Pirelli P ZERO™ Race 4S TLR Tubeless Ready Tire
The Pirelli P ZERO™ Race 4S TLR is the first all-season racing tire from Pirelli designed to offer maximum grip in all weather conditions, while preserving the typical performance of a racing tire from the P ZERO™ Race range.
Thanks to the combination of SPEEDCORE™ tubeless technology, the latest evolution of Pirelli’s casing, and the SmartNET™ Silica compound, this tire guarantees excellent grip on dry and wet surfaces, greater safety in difficult conditions, and superior protection against punctures, without sacrificing smoothness and responsiveness.
Like all models in the P ZERO™ Race range, the P ZERO™ Race 4S TLR is entirely made in Italy, at Pirelli’s Bollate factory.
SmartNET™ Silica Compound
A direct result of Pirelli’s experience in Motorsport, the SmartNET™ Silica is a patented formula that brings racing-level performance to cycling.
Unlike traditional silica with spherical molecular structure, SmartNET™ Silica uses elongated silica molecules, allowing a new level of sophistication in the tread compound. This enables:
Maximum grip and smoothness on both dry and wet surfaces
Better handling, thanks to the orientation of the compound in the rolling direction
Increased mechanical strength of the tread
The optimized interaction between the Silica and other compound components, such as directly dispersed aramid fibers, further enhances:
SPEEDCORE™ Structure
The SPEEDCORE™ is a tubeless-ready structure developed by Pirelli (patent pending) for high-performance cycling tires, and represents the most advanced TLR technology ever created by the brand.
Derived from Pirelli’s expertise in the automotive sector and made possible by the new Italian production plant near Milan, the SPEEDCORE™ construction includes:
This layer lines the inside of the tire and allows:
All these elements decisively contribute to the overall performance of the tire, making it ideal for competitive use and road cycling in variable weather conditions.
