Description

Multi-nail-hole nail-embedded tire

Technical Field

The invention relates to the technical field of antiskid tires, in particular to a multi-nail-hole nail-embedded tire.

Background

In northern areas of China, Europe and North America, a large amount of ice and snow can cover the road surface in winter, and when the tire runs, a layer of water film can be formed on the road surface with the ice and snow, so that the friction force between the tire and the road surface is reduced, the tire is slipped, and the safety of drivers and pedestrians is greatly threatened. In view of the above problems, nailed tires having good grip and more effective against ice and snow road surfaces are becoming more popular.

Existing studded tires generally include: a tread cap comprising a tread rubber layer and a tread cap reinforcement, the tread cap reinforcement being covered with steel wires and nylon fibers in the circumferential direction of the tire; two sidewalls extending radially outward from the bead to a crown; two beads intended to come into contact with a mounting rim for fixing the tyre to the rim; and (3) embedding nail holes which are arranged in a full circumference manner, and the rolling circumference per meter does not exceed 50 nail holes.
