A pneumatic tire is disclosed comprising a tread (10, 100, 200) with a ground engaging surface, the tread being a dual-layer tread made of or comprising a first layer (11, 101, 201) comprising a first tread compound having a loss compliance LC(1) and a loss modulus E"(1) and a second layer (12, 102, 202) comprising a second tread compound having a loss compliance LC(2) and a loss modulus E"(2); wherein both of the loss compliance LC(1) and LC(2) and wherein both of the loss modulus E"(1) and E"(2) are determined by a dynamic mechanical analysis (DMA) system at a frequency of 10 Hz under pre-strain of 10% and dynamic strain of 2.5% within a temperature sweep from 0 to 130 °C. The volume ratio of the second tread compound relative to the first tread compound in the tread is in the range of from 0.5:1 to 10:1. When the tread temperature is in the range of from 5 to 50°C, LC(1) > LC(2), and/or when the tread temperature is in the range of from 0 to 20°C, E"(1) > E"(2).
