removing the rear I guess. Does it make a big difference? I think if someone knows how to take the tire of the rim, then may as well does that for me too...
Road Ride didn't give me much info...</scratching my head>
The issue here is that while it's relatively simple to remove the rear tire, it's actually quite difficult and time consuming to remove the tire from the rim. It's possible on your own, but you're going to need some form of tools, some way of breaking the bead, so on and so forth.
Removing the rear wheel is easy: Just pull the cotter/lock pin out of the rear axel if so equipped, loosen the nut and pull it off (it'll take a lot of force), and then pull the axel out the other side. It can help to tap the axel with something (rubber hammer is best, I've used just about anything under the sun) to get it out. It can also help to have a friend around to help lift the tire, or to jam your foot under it as you tap on the axel to get it free.
After that, push the tire forward, lift the chain off the sprocket, and roll it backwards out of the bike. Make sure to keep track of any spacers, pull the sprocket off, make sure there are no additional free spacers in there, take the tire to Roadrider, and have them patch it or have them replace it.
No big deal.
If i were up in the bay area, I'd have a take off that you could have to get you through, but I'm down in SB. I'm sure if you post up as a fellow rider in need of something to get you through, someone will be able to provide you with a takeoff or something that will help you out until you can get a new tire. A lot of us have old tires floating around that still have a little life left that we'd be happy to donate to a good cause.
