Swapped these onto my commuter bike after pinching tubes twice in a month, and the thicker walls have held up through potholes and gravel without a single flat. Air pressure still feels solid a week later too.

Swapped these in after my last tube kept pinching on rocky descents, and the thicker wall is the real difference. Held pressure for a solid week without topping off, which never happened before.

Held pressure way better than the standard tube I had before — checked it after a week sitting and it barely dropped. Only gripe is they're a bit heavier, but I'll take that trade for fewer pinch flats.
