PNEUMATIC TIRE

摘要

A pneumatic tire is provided with a pair of first land sections formed between shoulder main grooves and center main grooves, a second land section formed between the center main grooves, and a pair of shoulder land sections formed on the outside of the shoulder main grooves in a tire width direction. The first land sections and the second land section swell outward in the tire radial direction from a basic tread profile line that smoothly connects ground contact surfaces of the pair of shoulder land sections. A swelling amount of the first land sections that swell from the basic tread profile line is larger than a swelling amount of the second land section.
