Tires and Wheels
The CCE-IHC Dump Trucks are equipped with ML (Mining and Logging) type tires. These are not highway tires. As
explained In the Tire and Rim Yearbook' (and repeated In the Engineering Data Books at your friendly local tire dealer),
ML tires need to be treated kindly in "Intermittent Service". High heat in each ML tires shoulder is the potential problem,
so- On hot days, with a heavy, heaped payload, over 50 miles one way travel:
run in "Underdrive" or "Directdrive" aux box ranges (NOT IN "OVERDRIVE") to keep speed down.
use "Overdrlve" range for coming back empty, only.
cruise along up to 30 mph, when on paved road; tires heat-up on paved highways more than on gravel or soil
during Before-Operation-Service and only if the tires are cold and have not bean run, check your tire pressure all 10 of
'em including the inner duals. When you're satisfied that the only contacts you have with the ground, your tires, are
adequately Inflated and in-balance, within a few psi, then you're able to safely put your trust and 71,000 pounds on these
