Re: Flat Tires and Land Mines
We have lots of thorns here in AZ too. I use old innertubes as liners, I just cut the stems out. So far over 4,000 miles and only three flats.
If you really want to go radical, try using a old tire and cut the sidewalls out and used the tread as a liner. I have not done it on my motorized bicycle but as a kid thats how I did all my BMX tires.
