Abstract: A method for installing a stud in a tyre. The method includes identifying a stud hole for the stud in the tyre; imaging the vicinity of at least the stud hole, whereby information is received about the pattern in the vicinity of the stud hole, and using the received information to determine [i] the stud type suitable for the stud suitable in the stud hole and/or [ii] the suitable stud orientation of the stud suitable in the stud hole. The method includes providing a stud and installing it in a stud hole. The stud type of the stud is the same as the suitable stud type of a stud suitable in the stud hole; and/or the stud is installed in the stud hole in such a way that the main direction of the stud is parallel with the suitable stud orientation. Further a tyre studded by the method.

Abstract: A pneumatic tire includes stud pins inserted into holes disposed in the tire surface. The stud pins each include a body portion and a flange disposed closer to the bottom side of each of the holes than the body portion and having an outer diameter larger than the body portion. The holes each include a securing portion coming into contact with the outer peripheral surface of the body portion of the stud pin to secure the stud pin and an enlarged diameter portion disposed closer to the bottom wall side of the hole than the securing portion, having an inner diameter larger than the securing portion, and coming into contact with the outer peripheral surface of the flange of the stud pin to secure the stud pin. The side wall of the enlarged diameter portion is provided with a protrusion protruding toward the interior of the hole.

Abstract: Segmented tires employ segments featuring cooperating recesses and protrusions at opposing sides thereof for mating of the segments with one another in the assembled tire body. Cleated tires with embedded cleats of greater rigidity than the tire body material provide improved traction in muddy or other slippery conditions while the compressible tire body smooths out the ride harshness of the tire. Mounting elements are also embedded within the segments of the tire body for secure mounting and reliable retention of the segments.

Abstract: A steel-cleated, all terrain tire has cleats that dynamically engage with changing road conditions, across slick ice and bridges, and while turning, breaking and accelerating on steep terrain. The tire design can provide stability and an enormous safety benefit in dangerous conditions, on demand, without the driver's intervention. The tire design can be used for military vehicles and aircraft, commercial jets, turboprop aircraft, heavy equipment, commercial diesel trucks, helicopters, law enforcement vehicles, fire and rescue vehicles, school buses, government vehicles, sport cars, and the like. The tire design include spring loaded cleats that can are spaced about and extend outward from the tire's surface. The spring load may be strong enough to permit the cleat to penetrate ice and the like, while not damaging asphalt or concrete roadways.
