The Michelin Pilot Alpin PA4 285/30 R21 100W XL FSL 3PMSF is a performance winter tyre featuring a tread with heavy siping. The rubber-studs enhance the road grip. Commanding stabilty and traction. Enhanced grip thanks to the silica compound.
Helio Compound, 3rd generation rubber compound. By reformulating this rubber mix composed of rubber, silica and sunflower oil, we obtain improved grip at low temperatures.
The deep 3D sipes feature various angles which result in:
- a greater number of edges resulting in improved traction,
- breaking the water film to dry the road,
- even more rigid rubber blocks.
The reward is grip and precision in steering.
