Michelin pilot hx mxm4 all season tires failed in 1" wet snow condition. Michelin isrefusing to accept tires do not work in snow. They were sold as all season and have a m+s on the side for mud and snow. My car slid off the crown of the road into the grass. The conditions were not icy. All of our other cars had no trouble. I want michelin to compensate me for the snow tires I had to buy and install so that I could drive in snow fo a total of $800.
