??? So I've been told that mud tires are not so great on icy winter roads. I have never had them on except this summer, and I love em' thus far. The tire store folks told me they can sipe them for better winter traction and icy road performance. The idea seems to make sense as you get more small edges to bite the road. Anybody have any actual experience with this? Does it do bad things to the tires themselves?? :-\ Thanks.
