Zusammenfassung:PROBLEM TO BE SOLVED: To enhance uniformity or the like in a pneumatic tire manufactured by a strip winding system. SOLUTION: The pneumatic tire includes a first rubber part 9G formed by spirally winding a first rubber strip 11a around a tire rotary shaft and a second rubber part 4G formed by spirally winding a second rubber strip 11b different from the first rubber strip 11a in composition around the tire rotary shaft and having the contact part which is brought into contact with the first rubber part 9G at least at a part. In the contact part, the end part 21a of the first first rubber strip 11a is abutted to the end 20b of the second rubber strip 11b at least at a part to provide the continuous part (j) of the first rubber strip 11a and the second rubber strip 11b.
