A tyre wear indication system comprising reinforced tubes 1a that are provided in the tyre tread and a cavity 1c. The cavity is filled with a material of a different density to the tyre. The tube and cavity are positioned in the tyre so that when the tyre wears to a critical wear level, the end of the tube is worn down such that the material contained in the cavity is released it causes vibrations which alerts the driver to the tyre wear. The cavity may additionally comprise a pad 1d that comprises a variety of materials that cause a weight imbalance once the tubes or cavity have worn and release the material stored inside. The material may also be coloured so that when the tube is worn by road surface a visual indicator is provided around the tyre and complements the vibrations felt by the driver as a indication means. The system may also be retro fitted by a professional to a tyre without this system.
