Provided is a tire comprising a tread part of a rubber composition comprising a rubber component comprising an isoprene-based rubber and a styrene-butadiene rubber, wherein a vinyl content of the styrene-butadiene rubber is greater than 26 mol%, wherein a given ratio A of an ash content of the rubber composition is greater than 25 mol%, wherein the tread part comprises two or more circumferential main grooves extending in a tire circumferential direction, and land parts partitioned by the circumferential main grooves, wherein at least one land part of the land parts comprises at least one given flask-like circumferential groove extending in the tire circumferential direction.",
