I toured in Thailand with those tires for three months and only had one flat tire and it was by my own fault:I biked trought a really bad area full of boken glass with my full load.I didn’t have the flat right away but some time later.When I fixed the tire I realized that I had the flat because there where a cut.Thinking back I remenber biking in that area full of broken glass.I learned a lesson:those tires are excellent but you still have to be smart enough not to abuse them.Mario Preston.
