Isn't it common knowledge that the same-side second tire has very likely suffered internal damage from the shock of the sudden additional loading and that it, too, is probably shot??? (Regardless of "country of origin"/type )
Common misconception.
In your opinion...
I think a much more common misconception is that a tire on a dual axle rig is spec'd/sized for "redundancy" in case its neighbor fails. They aren't. (Unless of course the user has "upsized" and doubled the capacity of the original tire.)
The sudden, violent doubling of the load on a tire unspec'd to take such treatment will almost always do interior damage to it. I frankly would automatically replace such a tire, as in my opinion there are few things more critical to my safety than the rubber I'm rolling on. That tire should be at least demounted and its interior inspected. Best practice is to do the same with those on the opposite side of the rig as well. They've had a shock, too, though not as great.
This of course understanding that we're talking about a blowout at highway speed.
I'll post supporting links if anyone is interested in seeing them. But since they're all connected to actual tire companies, I'm sure some would dismiss them as some kind of scam/marketing ploy designed only for the purpose of selling more tires.
