processes were taken: wrap tread and base tread, 3+9+15*0.245HT steel cord for carcass ply, 7×7×0.22＋0.15HT steel cord for 1# and 2# belt ply, 3×7×0.22HE steel cord for3# and 4# belt ply; using semi-stage building machine to build tire and press mold to cure tires. It was confirmed by the tests of finished tire that, the peripheral dimension and endurance performance and TKPH met the requirements of national standard. |
