The subject invention discloses a tire () having at least one sipe pattern comprising, in the circumferential direction of the tire (), one or more straight sipes () and two or more inclined sipes (); wherein at least one straight sipe () is arranged between two or more inclined sipes ().

A stud is inserted into a tread portion of a tire. The first stud includes a tip end protruding from the tread portion for contacting a surface, the tip end comprising a radially outer portion with a first surface, a second surface, a third surface, a fourth surface, a fifth surface, a sixth surface, and a seventh surface, the first surface defining an irregular quadrilateral and extending radially inward from the fourth surface toward a planar side of the tip end; and a base including a flanged bottom portion provided on an end opposite the tip end and extending radially outward, a stump portion provided between the bottom portion and the tip end, and a shank portion interconnecting the stump portion and the bottom portion, the base being embedded and secured in the tread portion of the tire in which the first stud is installed, the bottom portion having a tear-drop shape comprising three planar sides and one semi-cylindrical side.

A stress sensor includes two capacitor plates held in a spaced-apart relationship by a connector block situated therebetween. The connector block includes a plurality of rods protruding from opposite connector block sides and extending into a respective capacitor plate to attach peripheral portions of each capacitor plate to the connector block. A small air gap is maintained between peripheral portions of the capacitor plates by the inclusion of a spacer member. Terminal end portions of the protruding rods are deformed such as by the application of heat over an outer surface of the capacitor plates to retain the capacitor plates in a fixed mutual relationship. The terminal end portions of the rods further serve to prevent horizontal or vertical slippage between the capacitor plates when the sensor is vulcanized into rubber compounds such as in a tire. Once embedded within the rubber compound, the gap between the capacitor plates varies responsively to stress within the rubber compound whereby varying proportionately the capacitance of the device. A signal is directed into the sensor device and an antenna positioned proximate to the device detects the capacitance value between the capacitor plates. As the capacitance varies proportionately with stress within the material, the antenna detects the changes and transmits data to a remote reader that interprets the data to ascertain measured stress within the rubber compound.
