Tire having a tread (10), the tread further comprising a first tread cap layer (3) intended for contacting a road when driving, wherein the first tread cap layer comprises a first rubber composition. Moreover, the tread comprises a second tread cap layer (4) arranged radially inside of the first tread cap layer and supporting the first tread cap layer, wherein the second tread cap layer comprises a second rubber composition different from the first rubber composition. According to the invention, a rebound resilience of the first rubber composition, determined at a temperature of 0°C according to DIN 53512, is within a range of 10% to 25%, and a rebound resilience of the second rubber composition, determined at a temperature of 0°C according to DIN 53512, is within a range of 20% to 35%, wherein said rebound resilience of the first rubber composition is at least 5% lower than said rebound resilience of the second rubber composition. Moreover, a rebound resilience of the first rubber composition, determined at a temperature of 100°C according to DIN 53512, is within a range of 45% to 65%, and a rebound resilience of the second rubber composition, determined at a temperature of 100°C according to DIN 53512, is within a range of 60% to 75%, and wherein said rebound resilience of the second rubber composition, determined at a temperature of 100°C, is at least 3% higher than said rebound resilience of the first rubber composition, determined at a temperature of 100°C.
