| The design of 45/45R19 E-Controller new energy vehicle tire was described.In the structure design，the following parameters were taken：overall diameter 705 mm，cross-sectional width?204 mm，width of running surface 210 mm，arc height of running surface 7.9 mm，bead diameter at rim seat?480 mm，bead width at rim seat?225 mm，maximum width position of cross–section（H/1/H/2）?1.037，adopting asymmetric pattern distinguishing between inner and outer sides，pattern depth?7.4 mm，and block/total ratio?70.07%.In the construction design，the following processes were taken：adopting a fully layered double-layer tread structure and dual composite sidewall structure，using 2-layer of 2＋2×0.30HT steel cord for belt and nylon 66 cord for crown belt，using 2-layer of 1200dtex/2 polyester cord for carcass，using a one stage building machine to build tire and a hydraulic vulcanizing press to curing tire.The results of finished tire performance test showed that，the inflated peripheral dimention，strength performance，low pressure durability and high speed performance of this design tire met the requirements of design and enterprise，the wet grip performance，rolling resistance and electrostatic conductivity were good，and the noise was low. |
