Abstract: A pneumatic tire for use on trucks, the tire comprising: a tread, the tread having a non-skid depth (NSK), the tread including a first and second shoulder rib and two or more inner ribs, and circumferential grooves interposed between the ribs. The tread pattern is asymmetric, wherein the first shoulder rib has a rib width ratio in the range of about 1.2 to about 1.8, and the second shoulder rib has a rib width ratio in the range of about 1.0-1.6.

Abstract: A unidirectional pneumatic vehicle tire has a symmetric radial carcass and a symmetric package of belt plies placed on the carcass. The tire tread of an asymmetric tread design has at least three longitudinal grooves having a depth of 12 mm to 18 mm. The tire tread has an axially outer wide tread rib, positioned, when mounted on a vehicle, so as to face outwardly relative to the vehicle. The wide tread rib has a width of 25% to 40% of the width of the tire tread when measured at half the depth of an axially outer one of the longitudinal grooves positioned adjacent to the wide tread rib. The wide tread rib is free of any tread voids having a main direction of extension and is selected from the group consisting of longitudinal grooves, longitudinal sipes, transverse grooves, transverse sipes, diagonal grooves, and diagonal sipes. The wide tread rib has tread voids having in a top view of the tire tread a substantially round contour.
