摘要： A pneumatic tire comprises a carcass layer, a belt layer disposed on the outer side in the tire radial direction of the carcass layer, and tread rubber disposed on the outer side in the tire radial direction of the belt layer. The belt layer is formed by laminating a pair of cross belts having belt angles with an absolute value from 10° to 45° both inclusive and mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° relative to the tire circumferential direction. The distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10≤Gsh/Gcc. The groove depth (Dsh) and under-groove gauge (UDsh) of the outermost circumferential main groove have a relationship satisfying 0.20≤UDsh/Dsh.

摘要： A motorcycle tire has a unidirectional tread pattern formed by a circumferentially extending center main groove, and main oblique grooves each with a branch groove. The main oblique groove has an axially inner end inside a zero-camber ground contacting width and an axially outer end outside the zero-camber ground contacting width. The axially outer end is positioned in a range between 0% and 20% of the developed half tread width from the tread edge. The branch groove is composed of a first inclined part extending from the main oblique groove at an angle θ with respect to the tire circumferential direction, and a second inclined part extending at an angle δ less than the angle θ. When the developed half tread width is axially equally divided into five portions, the land ratio of each of the five portions is 75% to 85%.
