I'm looking for some input from all of you that do trail runs in snow. I'm working on organizing a run for the first weekend in January in northern Wisconsin...so hopefully there will be a good cover of snow on the trail. My problem is, I'm running open 3/4 ton diffs and 33" AT's. I plan on stepping up to 35's in the future, but am debating getting a pair of tire chains for this run and possibly other situations. So, those that have them, convince me I need or don't need them. Oh, I've got a pair lined up for $40. /forums/images/graemlins/thinking.gifAlso...those that use them, do you have them on the front or rear?
