My 98 Sportsman is still on its original Carlisle AT489 tires and it's finally time to replace them. We had my uncle's and my sportsman at the dealer yesterday for regular service and I checked on new tires. The dealer told me they had a brand-new set of take-off wheels and tires from a new sportsman they sold to a guy who upgraded. He'll give me the set for $400. I'm not sure what brand of tires come stock now, but I guess they're the same as my uncle's 2008. I wouldn't argue with new wheels, either, since mine are looking pretty rough with a few dings and some light corrosion.
