摘要： The invention relates to a moulding element for a mould for a tyre comprising a tread provided with a plurality of blocks. Each block comprises a contact surface intended to come into contact with a road surface during running. The moulding element also comprises a moulding surface for moulding the contact surfaces of the blocks. The moulding surface comprises a plurality of ribs intended to mould fine grooves in the blocks. These ribs have a height of between 0.005 and 1 mm, a width of between 0.01 mm and 0.3 mm and the pitch (P) of the ribs is between 0.1 and 2 mm. The moulding surface comprises at least one rib-free measurement zone able to accept measurement means. This measurement zone has the overall shape of a disc the diameter of which is greater than 3 mm.

摘要： A pneumatic tire for ice-bound or snow-covered roads, which has fine grooves formed in the tread surface, thereby improving the brake performance on ice-bound roads in early periods of wear. This pneumatic tire for ice-bound or snow-covered roads has its tread partitioned into a plurality of lands, these lands being formed with sipes, wherein the tread surface at the lands is formed with a plurality of fine grooves shallower than the sipes, the edges of these fine grooves being curved. Further, the width of the openings in the fine grooves is larger than the width of the bottoms. Further, the angle of the fine grooves with the peripheral direction of the tire is 42 - 60°.
