3. Tire tread design, whether traction lug or highway rib tread, makes little difference in tire mileage. The other wear
factors far overshadow the minor difference between rubber pads and voids of traction lug and rib tread design. Traction
lug tread design was selected for the CCE Dumper because it does provide more steer-ability over off-road terrain than
does a rib tread. The rib tread may be better for those users traveling predominately on pavement who are willing to
accept the poor steering response when off-road conditions are encountered.
4. The following operational points are offered to users to assist in getting the best possible front tire mileage:
_____ Accurately check the trucks front end alignment; check at six month intervals.
_____ Be very accurate in setting the front end alignment; follow manual; adjustments are critical and drastically affect
_____ Maintain correct tire pressures for your loads and your operations; don't bleed air from the front tires to obtain a
_____ Keep the payload in the dump body level front to rear; maneuver slowly at loading and dumping sites; maintain
haul roads in good repair between these sites.
_____ Turn the front wheels only when the truck is moving; don't turn the steering wheel when stopped; in
maneuvering, rock the truck back and forth when steering.
_____ Keep the interaxle differential of the rear tandem UNLOCKED; Before going into soft terrain, stop and lock this
differential and, as soon as possible, unlock it again.
