A system for mounting a housing and an insert to a tire includes a housing configured to be installed in a tire, wherein the housing has a top opening. The system also includes at least one anchor connected to a side of the housing in an un-deployed configuration. The system further includes an insert configured to be inserted into the top opening of the housing. The at least one anchor projects outward into the tire when the insert is inserted into the top opening of the housing.

Tyre for a wheel of a vehicle, with a profiled tread for supporting the vehicle on the ground, provided with an adjustment device for adjusting a tread pattern height of the profiled tread. Method for at least partly replacing a profiled tread of such a tyre.

A ground contact region of the tread portion of a studdable tire includes a center region located over a range corresponding to a length of 5 to 25% of a ground contact width from a tire centerline on each of both sides of the tire centerline in a tire width direction; and two shoulder regions located on both sides of the center region in the tire width direction. In each of the center region and the shoulder regions, a plurality of the stud pin installation holes are disposed along each of four or more pin arrangement lines extending in a tire circumferential direction. An average value of adjacent intervals between the pin arrangement lines in the center region is larger than an average value of adjacent intervals between the pin arrangement lines in each of the shoulder regions.

In a stud pin, a flange contour shape of a lower flange is an anisotropic shape in which, among imaginary rectangles circumscribing the contour shape, the smallest rectangle includes short sides and long sides having different lengths. The flange contour shape includes first recess portions on each of portions of the flange contour shape extending along the short sides, the first recess portions being curved toward a centroid of the flange contour shape, and the flange contour shape includes a second recess portion on portions of the flange contour shape extending along the long sides, the second recess portions being curved toward the centroid of the flange contour shape. A body contour shape of a body portion is a polygonal shape including vertex angles in a same number as the first and second recess portions, and the vertex angles are disposed facing the first and second recess portions.
