CA 2373023

In a sealant-containing tire, an outer liner is fastened to an inner surface of a tread of a tire body, and a sealant chamber that is filled with sealant is defined between the outer liner and the inner liner, with an air chamber filled with air also being defined within the inner liner. By making the inner liner of flexible rubber of a 300% modulus of 60kgf/cm2 or less, not only is a puncture in the inner liner caused by a nail made smaller, but the puncture is rapidly made smaller after withdrawal of the nail so that the flowing out of air from the air chamber is delayed. The flexible inner liner can easily be deformed by the air pressure within the air chamber and the sealant within the sealant chamber is therefore rapidly pushed into a puncture of the tread by the air pressure, thereby effectively repairing the puncture.

L'invention concerne un pneumatique renfermant un agent d'étanchéité, dans lequel un garnissage externe adhère à la surface interne d'une bande de roulement, une chambre d'agent d'étanchéité remplie d'agent d'étanchéité est formée entre le garnissage externe et un garnissage interne, et une chambre à air remplie d'air est formée à l'intérieur du garnissage interne. Le garnissage interne est en caoutchouc mou de 60 kgf/cm<2> ou moins en module de 300 %, non seulement pour réduire les dégâts de crevaison occasionnés au garnissage interne par des clous mais encore pour limiter l'extension des dégâts après l'extraction des clous, ce qui permet de retarder les fuites d'air hors de la chambre à air. En outre, sachant que le garnissage interne mou peut être déformé facilement par la pression d'air dans la chambre à air, l'agent d'étanchéité de la chambre d'étanchéité est expulsé du même coup immédiatement vers la zone des dégâts sur la bande de roulement selon une pression d'air qui permet une réparation effective.
