I use Schwalbe Marathon Plus. Since I use my bike the same way I use my car, I require the bike tires to be as flat-resistant as my car tires. I think I have succeeded, as the bike tires have given me no flats for over 20,000 miles, but I had a flat on my car last year. The annual mileage is the same on both vehicles, so it is a good comparison.

I honestly think that most bike tires are astoundingly flat-prone. One flat per 500 miles is about what car tires were getting back in the Model T era.
