Thanks, I’ll try for a refund.

Schwalbe! That’s why I’m surprised, I’ve never had issues with them.

No kidding ;)

Sorry, that was a typo! 30psi is what I meant to write.

They are rated 50psi max, but I had tried running them as low as 30psi for a cushy ride for a while. Wasn’t sure how low is too low. Maybe more of a problem because my inner rim width is only 19mm for these 50mm tires? Still within spec but on the narrow end for sure.
