Title (EN) TIRE HAVING MULTILEVEL SONIC WEAR INDICATORS
(FR) PNEUMATIQUE MUNIS DE TEMOINS D'USURE SONORES MULTINIVEAUX
Abstract:
(EN) The invention relates to a tire (10) including two sets (E1E2) of sonic wear indicators (TUS1-TUS2) corresponding to two wear thresholds so as to generate noise when each threshold is exceeded. Each indicator (TUS1-TUS2) of each set (E1E2) is axially aligned with each of the other indicators (TUS1TUS2) of the set (E1E2). The number of set(s) (E1E2) of indicator(s) associated with each threshold is different from the number of set(s) of indicator(s) associated with each of the other thresholds. The sets (E1E2) of threshold(s) (TUS1TUS2) associated with each threshold are equidistantly circumferentially distributed over the tire (10). Each indicator is made of a rubber projection extending from the bottom of a circumferential groove.
(FR) Le pneumatique (10) comprend deux ensembles (E1E2) de témoin(s) d'usure sonore (TUS1-TUS2) associé à deux seuils d'usure de façon à générer un bruit au-delà de chaque seuil. Chaque témoin (TUS1-TUS2) de chaque ensemble (E1E2) est aligné axialement avec chaque autre témoin (TUS1TUS2) de l'ensemble (E1E2). Le nombre d'ensemble(s) (E1E2)de témoin(s) associé(s) à chaque seuil est différent du nombre d'ensemble(s) de témoins(s) associé(s) à chaque autre seuil. Les ensembles (E1E2) de témoin(s) (TUS1TUS2) associé(s) à chaque seuil sont équi-répartis circonférentiellement sur le pneumatique (10). Chaque témoin est formé par une saillie de gomme, s'étendant à partir du fond d'un sillon circonférentiel.
