Continental Tire is one of the oldest and largest tire companies in the world. It is actually a German company, with U.S. headquarters in South Carolina. They also own the General Tire company. They provide the OEM tire for many German makes such as Audi, BMW, Mercedes-Benz, and Porsche. You will find that most of their tires have the word "Contact" in the name, and they have even trademarked them, for example, ExtremeContact™.
For 2017, we added the Continental WinterContact SI. A slightly different model not sold in the U.S., the WinterContact TS 860, was recently rated first place in both ADAC's 2017 winter tests as well as in German magazine Auto Bild's tests. Initial reviews of the WinterContact SI for sale in the U.S. are off to a decent start, though there are minor differences between the two Continental WinterContact models. The tread pattern is based on the same principle, though Continental has many marketing labels applied to the TS 860 (Cool Chili, Liquid Layer Drainage, Snow Curve+) that are not present in the marketing labels for the SI (PolarPlus+). Therefore, we aren't recommending the SI as one of our top tires, but it's worth considering given Continental's experience based in winters of Northern Europe.
