Design on 295/60R22.5 Low Profile All-steel Truck and Bus Radial Tire
The design on 295/60R22.5 all-steel truck and bus radial tires with low profile was introduced.In the structural design,the following parameters were taken:overall diameter 922 mm,cross-sectional width 294 mm,width of running surface 246 mm,arc height of running surface 9.5 mm,bead width at rim seat 248 mm,bead diameter at rim seat 569.5 mm,maximum width position of cross-section(H1/H2)0.9155,using 4-longitudinal pattern grooves.In the construction design,the following processes were taken:using coextruded tread compound,4+3×0.33ST steel cord for 1# belt,3+8×0.33HT steel cord for 2# and 3# belts,5X0.30HI steel cord for 4# belt,3 × 0.24+9 × 0.225CCST steel cord for carcass,using one-stage building machine to build tires and hot plate vulcanizing press to cure tires.The test results of the finished tire showed that,the inflated peripheral dimension,strength,durability and high-speed performance met national standards and design requirements.
