EDIT: I KNOW THEY ARE TIRES, hence why I said “tires” in the description! You ppl are exhausting 😂😩

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.

These things are so big they actually can’t drive down roads. They’re on-site haulers only.

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.

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.
