The new generation PZERO Race TLR is Pirelli's best performing racing tire and is also the first tire with tubeless technology made entirely in Italy. The introduction of the new SPEEDCORE technology in the 120tpi carcass involves the use of a layer of compound mixed with aramid that covers the inner layer of the tire, improving the smoothness and resistance of the rubber. Result: a less stiff but faster tire. The compound, on the other hand, retains the same advanced SmartEVO technology, which is shared with the other high-performance tires in the PZERO range.
