Li Shijun;Wu Suhua;Yinchuan Giti Tire Co., Ltd.;School of Materials Science and Chemical Engineering, Tianjin University of Science and Technology;  
The design of 195/60R15 88H passenger car radial tire is presented in this paper. In the structural design, the parameters are as follows: tire overall diameter 614 mm, cross sectional width 212 mm, width of running surface 160 mm, bead diameter at rim seat 379 mm, bead width at rim seat 178 mm, maximum width position of cross section(H 1 /H 2) 1.03, 4 longitudinal main groove pattern, and pattern block ratio 63.4%. In the construction design, three formula and four piece tread is applied, one layer of 1670dtex/2 dimensionally stable polyester cord is used in carcass ply, and two layers of 2+2×0.25HT steel cord and one layer of 930dtex/2 nylon 66 cord are applied in the belt layer. The tire is built by using two stage tire building machine and cured on B-type vulcanizing machine. The experimental test results on the finished tire show that the strength performance of the tire and the bead unseating resistance meet the requirements of national standards, and the durability and high-speed performance meet the requirements of enterprise standards.
