Abstract
A pneumatic tire 2 has a marking on each sidewall 8 thereof. A large number of dimples 62 are formed in a region between the marking and a rim protector 34. These dimples 62 are arranged along a circumferential direction. These dimples 62 form a row. The row includes: (1) dimples each having a plane shape of a circle; or (2) dimples in each of which a plane shape is substantially a rectangle, and a ratio of a length in the circumferential direction to a width in a radial direction is equal to or greater than 1.0 and equal to or less than 3.0.
Claims6
A pneumatic tire comprising a marking on an axially outer surface of a sidewall in each side portion of the tire,
- wherein
- a processible region positioned on the axially outer surface of one or both of the sidewalls and inward, in a radial direction, of the marking includes two rows formed by a large number of dimples arranged in a circumferential direction,
- a width, in the radial direction, of the processible region is equal to or greater than 12.0 mm and equal to or less than 17.0 mm,
- the dimples forming the first radially outer row have a planar shape that is rectangular with the ratio of the length in the circumferential direction to the width in the radial direction being equal to or greater than 1.0 and equal to or less than 3.0, and the width in the radial direction being equal to or greater than 7 mm and equal to or less than 10.0 mm, and
- the dimples forming the second radially inner row are
- (1) dimples having a planar shape that is circular and a diameter equal to or greater than 2.0 mm and equal to or less than 10.0 mm, or
- (2) dimples having a planar shape that is rectangular with the ratio of the length in the circumferential direction to the width in the radial direction being equal to or greater than 1.0 and equal to or less than 3.0, and the width in the radial direction being equal to or greater than 2.0 mm and equal to or less than 10.0 mm.
