2009 Ram 1500 tire size

1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the “TPM Telltale Light” will still turn ON
due to the low tire.
3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (25 km/h), the “TPM Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition key cycle, a chime will
sound and the “TPM Telltale Light” will flash on and off
for 75 seconds and then remain on solid.5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and the “TPM
Telltale Light” will turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any of the four
active road tires. The vehicle may need to be driven for
up to 20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.

included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the
driver, all passengers, options and cargo.
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 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.

To Stow The Flat Or Spare
NOTE: Vehicles equipped with aluminum wheels can-
not be stored under the vehicle because the wheel
retainer will not fit through the wheel pilot hole. Secure
the flat tire in the bed of the truck. Have the flat tire
repaired or replaced immediately.
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.
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.
Attach the wheel wrench to the extension tube. Rotate the
winch mechanism until the wheel is drawn into place
against the underside of the vehicle. Continue to rotate
until you feel the winch mechanism slip or click three or
four times. It cannot be overtightened. Push against the
tire several times to be sure it is firmly in place.
