    摘要： A tire with a tread to which foamed rubber is applied that stably exhibits excellent on-ice performance, which is a combination of braking performance and driving performance of a tire, on the ice road surface from the beginning of its use is provided. The tire includes, in a tread thereof, a surface rubber layer forming at least a ground contact surface of the tread and an inner rubber layer that is adjacent to the inward of the surface rubber layer in the tire radial direction and is formed of foamed rubber, and the elastic modulus of rubber of the surface rubber layer M s is lower than the elastic modulus of rubber of the inner rubber layer M i .

    摘要： A pneumatic tire is disclosed, adapted to highly effectively combine on-ice and on-snow performances. The pneumatic tire includes block groups (G) formed by polygonal blocks (10), which are arranged closely in a tread portion (1). The polygonal blocks (10) are formed by grooves (9) including first groove (9a) with a groove width (W9a) between the polygonal blocks 10 neighboring with each other in the tire circumferential direction. The groove width (W9a) of the first grooves (9a) is larger than a groove width (W9b) of second grooves (9b) between the polygonal blocks 10 neighboring with each other with a zigzag pattern.

    摘要： It is an object of the present invention to provide a pneumatic tire with improved on-snow performance, such as on-snow braking performance, on-snow traction performance, on-snow turning performance, and the like. A pneumatic tire according to the present invention includes, in at least a portion of the tread surface located between both tread ends, one or more main grooves extending in the tire circumferential direction, and a plurality of lateral grooves extending in the tire width direction between the main grooves and/or between the main groove and the tread end, the main grooves and the lateral grooves defining a block row formed by a plurality of blocks, at least one sipe being disposed in each block. Each block has formed therein a first cutaway groove with one end opening into a lateral groove located on one side of the block in the tire circumferential direction and the other end terminating within the block, a second cutaway groove with one end opening into a lateral groove located on the other side of the block in the tire circumferential direction and the other end terminating within the block, and a connecting narrow groove having a groove width narrower than that of the first cutaway groove and the second cutaway groove and connecting the first cutaway groove and the second cutaway groove.
