These assholes have no idea how close they came to losing their faces after it actually mounted:

Don't try this at home until after at least 6 beers.

Lol... good stuff. That first clip must be from Norway cuz I hear some guy cussing in Norwegian. In the 2nd clip it looks like the tire is just about to blow.

Yeah, saw that trick done on the Top Gear "Polar Special" by one of their support crew when they fubared a rim on the ice. Think their support crew where Norwegian too....

On another note, a mate who drives one of those huge trucks used in the open cuts, tells me that a blow out on one of those has the force equal to 2 grenades. If it blows on top, the driver is toast. Or so he said.

I'm not too sure about that. Luckily, anyone that has tires like that is very unlikely to find out. For rock-crawling, the psi is reduced substantially from what is recommended for "normal" driving conditions; sometimes as low as 3 psi or so.

This makes the footprint of the tire larger and increases grip. Mudding will require more psi, but still no more than about half of what is normal. And even normal operation on paved roads, these tires shouldnt be pressurized to anything higher than 32 psi or so. Paved road operated isn't advised on super-large tires since they wear so freakin fast and are so expensive. Plus, they handle like ass and will literally pull you INTO a puddle of water instead of standard tires that repel water.

Ask me how I know and I'll show you the pictures of my crumpled Toyota 4x4 I wrecked in '97 . I had 33" BF Goodwrench MTs and a 4" suspension lift. Grabbed a large puddle while I wasn't paying 100% attention to the road and the next thing I knew I was kissing the windshield rather abruptly as the truck was toppling over.

I had to go looking.. my interest ws piqued
The tyres run at 100 psi.
These things are modded to haul around 400+ tons here in the Queensland open cuts. A tyre costs $AU70k

Another interesting thing he told me was that hitting the brakes, even fully loaded, will put you through the 'screen. They come with disc brakes, emergency hand brake & something called a 'retarder' which is what stops you real quick.

Those are definitely the wrong kind of tires. The link you posted was for a commercial mining truck.

The tires in those videos are off-road, mud-terrain tires.

I personally run 33" BFG mud terrains because I don't do mudding for fun anymore. I like to have them because I do drive places where I have to engage the 4wd fairly often. Plus, they look gooooood.

I also like TSL Thornbirds but they wear down REALLY fast on pavement and handle like complete ass. But they look great:

Belay my last, you were actually talking about one of those big bastards. Yeah, at 100psi, you're going to lose your face if it decides to burst.

I was just talking about standard mud-terrains.
