Vehicle wheel pneumatic tyre has tread grooves partly filled by removable mesh structure that indicates wear and increases tyre life

摘要

The tyre has a tread (4) with grooves (5) that are partly filled with a removable mesh structure (6), e.g. covering half their initial depth. The mesh structure has a zone of reduced thickness at one precise point to facilitate cutting for removal, and it is made in a different colour to the tyre for rapid visual indication of its presence or absence.
