I can't say that the Tubolitos are more puncture resistant than butyl rubber with Tannus Armour. They have been tested and shown to be about twice as puncture resistant as butyl rubber tubes. I suspect they will be more puncture prone than a tire fitted with Tannus. We shall see just how much over time. As of now I am so glad to be rid of them, going faster and further, that it looks to be a trade off I prefer. Real results over time may change that.What pressure do you keep the tubolito's at? I can be convinced to change out the Tannus inserts if the tubes really are more resistant to punctures. I'd rather hear it from you than the Tubo folks.
