Abstract: A winter tyre is equipped with studs. The number of studs in the tyre is greater than that stated in the amendment, dating 1 Jun. 2009, to the Finnish Ministry of Transport and Communications Decree 408/2003 concerning vehicle tyre studs. The shape of the stud together with the elasticity of the winter tyre rubber compound creates a piercing force of less than 120 N on the stud. The invention also relates to the stud for a tyre, the tip of the stud being resistant to wear and having a cross-section of 1.80-3.14 mm2.

Abstract: In a stud embedded in a tire to provide the braking force, a set of a plurality of long stud elements are arranged adjacent to one another and bundled into a predetermined shape with one end faces thereof faced to a road. Each of the stud elements is formed by a synthetic fiber or a synthetic resin wire. The stud further has a filler filled in a space between adjacent ones of the stud elements to fasten the stud elements to one another. The stud is deflected during running to distribute the stress so that the desired braking force is assured and the durability is improved.
