When i bought my 2002 Chevrolet 2500HD i made a bad decision and went with the the road tires that are classified as mud and snow, but dont have enough bite. I shoudve gotten the lugged off road tires they offer. Well, anyway, winter is approaching and im going to replace them a little early, and i was wondering if anybody had some recommendations. id like to jump up a size or two and i would like something more aggressive than the tires i have now. any suggestions?
