No idea about where to find tubes, but try some of the following
- Get all gunk/rubber dust out of the tire (take it off completely)
- Make sure there are no thorns left on theinsideof the tire
- Tape up the nicks in the rim, possibly with some extra old tube pieces
- Coat the tube and tire inside with talcum aka baby powder (helps to run cooler)
- When fixing old patches, scrape the old ones and the vulcanizingagent off completely before putting on a new one
- Try to find better patches (other travelers?)
- Run the right tire pressure (too low = too hot = patches fall off)
- Make sure tube is clean, and you wait until glue is completely dry before applying new patches
- Dont tighten the valve stem nut down onto the rim, but rather against the valve cap. That way your valve is less likely to be torn out when you have a flat. Check the valve regularly, if it starts to lean, you need to air up and or straighten things out
Good luck!
