2014 Ram 2500 tire size

SYSTEMmessage will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles With Full Size Spare
1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS. 2. If you install the full size spare in place of a road tire
that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound and the “Tire Pressure Monitoring Telltale
Light” will turn ON. In addition, the EVIC will display
a “LOW TIRE PRESSURE” message and a graphic
showing the low tire pressure value flashing or in a
different color. An Inflate to XXmessage will also be
displayed.
3. After driving the vehicle for up to 20 minutes above 15 mph (25 km/h) the “Tire Pressure Monitoring
Telltale Light” will turn OFF and the pressure value
will be updated and stop flashing or return to it’s
original color, as long as no tire pressure is below the
low-pressure warning limit in any of the four active
road tires.

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
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.

**Use only Chrysler 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.
Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.
