Moreover, a middle land portion and a center land portion have a plurality of through lug grooves that pass through the land portions in a tire width direction, respectively. Pitch lengths of the through lug grooves are in a range of from 7% or greater to 14% or less of a tire maximum ground contact length. Additionally, maximum groove depths of the through lug grooves are in a range of from 5% or greater to 65% or less of maximum groove depths of the main grooves.",
