2018 Ram 2500 wheel

Sustained high temperature can cause the material of
the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance, which all pas-
senger vehicle tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the laboratory
test wheel, than the minimum required by law.
WARNING!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
STORING THE VEHICLE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to minimize
the drain on your vehicle’s battery:
• Disconnect the negative cable from battery. •
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh air
and high blower setting. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants, road
surfaces on which the vehicle is operated, extreme hot or
cold weather and other extreme conditions will have an
adverse effect on paint, metal trim, and underbody protec-
tion.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resis-
tance built into your vehicle.
584 SERVICING AND MAINTENANCE

CAUTION!
•Do not use abrasive or strong cleaning materials such
as steel wool or scouring powder that will scratch
metal and painted surfaces.
•
Use of power washers exceeding 1,200 psi (8,274 kPa)
can result in damage or removal of paint and decals.
Special Care
• If you drive on salted or dusty roads or if you drive near
the ocean, hose off the undercarriage at least once a
month.
• It is important that the drain holes in the lower edges of
the doors, rocker panels, and trunk be kept clear and
open.
• If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
• If your vehicle is damaged due to a collision or similar
cause that destroys the paint and protective coating,
have your vehicle repaired as soon as possible. The cost
of such repairs is considered the responsibility of the
owner. •
If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
• If a lot of driving is done on gravel roads, consider mud
or stone shields behind each wheel.
• Use Mopar Touch Up Paint on scratches as soon as
possible. Your authorized dealer has touch up paint to
match the color of your vehicle.Spray-On Bedliner – If Equipped
During ownership, the shine and luster of the Spray-On
Bedliner can fade from oxidation, road dirt, heavy-duty
hauling and hard water stains. Weathering and UV expo-
sure will lead to fading, dulling, and loss of gloss over
time.
To help maintain the appearance of your Spray-On Bed-
liner, the manufacturer recommends you periodically rinse
all loose dirt from your truck bed and clean your truck at
least twice per year using the Mopar Spray-On Bedliner
Conditioner available at your local authorized dealer.

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 cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

**Use only your authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening. NOTE:
Dual wheels are flat mounted, center piloted. The
lug nuts are a two-piece assembly. When the tires are being
rotated or replaced, clean these lug nuts and add two drops
of oil at the interface between the lug nut/bolt and the
washer. Do not oil wheel studs.
Two-Piece Lug Nut
594 TECHNICAL SPECIFICATIONS

Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it half-
way).
After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts fully until the vehicle has been
lowered. Failure to follow this warning may result in
personal injury.Wheel Mounting Surface
