| The design of 225/45R17 ALL CLIMATE AC-1 high-performance all-season radial tire was described.In the structure design，the following parameters were taken：overall diameter 633 mm，cross-sectional width?241 mm，width of running surface 189 mm，arc height of running surface 6.6 mm，bead diameter at rim seat?434 mm，bead width at rim seat?220 mm，maximum width position of cross–section（H/1/H/2）?1.08，using three grooves tread pattern with a biomimetic V-shaped interlocking pattern，pattern depth?7.4 mm，block/total ratio?70.07%，and number of pattern pitches?61.In the construction design，the following processes were taken：adopting two-layer tread design，using 2-layer belts＋1-layer crown belt design，using 3×0.28ST steel cord for 1# and 2# belt，nylon 66 cord for the crown belt，and 1-layer 1440dtex/2-115 polyester cord for carcass，using a 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 the tire met the design requirements. |
