Inscription. Tires displayed here were for the 170 and 240 ton capacity production mine trucks used at Hibbing Taconite Company immediately to the north of this view site.

The tires for the 170-ton trucks are mounted on wheels that are 4.25 feet in diameter and with a tire diameter of 10.5 feet. It takes only 162 revolutions to cover the distance of a mile.

The 240 ton truck tires cost more than $20,000 each and a complete set of six would be more than $118,000 total. Even though the tires are 50 ply and the tread depth greater than 3 inches the sharp taconite fragments can puncture them.

At a total height of nearly 12 feet the 240 ton truck tires are mounted on 4.75 foot diameter wheels for use on 240 Ton capacity haulage trucks. The maximum width of these tires is 40 inches.
