Yeah I agree. It is best to change tires as the seasons change. But $$$$ is an issue for some people. So, in order to compensate, get the Perelli Asemetrico's Zero's and you will be set all year long. I have them on my X and I love them. I live in Chicago and it snow's pretty good here. I've never had a spin out or lost any control at all. The only thing is that the inner part of the rear tires seem to wear out quicker then the rest. I'm just going to buy 2 new rear as the front are still brand new. I think I will get about 30k on the rear set and then its time for new ones. But then its the X's suspension that is at fault. I have the 01 sport 4.4i.
