PURPOSE: To obtain satisfactory rim runout resistance and reduce a road noise by disposing a rubber layer having the dynamic elastic modulus at 20°C and the ratio of dynamic elastic modulus at 20°C to dynamic elastic modulus at 60°C specified, respectively, on a bead part made in contact with at least a rim.

CONSTITUTION: A tire has a bead filler 6 disposed in the upper part of a bead wire 5 and a carcass layer 4 disposed around the bead wire 5. In this case, a part close to the surface layer of a bead part 10 contains a bead toe part 11 and has a rubber layer G disposed in the area made in contact with at least a rim R. The dynamic elastic modulus E' (20) at 20°C of the rubber of the rubber layer G is set not less than 6.0MPa. The ratio E' (20)/E' (60) of the above dynamic elastic modulus E' (20) to the dynamic elastic modulus E' (60) at 60°C is set not less than 1.2. Hence, the road noise is reduced without reducing rim runout resistance.
