<p>This invention provides a pneumatic tire having a highly improved steering stability, wherein a reinforcing layer formed by spirally winding a strip-shaped triaxial fabric or triaxial fabric-rubber composite having a width W satisfying a relation of the following formula (I): W ‰¥ 2 / 3 × 3 1 / 2 × 2 �¢ b / a + d
[wherein d=4×(D/(ÀÁ)) 1/2 ×10 -2 , D is a thickness (total dtex) of cord constituting the triaxial fabric, Á is a density (g/cm 3 ) of the cord constituting the triaxial fabric, and a is weaving density (cords/b mm) in one axis constituting the three axes] in a circumferential direction of the tire is disposed in one or more of a bead portion 1, a sidewall portion 2 and a belt portion 5.</p> |
