A pneumatic tyre for a vehicle having a rolling direction when mounted on the vehicle, the tyre comprising a tread portion (10), inside and outside shoulder portions (20,30), the inside shoulder portion (20) being closer to the centre of the vehicle when the tyre is mounted and the outside shoulder portion (30) being located opposite to the inside shoulder portion (20). The outside shoulder portion (30) comprises a plurality of depressions (80) arranged sequentially with respect to the rolling direction of the tyre, wherein each depression (80) has a length in the rolling direction and a width perpendicular to it and the ratio of length to width in each depression (80) is ‰¥0.65:1 to ‰¤1:1, each depression (80) having a depth of ‰¥ 1 mm, and wherein the tread portion (10) comprises a rubber material with a first glass transition temperature of ‰¥ -25 °C to ‰¤ -5 °C and a first loss factor tan ´ ‰¥ 0.25 to ‰¤ 0.50 at 0° C and the outside shoulder portion (30) comprises a rubber material with a second glass transition temperature of ‰¤ -40 °C and a second loss factor tan ´ ‰¥ 0.1 to ‰¤ 0.3 at 0° C, the first loss factor being greater than the second loss factor.
