Don't buy those tyres lol. Plenty of other tyres on the market.
32 psi won't do that damage so that's a load of shit. if you had 10psi then yeah it's plausible then.
I had a flat (twice) on one tyre, drove around for a few (10) km, pumped them up, kept driving. Bigger sidewall than yours but no damage, they were cheap Nankangs as well.
