A strip located between a rim and an inner tube of a tire includes a non-flexibility fabric portion and a flexible section which is connected between two ends of the fabric portion so as to become a loop to wrap around the rim. The fabric portion is much longer than the flexible section and an aperture for the inflation valve is defined through the fabric portion. The fabric portion is durable and having a better structural strength so as to provide a better protection for the inner tube.
