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 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 circumferential rib region 4c2), the lateral rigidity SYc is smaller than the front and rear rigidity STe.

Abstract: A groove bottom of a circumferential groove formed in a tread surface is provided with a protruding stripe extending along a next ending direction of the circumferential groove. The protruding stripe is provided with a top head portion protruding toward a tire outer circumferential side, and a base portion which is narrower than the top head portion and connects the top head portion and the groove bottom. If a small stone is pinched, the top head portion is inclined around the base portion, and the protruding stripe is deflected as a whole, thereby generating a reaction force on the basis of a deformation restoring force.

Abstract: The present invention provides a truck tire with a siping geometry to protect the main ribs of the tire's tread by delaying the onset of irregular wear and the growth thereof. The improved tire tread comprises a plurality of main ribs formed by grooves extending generally circumferentially around an outer surface of the tire forming a tread width for contacting the supporting surface. A plurality of sipes, positioned on both lateral edges of each one of the main ribs, provide protection for the main ribs to delay the onset of irregular wear. A pitch length and a sipe length are both selected to be within a certain range of values, as well as a ratio of the sipe length to the pitch length is selected. The sipes are preferably narrow in width having a maximum width dimension of about 0.40 millimeter. The sipes may be inset from the lateral edges of the ribs, may be curvilinear sipes, may have an inclination angle with respect to a normal to the ribs and may be at an acute angle from the circumferential direction of the tire tread.
