The invention provides a series combined tyre antiskid pedrail. The structure of the series combined tyre antiskid pedrail is composed of girdles, girdle buckles, antiskid bands, antiskid fasteners and tightening ropes. The middle of a girdle is provided with row-holes. Two ends of the girdle are provided with the girdle buckles. The tightening rope passes through the girdle buckles to connect the girdles in series to form an antiskid pedrail. The middle of the antiskid band and the girdle is provided with same row-holes. The antiskid fasteners penetrate the row-holes to fix the antiskid band to the middle of the girdle. The upper end of the tightening rope is fixed with the girdle buckle at the upper end of the antiskid pedrail. The lower end of the tightening rope is provided with a hook which passes through the upper end of the antiskid pedrail to be fixed in the same girdle buckle at the upper end of the tightening rope. The lower end and the upper end of the antiskid pedrail are connected to form a ring to be wound around the excircle of the tyre. Meanwhile, the tightening ropes at two sides of the antiskid pedrail are pulled to coat two sides of the tyre with two sides of the antiskid pedrail.
