For sure they aren’t as good as a winter tire
Maybe you don’t plan on using your car in the winter, or maybe where you live the winter is dry, so you don’t need a dedicated winter tire. Not that this is anyone’s fault or something but the weather is up for big surprises nowadays, so you never know for sure what’s in store for tomorrow.
Tire manufacturers took all this into consideration and created the M+S all-season tires, good not only on a hot summer day but also in the winter. Furthermore, the 3PMSF (3 Peak-Mountain Snow Flake) symbol can be found on an all-season tire as well, meaning it can perform on icy surfaces as well. And that’s what Tire Rack wanted to see: just how efficient these products are in a proper winter context.
The testers are Michelin CrossClimate+, Pirelli Cinturato P7 All Season Plus, Vredestein Quatrac 5, and Goodyear Assurance WeatherReady.
Also, here's a wet comparison between a budget tire vs. a new tire vs. a worn tire just to remind you the importance of the rubber you put on your rims.
