I had a blowout in a loaded 7.5 tonner once. Inside trye on the rear went, and I didn’t realise anything was wrong until a car came past, put his hazards on and pulled over to the hard shoulder, indicating that something was wrong. As I was only just short of a junction I drove slowly down the hard shoulder and stopped in a layby just off the motorway.
I’ve also been in the bus when tyres have blown on the back (never fit Polish tyres…) They dont half blow with a bang when they go (90 psi)

I FLIPPING WELL KNEW IT 
So I post what I do when I get a blowout last night. Gets to work at 4am this morning - FLAT TYRE ON TRAILER. 
Talk about giving fate a good kick up the backside with a size 10.
Anyway so I ended up practicing what I’d said.
Be careful if driving with a blown or badly under-inflated tyre, because it is an offence to do so.Some eagle- eyed plod will gladly book you for it.
And as already explained, a blown tyre will rip away everything else surrounding it, lights mudguards & bodywork.
It is surprising how many tyres fail through under inflation,especially twins,
few people pay attention to tyre valve extensions, the inside tyres suffer from neglect. if you suspect a flat tyre, try to get it sorted before you take the vehicle out. Waiting in the depot for a tyre fitter for an hour, is much more cost effective
than sitting on the motorway for ages,waitng for somone to run into you!
If you are prepared to get on your knees and look underneath, you will usually see a partially flat tyre, with saggy walls or uneven tread wear,which will give an indication of something wrong. Watch out for cheap remoulds,these are classic candidates to go bang
You would be amazed at the number of trucks running around with flat inside tyres, most which could be prevented by better tyre management.
Finished onsite today to find truck leaning on passenger side. Trundled off to a garage nearby and found tyre at 60psi. Luckily the garage had an air line next to the HGV pump that could take up to 100psi, so got it up to 85 before the compressor went on the blink. 
Hmm.
Anyway, got the truck home OK, no other problems, and tyre crew there to replace the tyre for me when I got in. Thank you Engineer
