摘要: A pneumatic tire has paired bead portions, paired sidewall portions, a tread portion, a plurality of lug grooves extending from a shoulder area of the tread portion to reach a buttress area of the sidewall portion, and a block defined by the plurality of lug grooves. The block includes a shoulder block provided in the shoulder area and a buttress block provided in the buttress area. At least some of the plurality of lug grooves end at a connecting portion connecting the paired buttress blocks, the connecting portion is provided on an inner side in the tire diametrical direction of position that are 50% of length in the tire diametrical direction of the buttress block from upper end position of the buttress block. A step or a protrusion where the buttress block has a largest upraised height is provided in the tire diametrical position of the connecting portion.

摘要: A tire for running on rough terrain comprises a tread portion 2 bound with an intended tire rotational direction. The tread portion 2 comprises a row of crown blocks 10 and rows of middle blocks 11. The crown blocks 10 and the middle blocks 11 each has an axially-elongated shape. A crown front edge 15 of each of the crown block 10 comprises a most concave portion 18 positioned at the most toe-side thereof in the tire rotational direction and a pair of inclined edges 20 extending from the most concave portion 18 toward axially both sides thereof and toward the heel-side in the tire rotational direction. The inclined edges 20 are each inclined at an angle from 10 to 45 degrees with respect to the tire axial direction. A middle front edge 21 of each of the middle blocks 11 extends axially outwardly and is inclined to the heel-side.

摘要: A pneumatic tire has a pair of bead portions, side wall portions and a tread portion. An annular projections group in which plural kinds of projections having different volumes are arranged in a tire circumferential direction, is formed on an outer surface of a buttress region of the side vail portion. On the assumption that a virtual line is defined by connecting a maximum height position at the center in a width direction of a projection included in the annular projections group, and a maximum height position at the center in the width direction of another projection which is adjacent to the projection, an angle of inclination θ formed by the virtual line and an outer-surface in the buttress region of the side wall portion in a tire diametrical direction view goes beyond 3 degrees and is equal to or less than 13 degrees.

摘要: A rubber component for a tire is disclosed that is manufactured from a rubber composition that is based upon a cross-linkable elastomer composition that includes 100 phr of two elastomer types including at least 50 phr of a styrene-butadiene copolymer (SBR) with a polybutadiene (BR) as the remainder. Such compositions may further include between 75 phr and 130 phr of a carbon black. Also included in such elastomers is a plasticizing system that includes a plasticizing resin having a glass transition temperature (Tg) of at least 25° C. and a plasticizing liquid. The plasticizing system is added in an effective amount to provide the cured rubber composition with a shear modulus G* measured at 60° C. of between 0.7 MPa and 1.6 MPa and a measured Tg of between −30° C. and 0° C. The elastomer composition is cured with curing system that includes both a peroxide and sulfur.

摘要: A motorcycle tire that improves straight-line traction performance and also improves turning performance is provided. In a motorcycle tire, a condition of LC/T≦0.08 is satisfied for center blocks, a condition of LM/LC>1.0 is satisfied for the center blocks and intermediate blocks, and the center blocks and the intermediate blocks are either separate from each other in the tire circumferential direction, or overlap each other in the tire circumferential direction with an overlap region of 0.5 LC or less.

摘要: A patch kit and method for repairing a tear in a sidewall of an off-road vehicle tire includes an inside patch component, an outside patch component, and a compressing component for assembling, joining and compressing the inner and outer patch components together with the tire sidewall sandwiched therebetween. The compressing component is a threaded rod and a nut or bolt head to dispose on both ends. The inside and outside patch components are rigid or semi-rigid cupped shells with a hole for the threaded rod, so that the rod may pass through the patches and the tear for compression by tightening a nut. To facilitate tire repair without removing the tire from its rim, a recovery cable is temporarily connected to pull together repair components after they are separately pushed through the tear into the tire.

摘要: A pneumatic tire includes a tread portion provided with a pair of shoulder main grooves adjacent to each tread edge, and shoulder lateral grooves extending from each shoulder main grooves to each tread edge. Each shoulder lateral groove includes an axially inner portion extending from the shoulder main groove with a first angle, an axially middle portion extending from the axially inner portion with a second angle larger than the first angle, and an axially outer portion extending from the axially middle portion with a third angle smaller than the second angle. The shoulder lateral grooves include first and second shoulder lateral grooves alternately arranged in a circumferential direction of the tire. The axially middle portion of the first shoulder lateral groove is disposed axially inwardly of the axially middle portion of the second shoulder lateral groove.
