I have a set of cyclo-cross tires I use on my bike during the Boston winters, but last year I found a 9mm gash in the tread of one of them (all the way down to the tube). Luckily, it was at the end of the winter and these tires didn't have many nubs left, so I put the tires in the corner thinking I'd replace them the following winter. Well, when winter rolled around I threw them back on the bike but I booted the gash with two layers of Tyvek from a mail envelope.
After a month, I replaced the Tyvek with a fresh two-layer boot. One layer of the original boot had pretty much worn through. They don't sweep the roads during the winter, so there's a ton of sand and gravel on the road which worked it's way into the gash to abrade the Tyvek.
Today, after another month of commuting, I switched back to normal commuting tires without any flats due to the gash. I only ride about 5mi per day, but the tires lasted another two months; nice!

How do you get Tyvek from a mail envelope? You need more pictures on this blog!
The envelope is made out of Tyvek instead of paper. You can cut it with a pair of scissors. I'll put up some pictures when I have a minute.
