PURPOSE:To obtain efficient traction performance even on an ungraded land by providing block shaped projections at the intersection parts of a net on the grounding side of the chain main body in a net type tyre chain consisting of elastic bodies of rubber of synthetic resin. CONSTITUTION:A chain unit 2 has a lattice-shaped rubber net unit main body 12 having a reinforcing core material cord and a great number of block shaped rubber projections 13 are provided in one body in the block pattern of the tyre on one side of this rubber net main body 12, that is, at the net intersection points on the grounding side with a tyre fit in position. As the net reinforcing core materials, synthetic fiber cords such as nylon and polyester, etc. or steel cords can be used. With this tyre chain, even an automobile fit with general road tyres can throughly run on any ungraded land such as mud land, etc. |
