摘要： In a pneumatic low section tire with an aspect ratio (height/width) of 0.65 or less, when a green tire is pressurized with a bladder within a mold, tread rubber is forced to flow into recesses for forming a tread block pattern. With this rubber flow, the belt is subjected to deformation toward the same recesses, so that the belt layer deforms outward at the middle of the transversal grooves between two main circumferential grooves. This deformation causes the skid base rubber existing between the transversal groove bottom and the belt layer to be thin at the middle of the transversal grooves, thus resulting in an early trouble. To overcome this problem, the transversal grooves are formed in raised bottom or corrugation fashion along a longitudinal direction thereof, to obtain a uniformly thick skid base. Further, this raised bottom serves to increase the drainage effect during rainy weather running.

摘要： A high performance pneumatic radial tire comprises a toroidal carcass, a tread radially outside a crown portion of the carcass, a belt layer interposed between the carcass and the tread and having a same width of the tread, and an auxiliary layer arranged between the belt layer and the tread and covering the entire belt layer. organic cords are buried substantially parallel to an equatorial plane of the tire in the auxiliary layer, and land portions are defined between at least two circumferential main grooves formed in an outer surface portion of the tread and between the circumferential main grooves and axially opposite edges of the tread. In the tire, a rigidity of the tire corresponding to locations overlapping the circumferential main grooves is made smaller than that of portions corresponding to the land portions by, for example, constituting the auxiliary layer from at least two auxiliary plies comprising one auxiliary ply located on a radially innermost side and covering the belt layer over an entire width thereof, and cutting at least a radially outermost auxiliary ply at locations overlapping the circumferential main grooves among the auxiliary plies having portions overlapping the circumferential main groove.

摘要： To prevent tire unbalanced abrasion, that is, tire unbalanced rigidity between the acute angle corners and the obtuse angle corners of blocks forming a tire tread pattern, without decreasing the tire drainage and increasing tire pattern noise, block side walls extending along the main circumferential grooves are sloped down to the bottom of the main grooves in such a way that an inclination angle between the tread surface normal line and the block side wall increases gradually from the obtuse angle corners of the blocks to the acute angle corners thereof. Preferably, the inclination angle is 8 degrees at the obtuse angle corner and 25 degrees at the acute angle corner on the wide main circumferential groove, and 7 degrees at the obtuse angle corner and 13 degrees at the acute angle corner on the main circumferential grooves adjacent to the wide main groove.

摘要： A pneumatic radial tire comprises a tread provided with a plurality of circumferential grooves extending in a circumferential direction of the tire, and plural rows of land portions defined between axially adjacent circumferential grooves and between each of edges of the tread and the adjacent main circumferential groove. That groove wall of at least the circumferential groove located nearest to at least one of the tread edges on a treading surface of the tread which is positioned on a side of the one of the tread edges is inclined to gradually increase a width of the groove toward the surface of the tread from a location spaced by 10-70% of a depth of the circumferential groove radially outwardly from a bottom thereof. The width of an opening of the circumferential groove to the surface of the tread is in a range of 3-18 mm.
