The invention is a tyre for a vehicle comprising a tread (2), in which the central portion of the tread (2) comprises at least two rubber mixtures (221, 222), making up at least 90% of its volume. The first mixture (221) is radially outside the second mixture (222) and makes up at least 40% and at most 60% of the volume of the central portion. The second rubber mixture (222) has a Shore hardness DS2 at least equal to 5 plus the Shore hardness DS1 of the first mixture (221). The second rubber mixture (222) has dynamic losses at a temperature of 0°C and at a temperature of 23°C at least equal to those of the first rubber mixture (221).
