I used to use gatorskins. then I stopped working at a shop and had to start buying cheap shit again. They would last me about 3 months on the rear. I didn’t skid but once every few days, if that. A few skips in certain places in my commute, but not many. We should have a contest for the brakeless riders. Everyone has to start with a new rear tire. Whoever makes it last the longest without any threads showing wins.
In defense of gatorskins, they do ride fairly nicely, have low rolling-resistance, and mine have rejected all kinds of glass and road debris. I’ve actually had to use tweezers to pull glass out of my tires that failed to cause a flat.
Why do shops get so many used tires? Do people seriously take their bikes to a shop to get the tires changed? First time I had to swap tubes on a 700x23 I had no clue what I was doing and it only took like 12 minutes tops.
