A UST tire is a normal tire without a tube, in the sense if it gets a puncture it's going to go flat. The product I mentioned was
Stan's No Tubes It's a sealant that goes in the UST tire to seal it as a puncture happens, the tire NEVER goes flat.
I've pulled thorns and even a thumb tack out of my tire. It works just as well with non-UST tires, My first set was the tires that came on my bike, I used the Stan's conversion and rode them smooth.
When I replaced them with UST tires I ran my hand inside the old tire and no exaggeration 25 thorns in the back easy.
Never had a flat and you can run lower tire pressures and not have to worry about pinch flats. I was running 25psi upstate NY, rocks roots, big drops--very ugly, ripped a brake line off the rear caliper, but never flatted.
I just went to Stan's site and noticed they have a 700c conversion, that will be on my X-mas list this year.
The biggest problem with goat heads, are that you generally don't just get one or two in your tire, usually it's 20 or 30 of them, I used to use that stans stuff in place of slime but it didn't work any better and costs more so I went back to the slime.
