Hello, I have the following problem: I had equipped my T4 Multivan with 4x new Michelin PA for the winter of 2009/2010 and drove to my surprise like on rails. Snowy climbs, which I could not cope with before with different cars (also front-wheelers) were suddenly no longer a problem with the Michelin. Well, and so I looked at the current winter season with great serenity, the profile had also lost only 3 mm. And now k at the shock: I’m just slipping around as if I had some awesome summer tires on it! Interesting here is that the grip increases after a few kilometers but again. Ok, you think, maybe there had to be icy snow pushed out of the profile again. Just, why was that then no problem last winter? It’s really damn stupid to slip the first kilometers like on eggs and almost not get out of a parking bay, in which one still an hour before So, I haven’t experienced such a stark difference after just one winter and 3 mm less profile in more than 30 winters of my driver’s life. I’ve driven enough winter tires a second, some even a third season. Above all, this phenomenon is new to me to have to drive for miles before the grip comes back, but I put the box off for a short while, immediately gone. Does anyone of you know that? Is this hanging with the icy temperatures together at the moment? Or? Thanks a lot!!! Thommy
