Provided is a stud tire which has increased holding ability of the stud pins and which has performance on snow and ice and wet performance improved to above the conventional level. This stud tire is characterized in that: stud pins (20) are planted in the tread surface of a tread area (1); the rubber composition forming the tread area (1) is formulated by adding 5-50 parts by weight of carbon black and 5-70 parts by weight of silica to 100 parts by weight of a diene rubber that contains at least one of natural rubber, styrene-butadiene rubber and butadiene rubber; the glass transition temperature of the diene rubber is -60 DEG C or less; the nitrogen adsorption specific surface area of the carbon black is 50-120m2/g; the CTAB specific surface area of the silica is 80-190m2/g; the rubber hardness of the rubber composition is 60 or less; and the product (S*A) of the stress S (MPa) at 400% stretch and the bottom surface area A (mm2) of a flange portion (23) on the bottom of the stud pin (20) is 400-850.
