PURPOSE: A vehicle tire with an improved tread is provided to secure enough thickness from a belt layer to an exterior profile by considering the thickness of a tread outside a deck line. CONSTITUTION: A vehicle tire comprises an exterior profile(6) considering the thickness of a tread(1) outside a deck line(5). In the exterior profile, the ratio of A, B, and C is 1:0.89~0.93:0.79~0.83, where A is the depth of a second groove from the deck line, B is the thickness from the deck line to the tread surface at the point apart by 75% of half the tread width from the center of the tread, and C is the thickness from the deck line to the tread surface at the point apart by 10mm from the B point.
