The new Scalpel 2000 I ordered came with Maxxis High roller 2.35 tires on it. I haven't got the bike yet or test ridden it. The Dealer said he would swap out the tires for something else if I wished. I told him I'd probably keep them; they do look cool on it, but they seem like waay too much tire for this bike. Any opinions here to what I should do?
