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.

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

tire wear.

_____ Maintain correct tire pressures for your loads and your operations; don't bleed air from the front tires to obtain a

softer ride.

_____ 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.
