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.
