As long as we are talking tires, I will also say this :
Unless the tire in question is a Firestone R4S or SteelTex, or a GoodYear Wrangler HT, in 99% of the "blow-out" cases, it is not really a blow-out, but a run-flat situation.
How it plays out, ESPECIALLY on a trailer or the rear of a DRW, is a tire will get punctured, causing a slow leak.
It goes un-noticed and keeps losing air-pressure, until the side-walls are in contact with the road; the driver just goes faster.
Heat builds up; then, KER-BOOOOMMMMMM!!!!!!!!!, that sorry brand _____ tire just blew out and nearly caused me to wreck.
Maybe I pay more attention than most, but just start noticing peoples tires on all kinds of vehicles; you will be amazed to see how many $50,000 vehicles are driving around on half-flat tires; you are meeting these people at seventy-miles-per-hour, while they are talking on their cell-phone, eating a burger, playing with the GPS, and talking to ON-STAR.
Just a walk across the Walmart parking-lot will yield more than 2/3s of the vehicles with at least one tire that is 15-PSI or more low.
The driver will come out, blabbing on a cell-phone and smoking, yank a youngen's arm about half off and toss him into the backseat, strap a baby into the car-seat, pick his pacifier off the ground and stick it back in his mouth, glance around to see that no one that cares is watching and then toss two rolled-up dirty diapers into the bed of the PowerStroke sitting close by, slam the door, back out in front of someone, squeek the tires, pull right out in front of a 4700-gallon tri-axle milk-truck, and floor-board it, never missing a word on the phone, and head to the house at seventy-miles-per-hour, never noticing that the left-front tire is running on the sidewalls; this scenario plays out dozens of times each day in every town in America.
