Design of LT325/50R22 122S All-terrain Steel-belted Light Truck and Bus Radial Tire
The design of LT325/50R22 122S all-terrain steel-belted light truck and bus radial tire was introduced.In the structural design,the following parameters were taken:overall diameter 882 mm,cross-sectional width 344 mm,width of running surface 284 mm,arc height of running surface 13 mm,bead diameter at rim seat 562.8 mm,bead width at rim seat 274 mm,maximum width position of cross section(H1/H2)1.033,symmetric pattern for tread,main/transverse groove depth 12.7 mm,the ratio of blocks to total 58.66％,and the number of pattern pitches 28.In the construction design,the following processes were taken:two-layer 3+8×0.23ST steel cord ply for belt,three-layer 1440dtex/2 polyester ply for carcass,using two stage building machine to build tire and B-type dual mold shaping and vulcanizing press to cure tire.The finished tire test results showed that the inflated peripheral dimension,strength performance,high speed performance and durability all met relevant standards and development requirement.
