  • Patent number: 8210218
    Abstract: A pneumatic tire which prevents one-sided biased abrasion from being generated, the pneumatic tire having a non-directed rotational direction and comprises lug 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 lug 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 lug 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 lug angle ? 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.
