Traveling south on 95 through South Carolina yesterday, came up on this.

I promise you, it's not Photoshop, that's not in my skill set.

My first view, total WTF moment.

A little closer

Catching up

Even with the truck

One big ass rock mining truck, I'd say.

So that trailer is approx 110".  Some quick eyeballing suggests the tire OD is around 12 feet.  

Mining truck is a good suggestion, but the tread pattern looks awfully street-tire-ish

I'm with Streetwiseguy, although they seems to have more tread blocks than normal.  EX:

I worked for BS/FS for ten years and they sold those things, I was at dinner once with a guy who was just back from South America and said that “bandits” would steal ten of those off a train and re-sell them to the mine. I couldn’t wrap my head around stealing ONE of them and transporting it anywhere to hold it hostage. And the cost!!!!

How many miles do you get out of a set? Or do they track it in hours or something else? How much do they cost each?

I thought of the big mining trucks, but I only know of them from photos.

I've never seen one here in the east. The tread pattern didn't look like I would expect for one of those either.

I think Chandler answered the question; that certainly seems like the most logical possibility.

2,300 ft-lb - I think that requires the Milwaukee M-240 cordless impact. cheeky

I have read that the size of mining trucks in general is limited by the size of tires. They can assemble a massive truck on site from smaller subassemblies, but the tires must be delivered from one place to another. Tire size is limited by lane width and bridge height encountered by the shipper.

I find it odd that the truck is not running banners for oversized load due to the excessive height. 

Also odd that what seems like a normal shipping container has no roof.

That's an open top container.



You can see the hooks at the top where a tarpaulin would be fastened over it.

Reading further down the spec sheet - 

Gross operating weight - 1,375,000 lb (623,700kg)

Top speed - 42 mph (68 km/h)

 

42 mph in a 688 ton truck sounds absolutely terrifying.  Mostly to anyone not inside the truck.

In the early 80's I had a project in a copper mine in central British Columbia, so I had to drive around in a large pit and cross the haul road multiple times a day. As a contractor's employee I was required to attend the mine's safety training sessions. One day they did a demo of one of the 3 axle WABCO haul trucks backing over an old pickup. I was impressed and never once attempted to cross the haul road if one was even in sight. They are so big that they appear to be lumbering along at a slow speed when they're actually doing 35-40 mph. Given that they were hauling 250T loads you always yielded the right of way. My rental 4 cylinder Fox Mustang would have been flattened down to 6 inches thick if it had been hit. The loading shovels were even bigger and more impressive.

The Michelin plant near my house builds 30,000 auto tires PER DAY. 

Its sister plant builds those big tires. Similar sized plant, but production is more like 10 tires per day.

In reply to ProDarwin :

One of my customers was the open pit mine in Northern Minnesota.  Sharp rocks were the number one cause of flats which can ruin a nearly new tire. 

To combat punctures they went to less aggressive tread and tight mesh tire chains.  What was still happening was rocks would wedge themselves  in between tread and chew until they punctured the tire.  

Maybe that less aggressive tread is designed to prevent that

You can't see it in the pictures,  but to there was an oversize load banner on the truck

I’d imagine this takes a while to do, on an old seemingly worn out tire.  Things must be pricey AF.
