A tread portion for tyres for road vehicles comprising a plurality of blocks; at least part of the blocks each comprise a plurality of high hysteresis loss portions (2), which are made of a first compound, and a plurality of low hysteresis loss portions (3), which are made of a second compound. The high hysteresis loss portions (2) and the low hysteresis loss portions (3) are arranged in an alternated position relative to one another. The first and second compound have different dynamic properties in terms of: dynamic modulus at 30°C, tand at 0°C, tand at 30°C and tand at 60°C.
