I am looking for some new tires and really like what hear about the BF Goodrich KM2. As I do use my 4 runner to ski we do go thru some deep snow, ice and I have a long climb up to our ski area whereas the roads are pretty bad. Discount tire recommended the DuraTrac for the snow part. We also like to 4 wheel rocks in AZ, Utah and Colorado. Thanks for your input!
