摘要： Disclosed is a pneumatic tire for a construction vehicle, which enhances a reinforcement effect by protectors provided on a sidewall portion. This pneumatic tire includes: at least two convex-shaped protectors extended in a tire circumferential direction, the protectors being provided in a range of 30 through 65% of a tire cross-sectional height on at least one of sidewall portions; and elastomeric reinforcing members buried inside the protectors, wherein a 100% modulus of the elastomeric reinforcing members is set at 5 through 25 times a 100% modulus of a rubber composition of the sidewall portion adjacent thereto.
