The first compound () is radially on the outside of the second compound () and makes up at least 40% and at most 60% of the volume of the central part. The second rubber compound () has a Shore hardness DS2 at least equal to 5 plus the Shore hardness DS1 of the first compound () and dynamic losses at a temperature of 0° C. and 23° C. that are at least equal to those of the first rubber compound (). The axially outer parts of the tread are made up of a third compound () capable of touching the ground, having a stiffness and a hysteresis that are lower than those of the first compound.
