The second season of Chiron is the one I use. In point of fact, this is the first winter that these wheels have experienced snow, frost, ice, and snowdrifts. The wheels have both dissatisfied and distressed me. Before this winter, I spent the previous five seasons driving the Nordman 5 SUV. I climbed everywhere, whereas Zad never even went into a skid. It continually lathers on these, whether it be at traffic lights, in the yard, or simply on a slippery road. When you give it a hard acceleration, the back axle will break almost quickly. The loading time has been reduced slightly.
