Using Old Tubes

[dmc]

I've been running through tubes. I have low grade tires on a low grade bike.

Today I installed Mr. Tuffys tire liners.

I have 3-5 tubes that have extremely small puncture wounds on them. THESE ARE GOOD TUBES!!! Can I like patch them and fill them up with a bunch of slime and get my money the ghetto way? Some of these tubes have the smallest of puncture wounds. I would feel so much better if I could invest 10 bucks and have them as backups in my seat bag.

Whats up? Each tire in my mind's eye is a five dollar bill. I havent tossed them because I believe they are still valuable. Am I crazy? Help me save moneh!
