| The design of 43×16.0R20 tubeless aviation radial tire was introduced.In the structure design，the following parameters were taken：overall diameter 1 045 mm，cross-sectional width?370 mm，width of running surface 290 mm，arc height of running surface 290 mm，bead diameter at rim seat?505 mm，bead width at rim seat?340 mm，maximum width position of cross–section（ H/1/H/2）?1.11，using 4 longitudinal grooves tread pattern，pattern depth?8.0 mm，pattern width 6.0 mm.In the construction design，the following processes were taken：using specialized tread compound with high tensile stress at a given elongation，adding adhensive rubber sheet for belt and an aramid cord corrugated protective layer under the tread，using 14-layer 920dtex aramid cord＋2300dtex nylon 66 cord for belt，using 6-layer 2100dtex/3 nylon 66 cord for carcass，using circular section steel bead ring，using a special two-stage building machine to build tire and a steam pot dual-mode vulcanizing machine to cure tire.The inflated peripheral dimention，physical properties，burst performance，static load performance and dynamic performance of fineshed tire all met the design and national standard requirements. |
