A new one looks like this.
Excuse the rocks. It's after driving on a National Park forest road.
So, it doesn't have full depth sipes that some people claim the CC2 have from their "expert analysis" like Justin Bieber, the engineer, from Engineering Explained youtube video (which was merely him regurgitating Michelin marketing notes).
The shoulder sipes have become partial. The center tread "stepped" sipes are gone... it's looking more like the original CrossClimate/CrossClimate+
Performance in the dry has already dropped off, since I can get traction control kicking in accelerating from a stop to merge onto the highway. If I'm taking a curved on-ramp hard, stability control is intervening.
I seriously hope winter traction doesn't take a dump... but I do have cable chains, just in case.
