PROBLEM TO BE SOLVED: To provide a pneumatic tire for a heavy load vehicle suitable for a vehicle of a magnetic levitation type and capable of restraining early stage abrasion of a tread rubber without generating adhesion-peeling-off trouble and rubber breakage trouble between the tread rubber and a belt. SOLUTION: A rubber provided by vulcanizing a rubber composition containing 40-55 wt.pt. of carbon black, and 2.5-4.0 wt.pt. of mixture comprising sulfur and an organic thiosulfate compound expressed by the formula MO3S- S-(CH2)n-S-SO3M, per 100 wt.pt. of a diene-based rubber, preferably containing butadiene rubber with 95% or more of cis-isomer content, is arranged in a portion contacting with a road face of a tread part in a pneumatic tire. In the formula, (n) represents 3-10, and M represents one equivalent of lithium, potassium, sodium and the like.
