Additionally, the groove width Wg2 of the center main groove 22 has a relationship Wg2 < Wg1 with the groove width Wg1 of the shoulder main groove 21. A distance Wce between outer side edge portions in a tire width direction of the pair of center land portions (32, 32) has a relationship 0.50 ≤ Wce/TW with a tread width TW. Additionally, a width Wr2 of the center land portion (32) has a relationship 0.23 ≤ Wr2/TW ≤ 0.27 with the tread width TW. Additionally, the center land portion (32) includes circumferential narrow grooves (321) that extend in the tire circumferential direction.",
