Just the standard Firestones and Town Fairs. They have most of them on hand so you can at least check out the tread pattern in person. Be prepared for a pretty limited selection of tires that are aggressive. You should be able to see most of the AT tires like the BFG TAs, Toyo Open Country, Duelers, Firestone Destinations, and maybe if you are lucky Goodyear Duratracs. I would recommend the Duratracs if you can find them. I am going on a year and a half with mine, they still look new. Great in snow, mud and sand and they look aggressive. they are marketed as an "all terrain" and are nice and quiet.
