Pirelli P Zero Velo 4S Road Bike Tyre

Find yourself riding in poor weather conditions? Then the Pirelli P Zero Velo 4S is the road bicycle tyre for you! he knowledge and know-how gained through years of experience in various disciplines of motorsport have lead to the creation of the 4-seasons Pirelli P Zero Velo 4S tyre. The same tyre technologies used in motorsport are applied to the Pirelly P Zero Velo bicycle tyre, only with an even stronger focus on superior grip and puncture resistance. This has led to a slightly thicker sidewall and main tread design. The core of this tyre still is Pirelli's own SmartNET Silica rubber compound. This compound offers the Pirelli P Zero 4S low rolling resistance, good puncture resistance and durability, and high levels of grip in even the poorest conditions. All this combined makes the Pirelli P Zero Velo 4S into the ultimate 4-seasons tyre!

SmartNET Silica®
Pirelli’s patented state of the art compound made using a unique formula. Developed from years of motorsport experience including the pinnacle of motorsport: Formula 1. SmartNET Silica offers cyclists a truly uncompromising road cycling experience. It ensures low rolling resistance, grip on both wet and dry road surfaces, durability, puncture resistance, and a low overall weight to boot.

The unique longitudinally shaped silica particles manage to align and place themselves evenly throughout the compound. This offers a predictable response from the tyre and keeps the rolling resistance low. This in contrast to many tyres which often have irregular structures. The SmartNET Silica compound responds to a wet road surface. The silica and other particles in the compound align to create a strong lattice. This improves both durability and puncture resistance.

FGD - Functional Groove Design
The Pirelli P Zero Velo and P Zero Velo 4S both feature FGD (Functional Groove Design). This groove technology are inspired by motorsport and virtually identical to the grooves on the SSP tyre (SuperSport class in the World SuperBike racing competition): the Diablo Supercorsa. The tread has multiple functions. It helps you get the most from the tyre when it comes to water dispersion, dry and wet grip, durability, tyre response, comfort, and handling. The Functional Groove Design is reminiscent of a lightning bolt, which has several different reasons.

The tread has very acute angles in the middle with a clear sideways opening for water to be drained through, as well as for suppleness and user-friendliness. The tread design has been engineered with a progressively increasing depth intended to improve the rebound of the tyre and improve the responsiveness of the tyre, even in sharp turns at high speed. The positioning of the grooves ensures that you’ve got several different contact points between the road and the tyre. This helps you get the most from the tyre.

ICS - Ideal Contour Shaping
The shape of the tyre is just as important as the materials and tread pattern. Pirelli has used CAD software, repeated simulations, and follow-up analysis to optimise the contour and shape of the tyre. This optimises the contact points between the tyre and road surface, getting the most from the compound and tread design. Grip, stability, and a responsive yet controlled reaction to any road surface. The tyre performs equally well whether you’re on the flats, coming down a fast descend, or taking sharp turns.
