Design of 15.0/55-17IMP 14PR Low Profile Tubeless Agricultural Tire

The design of 15. 0/55- 17IMP 14PR low profile tubeless agricultural tire was de- scribed. In the structural design, the following parameters were taken： overall diameter 792 mm, cross-sectional width 378 mm, width of running surface 315 ram, height of running surface 17 ram,bead diameter at rim seat 434 ram,bead width at rim seat 343 ram,maximum width position of cross section （H1/H2） 0. 835 9,6 longitudinal zigzag grooves, pattern depth 11 ram,total number of pitches 34, block/total ratio 63%. In the construction design, the following processes were taken：two formula and three-piece extruded tread,4 layers of dipped 2100dtex/3 nylon 6 cord for car- cass ply;using bladder turn-up building machine to build tires,and using 45 inch bladder curing press 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 standard, the static load per- formance met the application requirement.
