System for testing pneumatic tires. A tire that revolves under a load is deformed at the area in which it meets the roadway. Such a deformation results in the tire having an effective rolling radius that is shorter than the radius it has while static and/or unloaded. According to the invention, tires are tested by determining their effective rolling radii. When tires having similar effective rolling radii are used on an automotive vehicle, the undesirable torque steer effect is thereby reduced.

System for testing a tire to avoid a torque steer effect

A method and an apparatus employing a formed guide shoe assembly controls the placement of successive convolutions of elastomer-coated wire on a bead-winding drum. The guide shoe assembly is not rotatable but accommodates the softly coated wire slidably along an extended curvilinear groove to initial contact with the winding drum or with preceding convolutions of coated wire thereon. A convergent channel in the assembly ensures safe smooth approach to the curvilinear groove. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Making bead rings for vehicle tires

In apparatus for grinding arc portions of parts of the width of a tire tread, apparatus for controlling tilt of the grinding wheels relative to the tire rotation plane makes use of three paddles having arc contours for lengthened contact with the circumference of the tire tread and means for adjusting the location of the contour relative to the tire and grinding wheel centers to accommodate differences in diameter of one tire from another. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
