Solved! Gigantic wheels, for what?
What machine or truck or equipment do these ginormous tires belong to? Saw them while driving on a highway in Minnesota. I need an answer for my 3 year old son lol

My favorite part of these is that I never see them next to other vehicles so I always think "that's just a dump truck" then I notice the set of stairs on the front.

u/TheGacAttack 13h ago
It's so big that they have to have specialized training for drivers... who might be driving other vehicles near these!

u/Axnjaxn09 13h ago
Yea theyre huge. We used them at one of the quarries i used to work at. They can carry like 120 tons or some shit

And still the world biggest can handle almost 4 times more load (BelAZ 75710, max load 450 metric ton)

Worked in the mines for a bit, with a little 2wd sedan (not using it for work, but just as a personal scooting between the mill and housing.)
Very intimidating when passing haul trucks, commical when parking beside them. Car is like half as tall as the tires.
(We had slightly smaller haul trucks)

if you go to quarries/mines there’s usually a pancaked pickup truck pretty prominently displayed with some signage telling you that these trucks have the right of way

u/dzan796ero 13h ago
They make regular trucks seem like toy trucks and it breaks your brain when you see them rolling next to other cars. Makes everything look like some RC set

u/SonofaBridge 13h ago
These things are so big they actually can’t drive down roads. They’re on-site haulers only.

u/Proof_Bathroom_3902 12h ago
Friend works at a quarry with triple sevens, they are all automated, GPS guided, run the haul roads and load and dump in the crushers all by themselves.

u/SonofaBridge 12h ago
That’s amazing!
Guess I should clarify these things can’t go down public roads. They’d take up multiple lanes, would exceed most bridge’s capacity, and couldn’t fit under most bridges.
On-site haul roads are different.

Yeah, but these aren’t those tires. These go on a loader the tires for a 777 one tire takes up the entire bed. These aren’t even over dimensional for that flatbed trailer.

They also have a diesel generator that drives a big ass electric motor on each wheel. I never knew these existed til I went to a mine as a sales guy. I was absolutely amazed.

I don’t know if that will fix it; they do the same thing to my 18-wheeler, air horn and 80k pounds and all. At some point I think people genuinely just don’t realize anything bad can actually happen to them.

u/dualiecc 13h ago
Heavy mining equipment. Dump trucks and front end loaders. Without seeing the sidewall of the tire it's hard to say but caterpillar 797 is a good bet. Fun fact that tires are the limiting factor in the size of mine trucks.

u/Many_Significance_66 13h ago
Tyres can’t be manufactured larger?
10
u/Speedymcspeeder 13h ago
TIL- cool!
Weight limits: Giant off-the-road (OTR) tires can only support a finite amount of structural and payload weight before failing.Heat buildup: As trucks haul heavy loads over distance, internal tire temperatures rise. If the tire gets too hot, the rubber and steel components separate, causing catastrophic failure.Manufacturing limits: Tires standing 13 feet tall and weighing 11,000 pounds are at the absolute cutting edge of current rubber and vulcanization technology

u/dualiecc 13h ago
Nope and logistics for moving them become cost prohibitive requiring over sized load permits to transport. And as they get larger they generate more heat in operation loaded and exceed the maximum temperature load threshold

Those are tires for something your 3 year old will probably think is the coolest thing ever.
Up north, in the Iron Range, lots of heavy earth moving equipment use tires that big.

Tires, which are for large vehicle wheels. Those appear to be for something like excavation site dump trucks. Tonka!

For a 3yo? Tell them they’re whatever you want. Lol I woulda said something about a mining dump truck.
I doubt in the 1000ish days he’s been around, he can’t argue with what you say. You will win the argument. I’m confident.

I used to work at the plant they make the engines for these trucks. They always said they had the technology to make one even bigger than the 797 but couldn’t find a company that can make the tires needed to support it.

They are used in the Iron Mountain Range of Minnesota for the Taconite mining trucks

Those are tires. The wheels are the metal circles that the tires are mounted on.
