    摘要： A pneumatic tire comprising a tire tread wherein a foamed rubber layer is provided at least in the portion substantially contacting with a road surface, and wherein said foamed rubber layer, which has closed cells, has an expansion ratio of about 2% to about 50%, and the solid rubber phase in said foamed rubber layer contains, in an amount of about 0.5 to about 5 parts by weight per 100 parts by weight of the rubber component, a vulcanization accelerator represented by one of the following general formula: ##STR1## wherein R.sup.1 and R.sup.2 each independently represents an atom or a group selected from a group consisting of a hydrogen atom, alkyl groups, and aryl groups, excluding a case in which each of R.sup.1 and R.sup.2 simultaneously represents a hydrogen atom. The pneumatic tire which is used as an excellent studless tire suppresses deterioration in performance on ice or snow in the final period of tire use compared to the performance in the initial period of tire use.
