Design of 9.00-20NHS 14PR OB502 Industry Vehicle Tire

The design of 9.00- 20NHS 14PR OB502 industry vehicle tire was described. In the structure design, the following parameters were taken： overall diameter 1 006 mm, cross-sectional width 232 mm,width of running surface 210 mm,arc height of running surface 5. 5 mm, bead diameter at rim seat 514 mm,bead width at rim seat 178 mm,maximum width position of crosssectional（HI/H2 ） O. 921 9, transverse block pattern, pattern depth 25 mm, block/total ratio 76 %,and total number of pitches 30. In the construction design, the following processes were taken： three-formula and four-piece extruded tread,8 layers of high strength 1400dtex/3 nylon 6 dipped cord for carcass ply,and 2 layers of 1400dtex/3V3 nylon 6 dipped cord for breaker ply. The tires were built on turn up bladder and cured by using type B bladder curing press. It was confirmed by the test of the finished tires that, the inflated peripheral dimension and physical properties met the requirements in design and national standard.
