Abstract
In a pneumatic tire, an outer second land portion, a center land portion, and an inner second land portion have a road contact surface that partially bulges toward the outer side in a tire radial direction from a reference contour line of a tread profile in the cross-sectional view in the tire meridian direction. Additionally, a groove width Wg1 of an outer shoulder main groove, a groove width Wg3 of an inner center main groove, and a groove width Wg4 of an inner shoulder main groove have a relationship of Wg3<Wg1<Wg4, 1.05≤Wg1/Wg3≤1.25, and 1.10≤Wg4/Wg3≤1.30.
Claims15
A pneumatic tire having an indicator designating a mounting direction with respect to a vehicle, the pneumatic tire comprising:
- an outer shoulder main groove, an outer center main groove, an inner center main groove, and an inner shoulder main groove extending in a tire circumferential direction;
- and
- an outer shoulder land portion, an outer second land portion, a center land portion, an inner second land portion, and an inner shoulder land portion defined by the main grooves,
- the outer second land portion, the center land portion, and the inner second land portion comprising a road contact surface that partially bulges toward an outer side in a tire radial direction from a reference contour line of a tread profile in a cross-sectional view in a tire meridian direction, and
- a groove width Wg1 of the outer shoulder main groove, a groove width Wg3 of the inner center main groove, and a groove width Wg4 of the inner shoulder main groove having a relationship of Wg3<Wg1<Wg4, 1.05≤Wg1/Wg3≤1.25, and 1.10≤Wg4/Wg3≤1.30.
