Design of 235/60R18 107T Winter Passenger Car Radial Tire

The design of 235/60R18 107T studded winter passenger car radial tire was described. In the structure design ,the following parameters were taken: overall diameter 735mm, cross-sectional width 249mm, width of running surface 192.7mm, height of running surface 6.4mm, bead diameter at rim seat 457.6mm, bead width at rim seat 198.12mm and cross-sectional level ratio(H1/H2) 1.04, adopting special tread pattern TR757 for studded winter tire with optimized pitch arrangement. It was designed with finite element analysis technology, reinforced sidewall and 2 polyester 1300D/2 DSP for body ply with high turn-up, 3*0.30HT steel cord for belts, wrapped rectangle bead, using single stage building machine to build tires and double cavity hydraulic curing presses. Finished products performance tests showed that peripheral dimensions, plunger test performance, bead unseating resistance, endurance, low inflation pressure and high speed performance of the tire all met national standards and company standards.
