bisticles posted:A fully loaded tire busting loose will fuuuuuck you up. No kidding. One of the rear tires exploded on a trailer a few car lengths in front of me not long ago. Sounded like a shotgun and started spewing out giant hunks of rubber as it tore itself to pieces. Scared the poo poo out of me. The truck just kept on merrily bombing on down the road too. Never even slowed down.

People have been killed by large equipment tyres bursting. Those cages in tyre workshops are there for a reason.

Didn't Mythbusters show that if a tire was to catastrophically fail in the right way it could basically rip someone's head off?

I think that was more to do with a steel radial belt coming off a truck at highway speed and hitting someone in an open top car/motorcycle. Some of the more serious levels of tire related doom are aircraft tires.

As expensive as hydraulic oil is nowadays, when I inevitably pop hoses on my tractor or FEL I just start tossing 20 dollar bills on the ground limping the fucker back to the garage. I used to work as a garbageman for the summers when I was in high school. I'm sitting on the back of the truck going down the street one day when one of the hydraulic cylinders for the compactor decides to let go. All over me. The hose didn't come loose, the cylinder actually split open. It *felt* expensive. And warm. And not all that pleasant.

Yeah, I remember a friend who worked on a carrier showing me the aftermath of putting some godawful high PSI into an aircraft tire. You'd think they'd make the valve incompatible after that...

Split rims on aircraft are hilariously dangerous. Here's a randomly googled accident report. http://www.ntsb.gov/aviationquery/brief2.aspx?ev_id=20001206X01353&ntsbno=MIA94LA149&akey=1 The Beech BE-65 has a pretty small nose wheel as far as airplanes in general go, yet a piece of it was enough to slice someone's leg off.

No picture, but today i had a 2002 jeep wrangler throwing codes for engine staying cold too long. Pulled out the T-stat, drat thing had blown apart on the back side. Pretty cool to see. Tire chat: The CC i took auto classes at had something like a 30ft celing. There was a big rubber mark above the tire mounting machine. Some sod had done ~something~ wrong, probably overinflating the tire, and it blew off and hit the ceiling hard enough to leave the mark. Thats why on the side of the machines theres the stick man diagram of a guy getting his poo poo blown up when leaning over the wheel assembly.

Remember, never set your tire pressure regulator higher than 600psi! This is a rather tame informational poster, but navy's got some gruesome-rear end safety posters with all sorts of horrible injuries plastered up just about everywhere.

Here's an idea of what a catastrophic truck tire failure could do. The split rims are the worst, but a sidewall failure can happen on any style of wheel, and are loving terrifying to think about. Instant deafness at best, decapitation at worst. https://www.youtube.com/watch?v=dKlJJqHFfoQ

I still do a lot of tire work but i'm old and cautious now. I'm lucky to be all in one piece. When i was young and dumb I always took that don't inflate past 40psi to seat the bead warning as a suggestion. To think of the times i had over 100psi to get a stubborn low profile tire to seat. I always put the air ram down in the center of the wheel to help the clamps but i wouldn't think of doing that nowadays. I keep breaking them down and lubing the wheel and bead, i will max the machine though which is 50-55lbs to get them to seat.

I'm afraid to check the pressure on my piddly C load range truck tires now And I understand why the nurses in my family refuse to touch the tire pressure, even when it's obvious that they are too low.

Highspeed bit of tire tread launcher test here: https://www.youtube.com/watch?v=Vqw4ZooBzLw&t=311s They tested through a side window and didn't test a windshield at all, but I think that even a windshield could not hold up to that amount of force in one spot.

I have something topical! Not necessarily horrible, but as I was inflating a tire on my car, the valve stem popped out. The rubber part is still in the wheel, but the brass bit that the pump attaches to is on the ground.

That Mythbusters ended up being one of those that they had to really reach to make happen. They basically made a big pitching machine out of that truck and fired a chunk of retread out of it. Mythbusters aside, I sure as poo poo do not want to be around any exploding tires. On the topic of shredded tires, I've been seeing a shitload of retreads on the shoulder and often in the middle of the goddamn road. One of them is responsible for violently bifurcating my air dam. Is this just a local PA phenomenon or are dangerously lovely re manufactured tires becoming more common?

I see the carcass of at least 3 or 4 tires on the road on my ~20 mile commute every day so it would appear they're becoming more common.

Nathan Explosion posted:are dangerously lovely re manufactured tires becoming more common? Yes, in the sense that everyone continues to pinch pennies hard and harder. One way shipping companies probably cope is to run tires for longer. Road maintenance budgets are similarly shafted and no doubt contribute to this problem from the opposite direction, degrading tires faster.

Are those retreads along the roads, though? I was under the impression most were regular truck tires that became shredded due to negligence and apathy and unnoticed because the other tire was supporting the weight of the truck.

One of them is responsible for violently bifurcating my air dam. Is this just a local PA phenomenon or are dangerously lovely re manufactured tires becoming more common? This is seasonal, too. Overworked / underinflated tires often fail due to heat buildup, and when it's already hot as hell out that happens sooner and more often.

Most of the remains I see on the road have belts sticking out of them so they aren't retreads that came off.

Landerig posted:Awesome! Here, have some diesel runaway: I apologize if this is a stupid question, as I'm not very engine savvy. But in the case of a runaway, for that duration before the engine takes a huge poo poo, if you were to keep driving it would you get basically the same effect as NO2 since the oil being pulled in and burned adds to the "fuel" mixture? Basically, would you get ridiculous speed and performance for the brief duration before the engine exploded?

Nah, it would probably be less than giving it full throttle, as the air/fuel isn't controlled. That truck is in neutral/disconnected though, so it's not really fighting against much and doesn't give a gently caress about the rev limit. However it could go above the rev limit.

MadScientistWorking posted:No. They didn't really reach at all for that one because all they did was measure how fast the tread was speeding out when it did actually fail. The problem being that it was being flung out in every which direction except the location of where the dummy was. At that point you know you can get a tire to fail and shoot off at 40 MPH now how deadly is it. I only meant that they had to set it up so the tread fired directly at the dummy head. After all, the myth was that an exploding tire killed a guy. They didn't have much luck with just sitting the dummy next to the running truck and blowing the spinning tire up. Even so, having one explode next to you on the road wouldn't be fun at all.
