Design on 315/80R22.5 Tubeless All-steel Truck and Bus Radial Tire with High Driving Performance
The design of 315/80R22.5 tubeless all-steel truck and bus radial tire with high driving performance was introduced.In the structural design,the following parameters were taken:overall diameter 1 093 mm,cross-section width 314 mm,width of running surface 275 mm,arc height of running surface 7.585 7 mm,bead diameter at rim seat 570.5 mm,bead width at rim seat 240.8 mm,maximum width position of cross-section(H1/H2)0.91,using mud+snow pattern for tread,pattern depth 24 mm,block/total ratio 66.41％,and number of pattern pitches 54.In the construction design,the following processes were taken:using double compound tread,0.37+6X0.32ST steel cord for 1# and 2# belt,3×0.7×0.20HE steel cord for 0° belt made from 3 pieces of steel cord calendered crown strip wrapping around 2# belt,5X5.30HI steel cord for 3# belt,0.22+6+11×0.205ST steel cord for carcass,using one stage building machine to build tire and dual mold steam press to cure tire.The performance test results of the finished tire showed that the inflated peripheral dimension,strength performance,durability performance,and bead durability performance of the tire met the corresponding design and standard requirements.
