Well Dave. Polish roads are clean, and we specifically have very little thorn if any. If I ever had a flat, it was only because I had installed the tube wrongly (pinched by the tyre bead) or I damaged the tube valve. If I get a flat again, I will be first to tell you
I use really good tyres but incidents happen everywhere. However, my friend Jerzy rode for an improbable distance on his Continental tyres (until they got bald) without a single flat!
