Abstract: The present invention provides structures on the tread of a tire that improve the evacuation of mud, soil and the like. In particular, different tread features are provided that may improve the evacuation of mud, soil and the like by themselves or by strategically combining them. These different tread features may be tested to see how they affect mud evacuation at different rotational speeds by a test apparatus that mimics the performance of a tire. For example, a tread that has offset shoulder tread blocks, which shows good mud evacuation at lower speeds, may be combined with shoulder grooves with pockets that show good mud evacuation at intermediate speeds to see if this combination provides a solution that has the lowest change of speed necessary to evacuate 50-87% of the mud found in the grooves.

Abstract: An object of the present invention is to provide a pneumatic tire which prevents one-sided biased abrasion from being generated. A pneumatic tire according to the present invention has a non-directed rotational direction and comprises rug grooves 20 cutting across a land portion at a shoulder side of a tread portion 16 at both sides in a tire width direction. Each of the rug grooves 20 has a tapered groove portion 21 such that the groove width gradually becomes narrower such that a trapezoidal block portion 22 having a short side at the shoulder side as seen from a tire tread surface side is formed between the rug grooves 20 in a tire peripheral direction. The tapered groove portion 21 is formed so as to extend beyond a one quarter point Q from a tread end T. Accordingly, since in whichever direction the pneumatic tire 10 is rotated, a rug angle α of a trailing end near the one quarter point Q becomes 90 degrees or less, it is possible to prevent one-sided biased abrasion from being generated.
