| The design of AT27×12.00-14 8PR semi-radial all terrain tire was described.In the structure design，the following parameters were taken：overall diameter 670 mm，cross-sectional width 310 mm，width of running surface 274 mm，height of running surface 0 mm，bead diameter at rim seat 352.8 mm，bead width at rim seat 254 mm，pattern depth 20 mm，total number of pitches 20，and block/total ratio 28.5%.In the construction design，the following processes were taken：two-formula and three-piece extruded tread，2 layers of 1400dtex/2 dipped nylon 6 cord for carcass ply，2 layers of 2100dtex/3 dipped nylon 6 cord for breaker ply；bladder turn-up building machine for building tires，and using bladder curing press for curing.It was confirmed by the tests of finished tires that the inflated peripheral dimension，strength performance，endurance performance and speed performance met the requirements of relative design and national standard，and the static load performance met the using requirement. |
