<p>A pneumatic tire having a part formed by laminating of ribbonlike rubber that inhibits the progression of cracking from the surface of laminated part of ribbonlike rubber, such as side wall, enhancing the durability of the pneumatic tire. The external surface of laminated part (40), such as side wall (31), of pneumatic tire formed by winding/laminating of ribbonlike rubber (50) is provided with surface layer (41) formed by bonding a rubber sheet so that any unevenness and adherence failure of the laminated part (40) are covered thereby so as to attain smoothening of the tire surface. Thus, the progression of cracking from tire surface due to tensile force (P) and compressive force (Q) at flexure is inhibited.</p> |
