(57) [Summary] [PROBLEMS] To improve the braking performance on ice and the rolling resistance without impairing the traveling performance on general roads (dry roads, wet roads), and to further improve the workability of the tread rubber composition at the time of refining and extrusion processing. To provide a pneumatic tire with improved performance. SOLUTION: A pneumatic tire having a tread portion having a multilayer structure, wherein a rubber composition constituting at least one layer of the multilayer structure has a conjugated diene-based rubber having a functional group derived from alkoxysilane in a molecule. A pneumatic tire, which is a composition comprising 100 parts by weight of a rubber component containing 10% by weight or more of coalesced, 10 parts by weight or more of silica, and short fibers having an average length of 10 mm or less. |
