Hello,
are the folding tyre sidewalls weaker than sidewalls on wire bead tyres?

Sidewall blowing up under heavy load?
Iirc I read tyres are tested to 2x maximum pressure listed on the tin without blowing, so I would have thought if a tyre hasn't been over-inflated, over-heated, damaged, etc. and is installed on an appropriate sized modern rim an increasingly heavy load is going to cause pinch flat first, since the increase in pressure up to that point must* be relatively modest and still be within the safety margin.
* all else being equal halving the volume is required to double the pressure
Nope - but you can get folders with sturdier sidewalls than other folders if you are at all worried.

How do I know which folders have sturdier sidewalls?
I've read this 3 times and can't really understand. Would you mind rephrasing or expanding a bit? Thanks!
Imho the way to handle heavy load is to pick a tyre that a) is larger, or failing that b) can take higher pressure and pump it up to such pressure.
Regarding the tyre that blew up, I just had this realisation. I was using a 47 mm (1.85inch) wide tyre while the rim was too narrow: 22 mm. First I got pinch flats and then the sidewall ripped. Does this make sense?
