Cooper Weather Master Sio2 225/60 R15 96H

The Cooper Weather-Master Sio2 winter tire is positioned as a high-performance model for passenger cars, designed for use in regions with very cold climates. It stands out from most analogs with a combination of characteristics from classic winter and sports tires, differing in reliable grip on snow and ice, along with increased steering accuracy and stability on cleared and wet roads.

The tire's tread has a directional pattern formed from large blocks and V-shaped grooves, which optimize the transmission of traction forces and improve directional stability. In the central part, the elements form a composite continuous longitudinal rib, which provides precision reactions to steering wheel turns and even load distribution. These properties are largely preserved even on the most slippery winter surfaces — numerous lamellas of varying depth create thousands of sharp edges that "bite" into snowy and icy surfaces. The structure of their arrangement contributes to a short braking distance and confident acceleration dynamics.

However, the key feature of the model is the Sio2 Silica Formula compound, borrowed from the brand's sports tires. Its composition uses highly dispersed silicon dioxide, which gives the mixture increased flexibility at low temperatures and simultaneously improves grip on wet surfaces. The Cooper sports tires "shared" the carcass, which is reinforced with a multi-layer synthetic cord with optimized thread density. Such a design increases resistance to mechanical damage and maintains the shape of the tire under high loads and sharp maneuvers.

Key features of the Cooper Weather Master Sio2:
- directional V-shaped tread provides confident grip on snow and ice;
- compound with special composition retains elasticity at low temperatures and improves grip on wet surfaces;
- multi-layer synthetic cord increases resistance to loads and deformations.
