Next week I'll be diving into the experience of changing my own tires. I got a flat on Friday and, after checking prices on tires at Cycle Gear (the best game in town) and a few online retailers, I found I can save $55 per rear tire if I order it and then mount it myself!! I've got a bead breaking press (hand powered, not machine powered) on order and I've already got some tire irons and rim savers. I may end up ordering longer tire irons but I'm pretty sure I can manage with what I've got. I'll post up pictures once I've done it. Tanman has done it and has sworn against doing it again but I'm thinking with the rim savers (plastic pieces that clip on the rim to protect it from being damaged by the tire iron) I won't be so upset about the ordeal. Wish me luck!
