Two lanes wide, tires 13' tall, now thats a truck!!!!

Caterpillar 797 is one of the biggest mining trucks built by the company. The tires are made by Michelin at the cost of $42000. for each. 

They stand at 13.22' tall, and weigh 42,500 lbs per tire. The truck sells for 3.4 million dollars. Check the size of these trucks. 

You can really tell how large it is when it passes a tractor trailer at the guard house. Then watch them pass full size pickups on the dirt road. Picture was take at Minntac, at Mountain Iron, MN. 10-2003.
