Abstract
The pneumatic tire (1) comprises at least three circumferential grooves (22) extending in a tire circumferential direction in a tread portion (2), and at least four ribs (23) defined by the circumferential grooves (22), the at least four ribs (23) extending in the tire circumferential direction. At least two of the ribs (23) protrude outward in a tire radial direction beyond the profile line (L) of the tread surface when viewed in the meridian cross section. The protruding amount (G) of the at least two ribs (23) decreases in order from a first side in a tire width direction to a second side.
Claims9
A pneumatic tire comprising:
- at least three circumferential grooves extending in a tire circumferential direction in a tread portion;
- and
- at least four ribs defined by the at least three circumferential grooves, the at least four ribs extending in the tire circumferential direction;
- at least two ribs of the at least four ribs protruding outward in a tire radial direction beyond a profile line of a tread surface when viewed in a meridian cross section, the at least two ribs being provided adjacent to one another and interposed by one of the at least three circumferential grooves;
- and
- a protruding amount of the at least two ribs decreasing in order from a first side to a second side in a tire width direction and a difference between a maximum value and a minimum value of respective protruding amounts of the at least two of the ribs being not less than 0.4 mm and not greater than 0.8 mm;
- wherein the at least two ribs include a shoulder side rib defined as an outermost rib of the at least four ribs in the tire width direction.
A pneumatic tire comprising:
- at least three circumferential grooves extending in a tire circumferential direction in a tread portion;
- and
- at least four ribs defined by the at least three circumferential grooves, the at least four ribs extending in the tire circumferential direction;
- at least three ribs of the at least four ribs, adjacent to one another, protruding outward in a tire radial direction beyond a profile line of a tread surface when viewed in a meridian cross section;
- and
- a protruding amount of the at least three ribs decreasing in order from a first side to a second side in a tire width direction and a difference between the respective protruding amounts of the at least three ribs adjacent to one another is 0.3 mm to 0.8 mm, both inclusive;
- wherein the at least three ribs include a shoulder side rib defined as an outermost rib of the at least four ribs in the tire width direction.
