Abstract
The present technology pertains to a pneumatic tire having an asymmetrical pattern, which is formed by grooves, formed on a tread portion. A ratio SW/OD between the total width SW and the outer diameter OD of the pneumatic tire satisfies SW/OD≦0.3. A groove area ratio in a ground contact region G in the tread portion is GR, and a range from a tire equator line CL to the vehicle side in the ground contact region is a tire inside region Ai and the groove area ratio in the tire inside region Ai is GRi, and a range from the tire equator line CL to the opposite side of the vehicle side in the ground contact region is a tire outside region Ao and the groove area ratio in the tire outside region Ao is GRo, the ground contact region satisfies 10%≦GR≦25%, GRo.
