Abstract:
1. A heavy-goods vehicle tire comprising: two beads adapted to be mounted on a wheel rim and disposed on respective first and second sides of the tire; a crown provided with a tread having a running surface adapted to contact the ground; first and second sidewalls for joining the respective beads to the tread; first and second protuberances projecting from respective first and second sidewalls for laterally deflecting water expulsions when running on a wet road, wherein the first protuberance is located radially between the second protuberances and the unworn running surface; each of the first and second protuberances being located entirely radially outwardly of an axially outermost point of the respective sidewall, and containing the outermost axial point of the tire relative to the side of the tire on which the protuberance is located; each of the first and second protuberances on the tire when new being radially offset relative to the running surface, a length of each radial offset being measurable in a meridian section plane of the tire and defined as a distance perpendicular to the tire's axis from an axially outermost first point of the tread on same tire side as the respective protuberance, to a second point where a line extending from such axially outermost point is tangent to an axially outer end of such protuberance's profile, said line making no contact with any portion of the tire disposed between the first and second points; wherein the respective lengths of the radial offsets are different from one another, the difference between the lengths of the radial offsets being less than the thickness of the tread; and wherein, in an unworn state, a virtual straight line between the axial end point of the running surface and a point of tangency of the first protuberance forms an angle α
