    摘要： An anti-skid stud for insertion into the tread of a vehicle tire is disclosed. The stud comprises a support body part extending in an axial direction and a pin body part, the support body part comprising a bottom portion, a middle portion, and a head portion having an upper surface, wherein the pin body part extends beyond the upper surface of the head portion, and wherein, when viewed in top view onto the head portion, (i) the location of the center of gravity of the head portion is laterally offset from the center of gravity of the bottom portion; or (ii) the location of the center of gravity of the pin body part is laterally offset from the center of gravity of the bottom portion; or (iii) the location of the center of gravity of the pin body part is laterally offset from the center of gravity of the head portion; or (iv) the location of the center of gravity of the middle portion is laterally offset from the center of gravity of the bottom portion. Also, a pneumatic tire comprising a tread, the tread comprising a plurality of such anti-skid studs is disclosed. The majority of the studs may be oriented in a common direction.

    摘要： A pneumatic tire comprising a carcass and a tread located radially outward of the carcass and extending between the tire sidewalls is disclosed. The tread provides a tread running surface and comprises a first, radially outer tread layer comprising a first rubber compound and a second, radially inner tread layer comprising a second rubber compound, wherein the second tread layer is located radially adjacent to the first tread layer, and wherein the first rubber compound is different from the second rubber compound. The second tread layer comprises a plurality of integrally formed extensions of the second tread layer extending from the second tread layer radially outwardly to the tread running surface. The first rubber compound and the second rubber compound each comprise at least at least 30 parts per hundred parts of rubber (phr) of silica. Each of the extensions has a width as measured in the axial direction of the tire in a range of from 1 to 15 mm.
