Malgré son apparence très agressif il est très silencieux et très confortable sur l’autoroute. Je rachète n’importe quand !

Frequently asked questions

What is the difference between an all-season tire and a winter tire?

An all-season tire offers a versatile compromise for year-round driving, but its rubber hardens below 45°F (7°C), reducing grip on snow and ice. A winter tire, by contrast, stays flexible in extreme cold thanks to a specialized rubber compound and deeper tread sipes, delivering better traction, shorter braking distances, and improved handling on winter roads.
