Old tire bead incredibly sharp. Cut my finger fairly deep.

I had a very cheap 4 year-old set of tires sitting around, & not being ridden. They had come with a Walmart bike & after a couple of flats I upgraded to a set of Continentals, & no flats since!

But today, as I was sorting through those old tires I sliced my finger pretty badly on the inside edge (by the bead), which had gotten hard over the years & thus very sharp.

Is this common with bike tires generally as they sit unused, or is it just something that happens to cheap-o tires?

I threw that set out, but I'm wondering if I need to be careful with better quality spare tires I may have laying around in the future. Also, I'm just a little curious.

Thanks in advance for sharing your experiences.

Incentive is to buy less cheap tires?

I haven't cut myself, but have noticed that phenomenon on older tires. I don't think it's limited to cheap tires.

I expect that what cut you was a wire strand that separated from the wire bead and poked through the rubber casing. The rubber had probably age hardened and gotten brittle.

Or to build up your calluses.

I've slashed fingers many times from old dry tire beads. Occupational hazard. Krazy Glue works great for closing them up.

It wasn't the metal wire actually. I did suspect that, but when I checked more closely, the rubber was sharp all around, no exposed wire, & I could actually break off the sharp rubber edge...

I'll be more careful &/or put on some gloves before handling old tires in the future.
Thanks!

With practice you'll learn to recognize which tires are likely to slice you. Dues.
