To provide a stud-less tire having excellent wear resistance and drive stability, without deteriorating ice brake performance even in a condition wearing in a tread has proceeded.

In this pneumatic tire, a cap tread 6 arranged in the outermost side of a crown part of a carcass 1 is compounded with a granular or short fiber-shaped rough grain of 10 to 300 μm grain size, and is formed by laminating a layer composed of at least two kinds of rubber different in a percentage content of the rough grain. The percentage content of the rough grain is in a range of 2 to 15 vol% of a surface layer 7 arranged in a surface side of the cap tread and 5 to 40 vol.% of an inner layer 8 arranged in a reverse surface of the surface layer, and is 1.3 times of the rough grain percentage content of rubber composition of the surface layer, preferably, ratio of a bulking agent content relating to an extraction component amount by a mixed solvent of acetone and chloroform in an inner layer rubber composition is 1.1 times an outer layer rubber composition.
