tirealert.com in Florida has been doing tires for forever, I think at least 20 years if not more. They put in a new tube. The club I race with does a "team order" once or twice a year. So far my flats have been on totally worn tires so I haven't participated but it's well worth it, especially for those really annoying flats that kill a tire 50 meters into its life (which is the worst for me, literally did not get from the car to registration on a brand new tire).

For a tire to get fixed the tread should be pretty good, there should be no cracks, and the casing needs to be good (no bulges indicating a cut casing thread).
