Abstract

L'objet de l'invention est de mettre au point un pneumatique de véhicule au moyen duquel les pneumatiques traditionnels peuvent être améliorés. À cet effet, un capteur de pneumatique présentant un guide d'ondes optiques (5) est agencé dans un bloc de la bande de roulement. Le guide d'ondes optiques (5) est réalisé sous la forme d'une ligne de lumière pourvue d'au moins un filtre d'interférence (6, 7, 8, 9) et s'étend sensiblement dans la direction radiale (2) du bloc (4). Lorsque les sculptures du pneumatique de véhicule sont usées, le nombre des filtres d'interférence (6, 7, 8, 9) dans le guide d'ondes optiques (5) est réduit et l'usure des sculptures peut être déterminée par évaluation des signaux lumineux réfléchis dans le guide d'ondes optiques (5).
