P Zero Race TLR 4S

What's the secret to our tyres? Let's take a look at some of the motorsport-derived technologies applied to our cycling tyres.

The PZERO Race 4S TLR is our 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 our PZERO Race range. This result has been achieved thanks to the SPEEDCORE tubeless technology, our latest evolution in terms of casing constructions, and the SMARTNET Silica which holds the best formulation for wet and chemical grip among our compounds. As the rest of the PZERO Race range, the PZERO Race 4S TLR is made in Italy in our new Bollate factory.

Pirelli SmartNET™ Silica 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 on wet.
Puncture resistance and extensive mileage. Pirelli’s SmartNET™ Silica compound features microscopic rod-shaped particles, that are arranged systematically, rather than chaotically, creating a strong, long-lasting tyre.

The highest-performing tubeless-ready road casing in our range, with a unique design that adds an aramid band within the tyre’s 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.
