摘要： A rim guard of a tire has a top, an inner surface, and an outer surface. A contour of the inner surface is represented by a circular arc, and the circular arc has a radius of not less than 20 mm and not greater than 30 mm. A contour of the outer surface is represented by a circular arc, and the circular arc has a radius of not less than 100 mm and not greater than 500 mm. In a radial direction, a position of an outer edge of the outer surface coincides with a cross-sectional width specified position, or the outer edge of the outer surface is located outward of the cross-sectional width specified position.

摘要： A pneumatic tire excellent in resistance to uneven wear, and crack resistance of a groove is provided. A position, on an equator plane, of a tread surface 20 of a tire 2 is represented as a point Pc. A position, at a maximum width, of an axially outer side surface 6a of a sidewall 6 is represented as a point Pe. A position that is a mid-point, in the radial direction, between the point Pc and the point Pe, and that is on the axially outer side surface 6a, is represented as a point Pd. When an internal pressure is enhanced from an Internal pressure that is 0.05 times a normal internal pressure P to the normal internal pressure P, a value Fs of difference in amount of protrusion between an amount of protrusion Dd (mm) at the point Pd and an amount of protrusion De (mm) at the point Pe is calculated according to mathematical expression (1) in which a nominal width is represented as W (mm). The value Fs of difference in amount of protrusion is greater than −0.4 and less than 0.5. Fs=((Dd−De)/W)×100 (1)

摘要： A pneumatic tyre includes a carcass extending between bead cores disposed in respective bead portions through a tread portion and sidewall portions, and bead apex rubbers each extending radially outwardly from the respective bead cores, each bead apex rubber having an inner side surface in a tyre axial direction. In a tyre cross-section under a standard inflated state, a ratio h1/H of a carcass-maximum-width height h1 to a carcass-maximum height H is equal to or less than 50%, and in at least one bead portion, an angle of a tangent line touching the inner surface of the bead apex rubber at an intersection of a tyre radial reference line passing a rim-width location of the standard wheel with the inner side surface of the bead apex rubber is in a range of from 55 to 75 degrees to the tyre radial reference line.

摘要： [Object] A pneumatic tire 2 that allows achievement of reduction of rolling resistance without taking influence on a mass into consideration, is provided.[Solution] A profile OL of the tire 2 includes a ground-contact surface 46 and a pair of side surfaces 48. In the profile OL, a zone from a point PB to a point PW is formed by three arcs. The arcs are a first arc, a second arc that extends almost outward from the first arc in the radial direction, and a third arc that extends almost outward from the second arc further in the radial direction. A ratio of a radius R2 of curvature of the second arc to a radius R1of curvature of the first arc is greater than or equal to 1.45 and not greater than 3.26. A ratio of a radius R3 of curvature of the third arc to the radius R1 of curvature of the first arc is greater than or equal to 0.45 and not greater than 0.56. Each sidewall 8 of the tire 2 has a first recess 50a and a second recess 50b that are recessed inward from the side surface 48.

摘要： In an internal pressure state where an internal pressure that is 0.05 times a normal internal pressure P has been increased to the normal internal pressure P, amounts of protrusions at points Pa, Ph, Pd, and Pe are represented as Da (mm), Dh (mm), Dd (mm), and De (mm), respectively. A sum Fa (((Dd+De)/W)×100) of the amounts of protrusions for each sidewall 6 satisfies mathematical expressions (2) and (3) in which an aspect ratio A is used, and a difference Gs (((Da−Dh)/W)×100) in the amount of protrusion for a tread 4 satisfies mathematical expressions (5) and (6). 0.02626×A−1.8615

摘要： A rim protector 40 of a tire 2 projects from a reference surface 44 of each side piece 38. The rim protector 40 has a first inclined surface 50 and a second inclined surface 52. A profile of the reference surface 44 includes an outer circular arc and an inner circular arc which are tangent to each other at a reference position. A first circular arc of the first inclined surface 50 is tangent to the outer circular arc, and a second circular arc of the second inclined surface 52 is tangent to the inner circular arc. A ratio of a height H relative to a cross-sectional height SH is equal to or greater than 0.27 and equal to or less than 0.34. A projecting length W is equal to or greater than 12 mm and equal to or less than 18 mm.
