PROBLEM TO BE SOLVED: To satisfy both the ice braking property and wet road braking property, and to secure stable travel performance on a general road surface and a snow and ice road surface by using a rubber composition containing a water- soluble resin at least on one layer in a tire split with the ground rubber of a tread into many layers in the tire peripheral direction. SOLUTION: A carcass 1 and a belt section 2 arranged in the peripheral direction on a crown section are provided, and a tread section is constituted of the base rubber 3 arranged on the inside in the tire radial direction and the cap rubber arranged on the outside in the tire radial direction. A cap section is formed with a trichotomized tread arranged with rubbers 4a, 4c at both shoulder sections and a rubber 4b at a center section. At least one layers of the divided tread layers contains a water-soluble resin. Short water-soluble fibers with the length of about 10 mm or below are preferably used for the water-soluble resin. This tire has excellent performance in the wet road braking property, ice baking property, controlling stability, and snow controlling stability. |
