    Abstract: A pneumatic tire having an excellent steering stability on wet road surface comprises a tread having an asymmetric directional tread pattern defined by steeply slant grooves and gently slant grooves arranged on at least both side regions, in which so-called directional tread pattern defining a rotating direction (normal rotating direction) of the tire in the mounting of the tire on a vehicle is formed by the steeply slant grooves to contact a side of the groove near to the central region with ground ahead and contact a side apart from the central region with ground afterward. The tread pattern also has gently slant grooves to contact a side of the groove opening to one of tread ends with ground ahead and contact a side of the groove opening to the other tread end with ground afterward.

    Abstract: It is a subject to improve wet performances and noise performances while restricting degradations in dry performances, and for solving this subject, the pneumatic tire is comprised of a tread grounding surface that is partitioned into four to five block regions by three to four main grooves that extend successively in the tire circumferential direction. The main grooves are comprised of one large width main groove which groove width comprises 4 to 20% of a tread grounding width and which is apart from the tire equator by a distance corresponding to 5 to 30% of the tread grounding width further to one grounding end side, and small width main grooves that are disposed between the large width main groove and the other grounding end and which groove width is larger than 2.0 mm but smaller than that of the large width main groove. Both groove side edges of the large width main groove extends in a successive and linear manner in the tire circumferential direction without being interrupted. A ratio ST/SY between a front and rear rigidity ST of the tread grounding surface and a lateral rigidity SY is set to be larger than 0.9 but smaller than 1.1. The lateral rigidity SYs is set to be larger than the front and rear rigidity STs for the shoulder block regions 4s1, 4s2 on both sides. As for the central block region (when the number of main grooves is three, crown block regions 4c1, 4c2, and when the number of main grooves is four, the crown block region 4c2), the lateral rigidity SYc is smaller than the front and rear rigidity STc.

    Abstract: A pneumatic tire includes a tread portion provided with three straight main grooves extending continuously in the tire circumferential direction. The three main grooves are arranged asymmetrically about the tire equator such that an exterior main groove, which is one of the main grooves, is disposed in an exterior half, which is one half of the tread portion on one side of the tire equator. An axially inner main groove and an axially outer main groove, which are the remaining two main grooves, are disposed in an interior half which is the other half of the tread portion. Exterior oblique grooves are disposed axially outside the exterior main groove and inclined at an angle .theta. 1 of 45 to 70 degrees with respect to the circumferential direction of the tire. Interior oblique grooves are disposed axially outside the axially outer main groove and inclined reversely to the exterior oblique grooves at an angle .theta. 3 of 60 to 80 degrees with respect to the circumferential direction. Central oblique grooves are disposed between the exterior main groove and the axially inner main groove and inclined in the same direction as the exterior oblique grooves. Furthermore, between the exterior main groove and the axially inner main groove, the angle .theta. 2 of the central oblique grooves are in the range of 20 to 45 degrees with respect to the circumferential direction.

    Abstract: A large number of sub-grooves inclining in the same direction as a tire rotating direction of a tire circumferential direction towards the outside of a car and extending in a tire width-wise direction are disposed on a tread surface of a tire the tire rotating direction of which is designated in one direction, and at least one main groove extending straight in the tire circumferential direction is disposed in an inside region of the tread surface inner than a tire center line. Further, semi-main grooves crossing the sub-grooves and inclining in an opposite direction to that of the sub-grooves are disposed at a predetermined pitch in the tire circumferential direction in an outside region of the tread surface outer than the tire center line. In this way, a pneumatic radial tire of the present invention has a block type tread pattern having asymmetric directionality.
