The invention aims to provide a pneumatic tire achieving a balanced improvement in dry grip performance and abrasion resistance. The invention relates to a pneumatic tire including a component that contacts a road during running, the component being formed from a rubber composition for a component that contacts a road during running which contains: SBR; a short cellulose fiber having an average fiber length of 10 µm to 10 mm; and a silica having a N 2 SA of 100 m 2 /g or more and/or a carbon black having a N 2 SA of 70 m 2 /g or more, the SBR being present in an amount of 60% by mass or more per 100% by mass of the rubber component, the rubber composition containing, per 100 parts by mass of the rubber component, 0.1-20 parts by mass of the fiber and at least 60 parts by mass in total of the silica and/or the carbon black.
