| Abstract: |
| The development of the two stage building utility terrain vehicle （UTV） radial tire was
introduced. Based on the analysis of the configuration of sample tyres，28×10R14 UTV radial tire adopted
the structure of carcass ＋ belt ＋ capply，and its specific configuration was：carcass skeleton material
930dtex/2 nylon 66 cord，carcass crown angle 20°，belt skeleton material 930dtex/2 nylon 66 cord，
belt crown angle 65°，cap ply skeleton material 1400dtex/2 nylon 66 cord （one line winding with an
overlapping of 5 mm），steel ring Φ0. 96 mm steel wire with 5×4 arrangement，appex size（height×width）
35 mm×5 mm. The performance of the finished UTV radial tire met relevant requirements. Compared with
the belted bias tire，the peripheral dimension stability and dynamic balance performance of the UTV radial
tire was improved，and the raw materials cost was reduced by 10.76%. |
