Pirelli launches tubeless version of P ZERO Race 4S all-season tire

  • Ron 

Pirelli has launched the P ZERO Race 4S TLR road bicycle tire, the tubeless version of the renowned Pirelli all-season tire.

The new tire has remained aesthetically unchanged from the clincher version and incorporates new technologies and prior patents that capitalize on Pirelli’s experience in the high-end cycling sector.

All Season Compound

The P ZERO Race 4S TLR features a tread made with the award-winning SmartNET  Silica compound, the same used in the CINTURATO Velo tire. A Pirelli patented mix of materials, SmartNET is a silica-based molecule whose configuration differs from traditional silica molecules: its elongated stick form has a natural self-aligning tendency, providing numerous advantages in terms of performance. Among these, the most prized for use in the  all-season tire is certainly its natural chemical affinity for water, and more generally, with low  temperatures, which creates a product with outstanding qualities on wet and/or typical cold weather surfaces.

SPEEDCORE compound with ARAMID

Combined with the external SmartNET Silica, the structure of the P ZERO Race 4S TLR is equipped internally with the innovative SPEEDCORE technology, which uses a layer of a compound containing Aramid particulate. SPEEDCORE technology favors the holding of air,  has low rolling resistance, and offers increased protection against punctures. This new technology was developed thanks to Pirelli’s experience in the field of racing compounds. It was introduced for the first time on the market with the P ZERO Race TLR tire, also a product of the Milano-Bollate facility.

In the case of an all-season tire like this one, the use of SPEEDCORE technology makes the tire roll smoothly and, in combination with the SmartNET Silica compound – which favours grip even on wet surfaces typical of autumn and winter – results in a product to use all year long, delivers all-round performance.

The Tire With The “Racing” Feel 

The new P ZERO Race 4S TLR tire is the perfect choice for those who want a high-performing tire, for competitions or training, ideal all year round: high-performing and fast in summer, high grip and resistant in winter, with that “racing” feeling typical of the Pirelli “Race”  family.

P ZERO Race 4S TLR is already available in 28-622 and 30-622 and will soon sell in size 32-622 too.  It completes the line by complementing the P ZERO Race clincher tire and tubeless type – to match respectively with the SmarTUBE air chamber and P ZERO sealant – and the P  ZERO Race SL TLR, the lightest tire of the P ZERO Race family.
