As to flats, I can tell you on my 2 bike with the Pasela TG tires i have gotten a total of 1 flat which i think was due to glass. I have not put in a lot of miles, maybe 1K on both bikes total. But before I got these tires i was getting continual flats on one of the bikes with a pair of 25mm CSI Czar which are very cheap chinese tires.

I ride on city streets and bike paths and never encounter goatheads. The problem is just misc. debris and bits of glass. I am satisfied with the tradeoff of flat protection and responsiveness/lightness with the TG tires. I am comparing them to those cheap tires that were constantly getting flats and on the other hand to a pair of Schwalbe Marathon Plus 38mm 700c on a hybrid bike that I dont like due to weight and dead feeling.

I find the TG tires to be very comfortable and nice riding.

But if i were commuting daily i might go with the Marathon instead, thinking it might be more durable. It is a tough decision and I havent tried the Marathon. It depends how risk adverse you are to flats. TG isnt a big risk but probably slightly more risk of flats than Marathon.
