Abstract
A heavy-duty tire includes a tread portion including a crown land portion, a shoulder land portion with a tread edge and a middle land portion disposed therebetween. In a tire cross-section of a 5% inflated state, the tread portion comprises a surface profile which comprises an inner arc portion having a radius (R) of curvature with a center located in a tire equatorial plane and an outer arc portion having a radius (R) of curvature smaller than the radius (R) of curvature of the inner arc portion and intersecting the inner arc portion at an inflection point (P). The inflection point (P) is located on the middle land portion, wherein a distance (Lp) in the tire axial direction from the tire equatorial plane to the inflection point (P) is in a range of from 0.35 to 0.50 times a tread half-width (Wt).
