Bad weather conditions?
With increased wet grip and puncture protection, this outstanding clincher will deliver an unbeatable ride. Its unique tread design is developed to shed water from your path even faster than the PZero Velo. Wet or dry, the 4S will rise to the challenge.
- The all rounder performing cold weather tyre.
- High marks on all features: rolling, dry & wet grip, puncture protection, mileage, confort.
SmartNet Silica™ is a silicate-based molecule whose configuration differs from traditional silicates: it has no spherical shape but is an elongated stick. The molecule demonstrates a natural self-sorting tendency instead of being randomly positioned within the matrix. Such configuration assures numerous benefits in terms of performance: its longitudinal position positively affects the tyre smoothness allowing high directional performance, thanks also to its high elasticity leading to decreased heat generation and rolling resistance. A further advantage of SmartNet Silica™ is its anti-cluster ability; it spreads evenly and fully within the matrix: this property, added to the natural chemical affinity with water, results in outstanding wet performance. The word ‘Net’ clearly does not appear by chance. A further characteristic of SmartNet Silica™ is its ability to create a genuine particular matrix that binds other compound elements to it. The stability of the molecular weaving is vital for providing reliable performance and contributes to natural puncture protection without adding weight to the tyre structure and prolonging its longevity over time.
Functional Groove Design
The tread, not only having the aesthetic side, inspired by one of the best Pirelli tires for the SSP (World Superbike category), the Diablo Supercorsa. The angles, depth and distance of the tread designed to optimize performance in terms of water discharge, giving grip on dry and wet surfaces, durability and comfort. The tread patterns refers to a lighting flash with very narrow angles in the middle and a wide opening to the sides giving it an advantage of water drainage while keeping it smooth and lowering rubber consumption. The tread is designed with a progressive depth which improves the durability of the tyre and gives great responsiveness even in extreme off camber conditions.
