Abstract
It is an object of the present invention to provide a tire that can achieve both wet grip performance and abrasion resistance. Provided is a pneumatic tire comprising a tread part, wherein the tread part is composed of a rubber composition comprising 50 parts by mass or more of silica based on 100 parts by mass of a rubber component, wherein the rubber component comprises 80% by mass or more of a butadiene rubber, and wherein, when ABR represents a content, in % by mass, of the butadiene rubber in the rubber component and L represents a land ratio, in %, of a tread surface of the tread part, ABR and L satisfy the following inequality: A BR × L > 4800.
