A heavy duty low-section pneumatic and a process for manufacturing the same are disclosed. This tire comprises a radial carcass toroidally extending between bead portions, a belt composed of a first and second belt layers successively superimposed around a crown portion of the carcass and a tread rubber having substantially the same width as the maximum width of the belt. In the belt, the first belt layer is composed of at least two cord plies each containing cords inclined at a small angle with respect to the equatorial plane of the tire, the cords of which being crossed with each other with respect to the equatorial plane, while the second belt layer is composed of at least one cord ply containing non-expansible or hardly expansible cords arranged in substantially parallel to the equatorial plane and extends over both sides of the first belt layer between the first belt layer and the carcass. |
