I had these same tires on my urban bike for 3 years, with zero flats and little wear showing (from the pattern engraved into the surface).
If the bike hadn't been stolen, I probably could've ridden on those tires another 5-7 years (guessing).
I'm sure these new ones will wear as well. I bike 15-20 miles a week, in a fairly urban area with some thorns and debris on the roads.
The surface of the tires looks fairly smooth, but they felt normal when gripping the road.
Just passed 5000 miles with a set of Gatorskins. Got a slight flat spot at about 2700 miles, so I flipped back to front. Had one flat so far, a steel belt shard after a Houston rain. I weigh about 205. My training rides are 40 miles, just came in from a 50 miles ride with club from bike shop. I inflate to 90 psi on front, 100 psi rear wheel. I'm sure I could go at least another 1500 miles on these, but a couple of months ago I bought some Four Season on half price sale. I know Gatorskins are a little heavier, a little stiffer, but they are exactly what I wanted.
I have no issues with this tire. They track well on all road surface types and grip the road well. Earlier this year I was caught in a rain storm (two inches in one hour) they held their grip on the road until I could find shelter.
I ran these for several thousands miles last year in the 32mm size, for training rides, commuting, gravel, and a two week loaded tour. No issues whatsoever, and not a single flat, especially remarkable given that i'm a 200 pound rider. Highly recommended.
I have over 3,000 miles on my last set of Gatorskins and as the wear dimples are almost gone, it was time to order another pair. First set of road tires that I have not experience any flats with where others have failed. I think they provide a good ride quality (though no the best) and are reasonably light weight (though not the lightest). However, as I don't race I value a trouble free ride where I may be 20 to 30 miles away from my starting point more than a few grams.
I have used these tires for the last couple of years with good results. Until now. My last set had about 2k miles on them and were starting to show wear so I changed them. Got a flat the next week, I don't know what I hit but it put a gash at the top of the sidewall. So I changed that tire after a week. Two weeks after I changed tires, I got another puncture, this one right through the center of the tire. I am no longer using this tire.
Have started using gator skins about 7 years ago and never looked back. Since using them on San Francisco and Bay Area roads they have weathered the street debris and other road issues better than most other tires. It's important to use good inner tubes because the cheep inner tubes fail long before the tires need to be replaced. Buy again? You bet!
I am not a pro, but these tires seem to be very resilient and great riding tires. They are somewhat difficult for an amateur to install, but he many videos on the subject will allow you to finish. They are much quieter than my previous OEM tires.
