Do not install a wheel cover or attempt to mount a conven-
tional tire on the collapsible spare wheel, since the wheel is
designed specifically for the collapsible spare tire.
Full Size Spare — If Equipped
The full size spare is for temporary emergency use only. This
tire may look like the originally equipped tire on the front or
rear axle of your vehicle, but it is not. This spare tire may
have limited tread life. When the tread is worn to the tread
wear indicators, the temporary use full size spare tire needs
to be replaced. Since it is not the same as your original equip -
ment tire, replace (or repair) the original equipment tire and
reinstall on the vehicle at the first opportunity. Limited Use Spare — If Equipped
The limited use spare tire is for temporary emergency use
only. This tire is identified by a label located on the limited
use spare wheel. This label contains the driving limitations
for this spare. This tire may look like the original equipped
tire on the front or rear axle of your vehicle, but it is not.
Installation of this limited use spare tire affects vehicle
handling. Since it is not the same as your original equipment
tire, replace (or repair) the original equipment tire and rein
-
stall on the vehicle at the first opportunity.

Compact and Collapsible spares are for temporary
emergency use only. With these spares, do not drive

limited tread life. When the tread is worn to the tread
wear indicators, the temporary use spare tire needs to be
replaced. Be sure to follow the warnings, which apply to
your spare. Failure to do so could result in spare tire
failure and loss of vehicle control.

TECHNICAL SPECIFICATIONS 565
BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
Hydraulic Brake Assist — 2500/3500 Models Only
(Except Power Wagon)
The brake system power assist is provided by a hydro-boost
unit which shares fluid with the power steering system. You
may experience some clicking or hissing noises from the
hydro-boost system during hard braking conditions.
NOTE:
Under cold temperatures, pedal effort will be higher than
normal until the power steering fluid reaches operating
temperature.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.
