  • Vehicle tire with tractive elements
    Patent number: 4306603
    Abstract: A vehicle tire with tractive elements for positive engagement with the ground surface is disclosed. The tire carcass has a tread including circumferentially spaced raised features. At least one flexible but substantially inextensible belt is positioned radially outwardly of the tread, and a respective plurality of retainer elements are positioned radially inwardly of the belt, the tractive elements being positioned radially outwardly of the belt and being releasably attached to the associated retainer elements for clamping the belt tightly therebetween. Inflation pressure within the carcass expands its crown region to maintain the belt in a taut condition, and at least one element of each set of associated tractive and retainer elements is positively mechanically linked to at least one of the raised features of the tread to limit circumferential displacement of the tractive elements relative to the tread.

  • Pneumatic radial tire with folded ply breaker having soft cushion surrounding breaker edge
    Patent number: 4273177
    Abstract: A pneumatic radial tire has a two-ply tread reinforcing breaker wth cords of filamentary material. The breaker plies are of unequal widths and arranged symmetrically with respect to the median circumferential or equatorial plane of the tire, the overall width of the breaker being substantially the width of the overlying tread. In the region of each shoulder of the tread, the edges of one ply are folded back on themselves forming superimposed two-ply regions and three-ply regions enclosing the edges of a narrow, non-folded ply. Surrounding each two-ply region of the folded ply is a cushion rubber which is softer than the tread or breaker skimcoat rubbers. The breaker construction substantially eliminates breaker edge separation, resulting in a more durable radial tire which can be recapped to provide further service.
