A pneumatic tire has a block pattern which is divided by a center main groove extending straight on the tire equator, two outer main grooves extending straight outside the center main groove, inner lateral grooves crossing between the center and outer main grooves, and outer lateral grooves crossing between the outer main grooves and tread edges so as to make two inner block rows and two outer block rows. The outer lateral grooves cross the outer main grooves, and the inner lateral grooves cross the center main groove at an inclination opposite to an inclination direction of the outer lateral grooves.
