Started back to riding this past Fall after a decade-long hiatus (it’s amazing how a diagnosis of T2 diabetes will get you off your lazy ass). The other day, I was rearranging my “emergency” kit and happened across an old box of Performance Bike-brand tubes that I had apparently stocked up on back in ‘05(ish). They’re unused and have been sitting there in their retail boxes in the garage. I don’t know that I would necessarily trust them for day-to-day use at this point (or should I?), so mostly wondering if they’re at least suitable for road-side replacements. They’re “ultralight” types, so fit great in my little Topeak “Ninja” water bottle cage pouch.

So I gues the “TL;DR” is what’s the shelf-life on tubes?

(Related: I also have some unused Vredestein tires from that time. Still good? They don’t feel brittle.)
