    Abstract: A pneumatic tire particularly adapted for use over water wet surfaces having a tread portion provided with water-absorbing chambers of relatively small cross-sectional area at the groundcontacting surface of the tread, such as cylinders of small diameter, extending radially inwardly into the tread, for absorbing water during contact of the chamber with the water wet surface, and ejection of absorbed water at a later stage in a revolution of the tire.

    Abstract: A pneumatic tire provided with a plurality of generally axially outwardly extending faces on at least one of its shoulder portions. The faces may engage with water standing on the surface over which the tire is to run and/or may be engaged with water thrown up from the surface. This engagement imparts a rotational effect to the tire in the manner of a turbine, which tends to reduce the slipping of the tire on the surface. The engagement also tends to reduce the trajectory (angle and distance) of the water thrown up from the surface by the tire.
