Design on 225/65R17106T ARCTIC STU99 Snow Tire

The design on 225/65R17106T ARCTIC STU99 snow tire was described.In the structure design,the following parameters were taken:overall diameter 714 mm,cross-sectional width 237 mm,width of running surface 180 mm,arc height of running surface 7.5 mm,bead diameter at rim seat 432 mm,bead width at rim seat 197.8 mm,maximum width position of cross–section(H1/H2)0.9860,alternate pitch design of long pattern(M and L type)and short pattern(S type),pattern depth 10.5 mm,block/total ratio 68.25%,and number of pattern pitches 31.In the construction design,the following processes were taken:layered extrusion was adopted to produce the tread,double compound extrusion was used for the sidewall compound production,nylon 66 cord was applied in the crown belt,3×0.30HT steel cord was adopted for 1#and 2#belt,and high modulus and low shrinkage polyester cord was used for carcass.One-stage building machine was used to build tires,and hydraulic vulcanizing press and nitrogen vulcanization process were applied to cure tires.The test results of the finished tire showed that,the inflated peripheral dimension,strength,durability and high speed performance of the finished tire met the requirements of the corresponding design and enterprise standards.
