The PZERO Race 4S TLR is pirelli's first ever year-long racing tyre with a tubeless technology able to provide a high grip in all kinds of weather and an increased puncture protection, still maintaining the racing feeling characteristic of their PZERO Race range. This result has been achieved thanks to the SPEEDCORE tubeless technology, their latest evolution in terms of casing constructions, and the SMARTNET Silica which holds the best formulation for wet and chemical grip among their compounds. As the rest of the PZERO Race range, the PZERO Race 4S TLR is made in Italy in Pirelli's new Bollate factory.Featuring Speedcore, the highest-performing tubeless-ready road casing in their range, with a unique design that adds an aramid band within the tyres rubber layer. This new structure adds strength and support to the tyre casing but retains a supple feel for minimal rolling resistance and maximum grip, compared to a tyre with a full bead-to-bead aramid construction. The tyre also features a 120tpi nylon casing for added puncture protection and maximum security.Size: 700c x 28mmApprox weight: 330gCasing: 120TPI Speedcore Tubeless Ready
