| Abstract: | The design of 405/70-24 14PR EMR1 versatile wide tire was described.In the structure design,the following parameters were taken:overall diameter 1121mm,cross-sectional width 402 mm,width of running surface 380 mm,arc height of running surface -4 mm,bead diameter at rim seat 611 mm, bead width at rim seat 330 mm,maximum width position of cross-sectional (H1/H2) 0.746,pattern depth 28 mm,block/ ratio 41.4%,and total number of pitches 22.In the construction design, the following processes were taken:the two-formula and three-piece extruded tread,6 layers high 2100dtex/2 nylon 66 cord for carcass ply ,2 layers of 1400dtex/2 nylon 66 cord for break ply, and using autoclave with the building drum diameter of 575 mm,and using vertical curing pot to cure tires. It was confirmed by the tests of finished tires that the inflated peripheral dimension and physical properties met the requirements of relative design and national |
