And they do. I've seen far less worthy machines on the track. You're not going to set any records, (well, speed records anyway...) but that's not the point of roadracing.

Fatter does not always equal faster. You can, in fact, go backwards. Depending on the profile of the tire, and the stiffness of the carcass, stuffing a fatty on your skinny-ass rim, can result in a smaller contact patch.

These are not the droids you are looking for.

You'll be better served with tires that fit the rims, and paying very close attention to the pressures you run, and under which conditions you run them. In other words, buy a little fucking note book, and write that shit down.

That said, there may be a slightly over-sized tire out there that will give you more grip. Then again, more grip comes with slower transitions. So......

Find out who the fast guy is, and run what he's running. But wait, you ain't him. Shit. Those tires may not work for you. Now you are seriously fucked. Your tires are too big, bike handles like a wheelbarrow, and girls won't go out with you.
