My 2003 Yukon XL 4X4 came stock with Firestone Wilderness tires. They are a very good compromise year round. We don't get much snow here but the freezing rain is much more treacherous to drive on and we go skiing every year and I've been happy overall. Quiet and a good ride too. The first set lasted 72K and would have gone 10K more but I put new ones on before a long summer trip for the peace of mind.
