I used to have "tyre scrapers", loops of wire attached to the front and rear forks that skimmed the tyre. The idea was that they'd knock off any slivers of glass or thorns you picked up before they got driven into the tube. Of course, it wouldn't help if you ran over a tack or the like, but it would if it's something that gets caught in the tread and doesn't actually penetrate till you've done a few revolutions.
