Tire Check
Tires should be inspected closely during the first 3000 to 10,000 miles (5000 to 16 000 km) for abnormal wear.
Maintain the proper pressures for carried loads, per the tire manufacturers' recommendations, or the tire pressure label on the driver's door.
Truck alignment must be done at the initial maintenance. Refer to
of the Western Star 47X and 49X Workshop Manual for instructions on the wheel alignment.
Do not continue to drive the vehicle if tires develop any of the following:
-
blisters;
-
cuts or punctures that reach to the cord;
-
a nail, screw, rock, or other puncturing object;
-
flat spots or irregular wear;
-
tread worn to a minimum depth;
-
inability to maintain proper tire pressure.
