Pirelli Launches the P ZERO Race 4S TLR Road Bicycle Tire, The All Season Tubeless Tire that Performs in any Weather Condition

May 3, 2023

New SPEEDCORE technology that makes the tire roll smoothly and with low risk of puncture SmartNET Silica compound: perfect on cold or wet tarmac, offering all-round performance Produced in the renovated Milano-Bollate facility

Milan (Italy), May 3, 2023 /ENDURANCE SPORTSWIRE/ – Pirelli presents the P ZERO Race 4S TLR road bicycle tire, the tubeless version of the Pirelli all season tire, produced in the renovated Milano-Bollate facility. The new all-round tire follows the success of the P ZERO Race 4S clincher version.

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


The P ZERO Race 4S TLR, in fact, 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.


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 compound containing Aramid particulate. SPEEDCORE technology favours the hold of air, has low resistance to rolling 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 casing to roll smoothly and the combination with the SmartNET Silica compound – which favours grip even on wet surfaces typical of autumn and winter – result in a product to use all year long, with all-round performance.


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, 30-622 and soon 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 of the P ZERO Race family.
