is there such a thing. i'm riding an 06 Uly right now and love this bike. but it's running street/sport tires. it handles dirt and gravel like a champ with these tires and i was wondering what kind of options are out there for a dualpurpose tire in a 17" i know this is opening a can of worms but what do you guy suggest. i do alot of commuting miles for work but i'm just as likely to take a roundabout way home that usually turns into management area access roads before i get home.
