I just took the first real ride (about six miles) on my Western Galaxy Flyer (about '76 is my best guess; found "176" in one place and "76" in another) this morning, and discovered that the reason the rear tire was rubbing on the fender is apparently because the tire is crooked. It was a nice ride, other than the lil bounces and having to keep the same pedal down whenever I coasted

I have read (briefly) about "truing the tire" and was wondering if someone can tell me how to do this. I'm trying to learn the basics of bike maintenance myself so I don't have to pay to have anything done (okay, I'm cheap, but I'm inventive).

Can anybody help me out?
