Abstract: A method and apparatus for storing a plurality of tires having a threaded portion, a rim portion and two sidewall portions, said method comprising the following steps; peripherally slicing each of said tires in two half tires along said threaded portion about midway between said sidewall portions; performing radial incisions in each of said two half tires, said incisions extending through said threaded portion and part of said sidewall portion; stacking up said half tires one on top of the other in order to form a pile of half tires; compressing said pile longitudinally in order to flatten said half tires one over the other; whereby, said radial incisions allow the threaded portion of each half tire to lie in the same plane as the sidewalls of the same half tire without warping when said half tire is compressed into a flattened condition.

Abstract: The novel signalling post is adapted to be mounted on a flexible base member. The post comprises an outer, hollow, substantially rigid, transparent polycarbonate tubular member. The polycarbonate tubular member has a memory for returning to its original shape upon impact. An inner opaque flexible plastic tubular member is mounted inside the transparent tubular member and has a diameter to fittingly slide inside the transparent tubular member. The opaque tubular member has substantially no memory. The polycarbonate tubular member has a memory which allows the flexible opaque tubular member to maintain a substantially rigid shape and to return to its original shape if slightly deformed upon excessive impact. The transparency of the outer tubular member allows the introduction of a colored or reflecting film between both tubular members for simultaneously displaying a visual signal through the transparent tubular member while the latter protects the film against damages.
