Design of 11R22.5 16PR TBR Tire

The design of 11R22.5 16PR TBR tire was described.In structure design,the following parameters were taken：overall diameter 1 058 mm,cross sectional width 286 mm,width of running surface 215 mm,height of running surface 7.2 mm,bead diameter at rim seat 571 mm,bead width at rim seat 235 mm,cross-sectional level ratio（H1/H2） 1.006,with the design of all-season pattern,pattern depth 22 mm,block/groove ratio 62.46%,number of pattern pitch 59.In construction design,the following processes were taken：3×0.24/9×0.225＋0.15HT steel cord for carcass ply,4 layers 3×0.20＋6×0.35HT steel cord for belt ply;using double-drum single stage building machine to build tires,and using B-type double-mold curing press to cure tires.It was confirmed by the tests of finished tires that the inflated peripheral dimension,strength and endurance performance met the requirements in the design and national standard,and speed performance met the requirement in the enterprise standard.
