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.
