TYRE IMPROVEMENTS

摘要

The present invention relates to a tyre and a method of producing a tyre which includes the step of introducing into a tyre casing (10), a resilient matrix (16) which is then positioned between a tube or a retained supply of air at pressure and the tyre casing. The resilient matrix includes a composite of particles scoured from existing tyres which particles are then bound together by a resilient material and formed into a shape that will together with other shapes of resilient matrix provide the infill. The other shapes or segments are of a shape and size so as to be readily handled for insertion within a casing, and can be of such a size that in a first position they will locate to be positioned between an inner rim of a tyre casing but then be rotated to effectively engage against all of the inner surface of a portion of a tyre casing. The tube (14) itself can be pumped with a material that fills the tube and presses against the segments to effectively lock them into place. Alternatively, with tubeless tyres the material may be pumped into any void within the tyre under pressure until the material sets, if a tube is used the set material may itself be used thereafter as the segments in yet other tyres.
