The PZERO Race 4S TLR is our first ever year-long racing tyre with a tubeless technology able to provide high grip in all kinds of weather and offers increased puncture protection, whilst still maintaining the racing feeling characteristic of our PZERO Race range. This result has been achieved thanks to the SPEEDCOREtubeless technology, our latest evolution in terms of casing constructions, and the SMARTNETSilica which holds the best formulation for wet and chemical grip among our compounds. As with the rest of the PZERO Race range, the PZERO Race 4S TLR is made in Italy in our dedicated Bollate factory.Pirelli SmartNETSilica technology delivers high rolling efficiency, thanks to its natural anisotropic orientation, which reduces heating while increasing elasticity, to help minimise energy dissipation.Enjoy highly reliable wet grip. The wide surface of the silica rod molecules enhances its natural water affinity, delivering confident handling in wet conditions. Puncture resistanc
