Pirellis’ all-arounder race tire, the P Zero Race 4S, is now tubeless-ready and ready to ship. For those unfamiliar, the tire is the middle ground between the full-on race P Zero TLR and the performance training-focused Cinturato Velo.

What is it — Pirelli P Zero Race 4S TLR

The Pirelli P Zero Race 4S TLR is an updated four-season tire from the Italian tire powerhouse. Previously only available in tube-type tires, the new Pirelli P Zero Race 4S TLR is tubeless and hookless rim compatible.

Pirellis P Zero Race 4S uses

The four-season compound offers performance, reliability, and a lively road feel thanks to a 120 TPI nylon casing and nylon breaker to increase puncture protection.

SmartNET Silica Compound

The tread of the Pirelli P Zero Race 4S TLR is made with the SmartNET Silica compound, the same used in the Cinturato Velo tire. The compound is a mix of materials and differs from traditional silica, best known for its grip and performance in wet and cold conditions.

Pirelli explains, “SmartNET Silica compound creates a product with outstanding qualities on wet and typical cold-weather surfaces…its natural chemical affinity for water, and more generally, with low temperatures.”

Speed Core Technology

The Pirelli P Zero Race 4S TLR is equipped internally with Speed Core Technology. The compound has low rolling resistance and offers increased protection against punctures. The compound was first employed in the Pirelli P Zero Race TLR and is a mainstay in Pirelli performance tires.

This is so pedantic but Pirelli should have used their motorcycle tire names for the bicycle tires. They have a clear product delineations that would translate to cycling tires (Diablo Rosso-all around Sport tires, Diablo Rosso Corse-Aggressive track/sport tire that is mostly for track use, Diablo Super Corsa-Track tire that is street legal, Angel GT-/ouring tire) always bugs me that they use the P Zero moniker for 2 wheeled machines plus Diablo sounds super cool. Excellent tires, I’ll give these a go after my Corsa Controls wear out. Was disappointed in the wear/longevity of the Cinturato.

My new Cinteratos are holding up great so far. I weigh 195lbs and have a little under 300miles on them but can still see a bit of the mold seam in the middle of my back tire.

My Cinturato Velos 700/26 were great for the first 1,000 miles with great speed so long as pumped up to 90+psi and only one puncture. I was delighted.
But for the last 300 miles I have had four punctures and the tyres are looking very worn with numerous nicks and cuts.
So I am now considering replacing just 8 months after fitting them

I only race tires that narrow. My Cinturatos are 30s but they have 3000miles on them. I’ve had to use a few dynaplugs in them but I have to do that with every tire I ride. That’s only about 3months of riding for me though
