I have just discovered that one of my tires is bald to the point of nearly having a hole in it. I thought that until I am able to get into the shop to get new tires in a couple of days, I could reinforce the spot to prevent further punctures in that area. I decided that since I have no thick rubber, I would use a strip of plastic from a vitamin bottle. I cut a long strip and rounded the edges, and fit it into the tire, two layers thick, then inflated the tire as usual. It seems to be fine, although I haven't ridden on it yet. I figured that since it conforms more or less to the shape of the tire all the way to the bead, and that I removed any sharp corners, it won't damage the tube.
Is there any reason why this is a bad idea, or is it a fine jerry-rig for the next couple days in which I'll do probably do about 80 minutes of riding?
Please let me know your thoughts. Pictures are attached. Thanks!
