The tire has (RG1W/RG2W)/(L2/L1) in a range from 0.6 to 1.12 in a state where the tire is in contact with a road surface. 'L1' is the greatest ground contact length of the center land row in the tire circumferential direction, 'L2' is a ground contact length of the side land row in the tire circumferential direction along a center thereof in the tread width direction, 'RG1W' is a width of the center lug groove, and 'RG2W' is a width of the side lug groove.
