TIRE

A tread portion 2 includes an outer tread end To, an inner tread end Ti, lateral grooves 3, and circumferential grooves 5. Each region between the lateral grooves 3 and between the outer tread end To and the inner tread end Ti forms a block group 10 in which a plurality of blocks are arranged. The block groups 10 include a first block group 11 and a second block group 12. The first block group 11 has a plurality of first circumferential grooves 6. The second block group 12 has a plurality of second circumferential grooves 7. A connection position of each of the plurality of first circumferential grooves 6 to the lateral groove 3 and a connection position of each of the plurality of second circumferential grooves 7 to the lateral groove 3 are different from each other in a length direction of the lateral groove 3.
