Abstract

PURPOSE: To prevent a tire from being punctured by a protrusive object on the road for the pneumatic tire internally contained with a tube, by interposing a tube protector between a tire main body and the tube internally circumferentially of a crown part of the tire main body.
CONSTITUTION: In a tire with a tube, an annular tube protector 8, substantially independent of a tire main body 3, is intermediately arranged between a tube 7 and the tire to the inner circumference of a crown part 4 of the tire main body 3. This protector 8 is formed a rubber-state elastic material dispersed with material having both penetration resistance, blocking penetration of a protrusive object 2 against puncturing force in the point end of the protrusive object 2 punctured to the crown part 4 under the support by pressure of filled air in the tube 7, and locally hollowing flexibility with the tube 7 under the charged pressure, that is, a fine fabric or knitted goods constructional material consisting of various fibers, or reinforcement material composed of various short fiber and/or long fiber.
