Had an offside midlift go on M1 s/b after J13 in an old ERF. It blew the mudguard over to the other side lol. Lost about 45 mins while somebody ran a unit down to me and we swapped units on the hard shoulder.
Another colleague of mine had a midlift go on a DAF CF, and it obliterated the battery. He was overtaking at the time and had to get over to the hard shoulder.
I always fear a front blowing, especially as I’ve known of drivers who have died as a result of their truck going over.
I had a middle tyre go on a low loader trailer with a out of gauge load on the passenger side in France while a RHD unit, pulled in to the side then thought that with the traffic whizzing by at speed only a couple of feet away bollux to changing the wheel here and took off to find somewhere safer to change it. Only 25cm overhang each side but by Christ don’t that make it difficult with a bloody great long heavy thing to extend the wheel nut thingy. 
First blowout for me was when inflating a rear tyre on an 8.5 meter trailer. Only four wheels, trailer weighed 3.5 tons, 14" tyre running at 85 psi. A piece of the sidewall the size of a 50p piece came whizzing past my face as I was looking at the pressure gauge and the bang left me with tinnitus for a couple of days.
Second was towing the same trailer anti clockwise on the M25 near South Mimms, tyre went with a whimper, couldn’t feel it, but could hear a funny metallic sound that was getting louder. Rim was well battered. Bit of a narrow hard shoulder, not much fun changing that in fading light with artics a couple of feet away (o/s tyre)…
