Preventive Maintenance
Wheel and Tire Replacement
WARNING! The Anti-Lock Brake System (ABS) is
calibrated for the specific tire revolutions per
mile. Use of a tire and/or wheel size different
from that originally installed on your vehicle may
cause the ABS system to not function during a
hard braking event. This could cause an accident
or serious personal injury. Consult with your
Peterbilt dealer before using a different tire and/
or wheel size than was originally installed on
your vehicle.
Tires and Wheels
CAUTION: No indication will be given via the
dashboard warning lights or buzzer if tires of the
wrong size are installed on your vehicle. See the
warning above for consequences of tires of the
wrong size.
