摘　　要：In this paper,the natural rubber is chosen as the main constituents for the transition layer of all-steel load radial tyre,which is pre-vulcanized by 500-keV E-beam irradiation of up to 60 kGy.The results show that the green strength of transitional layer increases with the dose,reaching four times as much as the control(without irradiation) at 60 kGy.The final mechanical properties do not differ significantly from those of the control except that the aging and fatigue performance increased.However,thickness of the natural rubber transitional layer for an average single tyre can be reduced by 1 mm(or 1.5 kg) without obvious adverse effect on tyre performance.In this paper, the natural robber is chosen as the main constituents for the transition layer of all-steel load radial tyre, which is pre-vulcanized by 500-keV E-beam irradiation of up to 60 kGy. The results show that the green strength of transitional layer increases with the dose, reaching four times as much as the control （without irradiation） at 60 kGy. The final mechanical properties do not differ significantly from those of the control except that the aging and fatigue performance increased. However, thickness of the natural rubber transitional layer for an average single tyre can be reduced by 1 mm （or 1.5 kg） without obvious adverse effect on tyre performance.
