It's best just to prevent the blowout in the first place, monitor closely, and take it like a man if it does happen to you.
Course I've never been one to want the (government--- shhhh!) to seal me in a rubber cubicle either.
The prime causes of blowouts are improper inflation or overloading.
Both easily preventable.
Don't overload. determine your proper air pressure and stick to it. Actually physically inspect your tires every once in a while (this does require getting down in the mud and crawling under your motorhome.)
Do as much as is reasonable prevention in your opinion.
You still cannot prevent everyone, it will happen someday.
