Zusammenfassung:	Provided is a tire that can have improved snowy road performance while maintaining steering stability on a dry road surface. The tire is a tire 1 in which a first crown axial groove 7 is provided in a first crown land portion 5A so as to traverse an overall width of the first crown land portion 5A and a second crown lug groove 8 is provided in a second crown land portion 5B so as to extend from a crown main groove 3 and terminate within the second crown land portion 5B. An opening 7a of the first crown axial groove 7 at the crown main groove 3 is located so as to at least partially overlap an opening 8a of the second crown lug groove 8 at the crown main groove 3 in a tire circumferential direction. An intersection angle ± formed by a longitudinal direction of the first crown axial groove 7 and a longitudinal direction of the second crown lug groove 8 is 120 to 150 degrees.
