| The design on 7.50-16 8PR forestry tire was described.In structure design,the following parameters were taken:overall diameter 806mm,cross-sectional width 194mm,width of running surface 180mm,arc height of running surface 8mm,bead diameter at rim seat 405mm, bead width at rim seat 152mm,maximum width position of cross-section (H1/H2)0.798,design of extra deep block pattern ,pattern depth 16.5mm,number of pattern pitches 26,and block/total ratio 72%.In construction design,the following processes were taken: The tread adopts the cold feed extruder extrusion, the carcass ply of 4 layers of 1400 dtex / 3 nylon 6 cord was used. Using bag anti - bag forming machine, hydraulic capsule curing press cure. It was confirmed by the tests of the finished tire test that,the inflated peripheral dimension and corresponding performance met the requirements of the design. |
