PROBLEM TO BE SOLVED: To provide a lightweight and high-strength tire. SOLUTION: This tire 1 is constructed by using a rubber composition containing carbon black, silica and an organosilane compound; wherein the rubber composition also contains at least inorganic hollow particles <=1μm in average size. Incorporation of the hollow particles provides the tire with lightweightness, and by designing the average size of the hollow particles to be <=1μm, the hollow particles can be prevented from breakage and the lightweightness of the tire can be secured; furthermore, by composing the hollow particles of highly hard inorganic matter, the rigidity of the tire 1 can be raised, improving both the abrasion resistance and puncture resistance thereof.
