I had three flats in one day in 2014. That was when I stopped using GP4000 tires and stopped riding my road bike until I got some Gatorskins. It has not had a single flat since. That frame will only fit 23s or narrower.
I had one flat on a rear tire on my touring bike in 2015. The tire is a Marathon Supreme 26x1.6. I believe a piece of glass cut the rear tire and punctured the tube. Tire was repaired with Shoe Goo and has gone another 1000+ miles.
I don't ride as much as many here, perhaps 2,000 miles since 2015 but I might be underestimating.
