somebody who skids a lot will run through a gatorskin in no time. took my room mate 2 weeks when he got his. It was almost all skidding for fun though, almost never necessity. The soma everwear is where it is at for the skid tire. And if you don't mind the extra rolling resistance, they make a 26 that will probably last even longer than the 23.
If you want to get them cheapest buy here. And spend at least $75 and shiping is only $5. I.E. buy 3 tires at a time cause then you get the cheap shipping and a 5% quantity dicount.
