Water guiding and blocking device for preventing water splashing of tyres

A water guiding and blocking device for preventing water splashing of a tyre comprises a flanging, an end splashing prevention bar and a water guide groove. The flanging is located on the outer side circumference of the tyre and is an annular rib protruding in the radial direction. A horizontal plane flanging upper edge is arranged on the upper surface of the flanging, a flanging lower edge is arranged on the lower surface of the flanging, and an arc-shaped water guide face is arranged on the lower edge of the flanging. A water guide groove and the end splashing prevention bar are arranged at the outer end of the water guide face. The water guiding and blocking device is located on the outer side surface of the tyre or symmetrically located on the outer side surface and inner side surface of the tyre. The water guiding and blocking device can effectively reduce the speed of tyre water splashing and reduce the included angle of the water splashing and the ground, and especially at a high speed, it still can be guaranteed that the included angle of water splashing and the ground is small. The water guiding and blocking device is also suitable for tyre water splashing control of vehicles in water accumulated road surfaces.
