Provided is a tire which can improve performance on ice while reducing rolling resistance. This tire is formed by providing a foamed rubber layer on the tread in contact with the road surface, and is characterized in that: the foaming ratio of the foamed rubber layer is 3-50%; the rubber composition configuring the foamed rubber layer contains ethylene-vinyl alcohol copolymer fibers covered by a resin having affinity for the rubber component; and the rubber composition configuring the foamed rubber layer contains, per 100 parts by mass of the rubber component, 5-30 parts by mass of at least one type of inorganic compound powder represented in general formula (I) and having an average particle diameter of 10mum or greater. M・xSiO2・yH2O (I) (In general formula (I), M is a metal oxide or metal hydroxide of a metal selected from the group consisting of Al, Mg, Ti and Ca, and x and y are independently integers 0-10.) |
