inflation pressure Ram 1500 2015 Owner's Guide

the pressure values of each tire with the low tire pressure
values in a different color. An#Inflate to XX#message will
also be displayed.
Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
in a different color in the EVIC/DID graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in the#Inflate to XX#message. Once the
system receives the updated tire pressures, the system
will automatically update, the graphic display in the
EVIC/DID will return to it’s original color, and the “Tire
Pressure Monitoring Telltale Light” will turn off. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds and
then remain on solid. The system fault will also sound a
chime. In addition, the EVIC/DID will display a#SER-
VICE TPM SYSTEM#message for a minimum of five
seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.

630 STARTING AND OPERATING

Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commer-
cial scale to insure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should
then be determined separately to be sure that the load is
properly distributed over the front and rear axle. Weigh-
ing the vehicle may show that the GAWR of either the
front or rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier

Towing Requirements — Tires
•Do not attempt to tow a trailer while using a compact
spare tire.
•Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
•Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
•Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting and Operating” for the
proper inspection procedure.
•When replacing tires, refer to “Tires – General Infor-
mation” in “Starting and Operating” for proper tire
replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in an
accident.

9. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
To Stow The Flat Or Spare
NOTE: Have the flat tire repaired or replaced immedi-
ately.
WARNING!
A loose tire thrown forward in a collision or hard
stop could injure the occupants in the vehicle. Have
the deflated (flat) tire repaired or replaced immedi-
ately.
1. Turn the wheel so that the valve stem is facing the
ground and toward the rear of the vehicle for conve-
nience in checking the spare tire inflation. Slide the
wheel retainer through the center of the wheel.
