The new generation of PZERO Race TLR is the most performing tyre in the Pirelli portfolio as well as being the first tyre with a tubeless technology entirely made in Italy . The introduction of the new SPEEDCORE technology in the 120tpi casing, features the use of a layer of compound mixed with aramid which covers the inner layer of the tyre, improving either the smoothness and the resistance of the rubber. Result: a less stiff but faster tyre. The compound, on the other hand, maintains the same advanced SmartEVO technology, shared with the other high-performance tires in the PZERO range
