Abstract: A measurement system scans the given surface of a tire component (e.g., a brush-finished tread or buffed tire casing) to electronically measure data points corresponding to vertical and horizontal coordinates along the given surface. Associated computer processors electronically calculate the slope at a plurality of different locations by determining the degree of steepness (e.g., rise over run, angle or grade) between selected ones of the first and second coordinates and electronically comparing at least one slope-based parameter to one or more predetermined levels to determine a characterization defining one or more of surface adhesion fitness, finishing brush wear level and brush bristle placement location. Slope may be determined between every adjacent pair of data points or between selected data points (e.g., identified local maximum and minimum). The at least one-slope based parameter compared to the predetermined levels may correspond to the slopes themselves or to a calculated average slope value.

Abstract: A safety wheel has on the surface thereof a tread design comprised of a relatively hard material which defines interstitial spaces, which spaces are filled with a relatively soft material. The overall surface of the resulting safety wheel is substantially smooth, while the softer material filling the interstitial spaces absorbs unevenness in a surface traversed by the wheel. In embodiments where the interstitial spaces are generally circular in nature, a suction force is created by interaction between the surface traversed, the soft material filling the interstitial spaces, and the hard material immediately defining the interstitial spaces. This suction force provides greater traction for the wheel on the traversed surface, thereby enhancing the safety of the wheel. Other non-circular interstitial space shapes are disclosed. The broader features of this invention (i.e.

Abstract: An anti-skid stud which comprises a plug or matrix in which are embedded one or more wire-like strands of great wear resistance material such as iron, steel, siliceous material, plastics, etc., which protrude from the matrix. The stud is installed in the surface of tires with the wire-like strands protruding to the road surface. These protrusions penetrate ice and snow surfaces to provide anti-skid traction, however on surfaces such as bare concrete these protrusions flex and do not penetrate the surface to cause excessive erosion of the concrete surface.
