Design of 295/80R22.5 18PR Tubeless TBR Tire

The design of 295/80R22.5 18PR tubeless TBR tire was introduced. In the structural design： overall diameter 1050 ram, cross sectional width 306 ram, bead diameter at rim seat 569.5 ram, bead width in rim seat 254 mm, maximum width position of cross section （H1/H2） 0.965, width of running surface 240 mm, 4-strip vertical pattern, pattern depth 15.0 mm, and block/groove ratio 72.03%. In the construction design： 1 layer of 3 ＋9×0.22＋0.15 HT steel cord for carcass ply, 3 layers of regular belts and additional layer of 0° belt for belt ply; using a single stage building machine to build tires, and using double mold steam vulcanizer to cure tires. It was confirmed by the tests of finished tires that the inflated peripheral dimension, strength performance, endurance performance and high speed performance met the requirements of national standards and enterprise standards.
