I had a blowout on whatever crappy Michelin tyres were on the road bike I hired in the Algarve.
A pickup truck inched out of an entrance to a field into my path as I was coming down a fairly steep descent.
I locked on the brakes to avoid it, skidded a bit, then there was a bang and I had a big hole in both tyre and tube.
Since I was out in the wilderness, I ended up making a tyre boot out of a banana skin, which wore out, then out of a bit of eucalyptus bark, then another bit, and limping back to civilisation.
Replaced the tyre at the first bike shop I happened upon.
The hire shop wouldn’t reimburse me for the newer, better tyre and insisted I take it off the bike when I returned it.
