00:00You think tires are just rubber, but in mining operations this one costs enough to buy a Porsche.
00:04For tons, for meters tall, standing beside it you only reach its waist.
00:08Every day it hauls dozens of tons of mining truck across crushed rock,
00:11not smooth road but razor sharp stones underneath,
00:13constantly being hammered rather than just compressed.
00:15So when a tire this size fails, how do you change it?
00:18First step isn't removal, it's stabilizing the entire vehicle.
00:22Dozens of tons lifted exactly 15 centimeters,
00:24too high won't work, too low won't work either.
00:27Next comes the most dangerous part, deflation.
00:30The air pressure inside these tires is terrifyingly high.
00:32Release it suddenly and the force can flip equipment over.
00:35So it releases slowly, little by little, until completely flat,
00:38confirmed safe before disassembly begins.
00:41Bolts thicker than your arm, tools the size of small machines,
00:43old tire lifted away, new tire brought in.
00:46Can't just buy any replacement, dimensions must match exactly,
00:49even slightly off won't work.
00:51Transportation requires special securing,
00:52one shake on the road and the tire could be damaged before installation.
00:56Mounted and locked, slowly inflated, workers standing far back watching carefully,
00:59confirming no bulging, no misalignment.
01:02Only when the truck settles back to ground does it truly go back to work.
01:05In mining operations there's no room for error,
01:07one tire failure doesn't just stop one vehicle.
01:09It stops or from moving, machines sitting burning money.
01:12It stops, the entire mine stops.
01:15That's why it costs what it costs.
01:16you'll see if it stops,
01:17a little bit two losing to fire frankly.
