ABSTRACT:
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 60 kgf/cm2or 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.
