    Abstract: A tire having a tread includes an outer tread layer and an inner tread layer. The inner tread layer includes one of a first elastomeric compound and a second elastomeric compound. The outer tread layer includes the other of the first and second elastomeric compounds. The second elastomeric compound has a lower rolling resistance and greater resistance to treadwear than the first elastomeric compound. The inner tread layer increases in thickness across at least a widthwise portion of the outer tread layer with a maximum thickness of one of the inner tread layer and the outer tread layer occurring near at least one of a first shoulder and a second shoulder of the tread. As the tread wears, the inner tread layer defines a greater proportion of a running surface of the tread.

    Abstract: 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.
