Either way, oxygen is the big problem. That and maybe a chemical reaction with the under seat pouch material.
Humidity does not help either.
Talc is one's friend as is a zip lock bag with silca gel pack thrown in.
Butyl. Thanks for those tips. And it's only my road tubes that fail so quickly. The larger diameter ones(lower pressure) last a long time.
