Design of 225/45ZR17 94W XL Ultra-high Performance Passenger Car Radial Tire
The design of 224/45ZR17 94W XL ultra-high performance passenger car radial tire was introduced.In the structure design,the following parameters were taken:overall diameter 626 mm,cross-section width 234 mm,width of running surface 191mm,arc height of running surface 8 mm,bead diameter at rim seat 435.2 mm,bead width at rim seat 206 mm,maximum width position of cross-section(H1/H2)0.95,adopting asymmetrical pattern design with 4 longitudinal grooves,pattern depth 8 mm,block/total ratio 70.5％,and number of pattern pitches 72.In the construction design,the following parameters were taken:two layers of 3×0.28ST ultra-high strength steel cord for belt,two layers of 1100dtex/2 enhanced polyester cord for carcass,using a one-stage building machine to build tires and a vulcanizing press to cure tires.The finished tire performance test results showed that the inflated peripheral dimension,strength,bead unseating resistance,high-speed performance and durability all met the corresponding design and national standards,and the tire's comfort,dry and wet handling performance,dry and wet braking distance were comparable to those of competitors.
