PROBLEM TO BE SOLVED: To provide a studless tire for a truck/bus or a light truck with high performance having sufficient on-ice/on-snow braking force, eccentric wear-resistance and operation stability and making sufficient rolling resistance characteristics and wear-resistance compatible, and to provide the studless tire for a consumer more inexpensively by producing it at a high production efficiency. SOLUTION: In the studless tire for the truck/bus or the light truck, a rubber composition containing a mixture of a zinc salt of an aliphatic carboxylic acid and a zinc salt of an aromatic carboxylic acid, containing 35 mass% or more of a butadiene rubber in 100 mass% of a rubber component and not substantially containing stearic acid is used for a tread.
