wheel size Ram 1500 2014 Get to Know Guide 

Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS low EVIC display.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue each time the vehicle is restarted as long as
the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.
NOTE:
Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air
temperature change. Keep this in mind when checking tire pressure inside a garage,
especially in the Winter. Example: If garage temperature is 68°F (20°C) and the
outside temperature is 32°F (0°C), then the cold tire inflation pressure should be
increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.

Hub Caps/Wheel Covers
• The hub caps must be removed before raising the vehicle off the ground.
• For single rear-wheel (SRW) models, use the blade on the end of the lug wrenchto pry the hub cap off. Insert the blade end into the pry-off notch and carefully pop
off the hub cap with a back-and-forth motion.
• On models with dual rear wheels (DRW), you must first remove the hub caps. The jack handle driver has a hook at one end that will fit in the pry off notch of the rear
hub caps. Position the hook and pull out on the ratchet firmly. The hub cap should
pop off. The wheel skins can now be removed. For the front hub cap use the blade
on the end of the lug wrench to pry the caps off. The wheel skin can now be
removed.
• You must use the flat end of the lug wrench to pry off the wheel skins. Insert the flat tip completely and using a back-and-forth motion, loosen the wheel skin.
Repeat this procedure around the tire until the skin pops off.
• Replace the wheel skins first using a rubber mallet. When replacing the hub caps, tilt the cap retainer over the lug nut bolt circle and strike the high side down with
a rubber mallet. Be sure that the hub caps and wheel skins are firmly seated
around the wheel.
Wheel Nuts
All wheel nuts should be tightened occasionally to eliminate the possibility of wheel
studs being sheared or the bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles/kilometers of operation to
allow the wheel nuts to become properly set. All wheel nuts should first be firmly
seated against the wheel. The wheel nuts should then be tightened to recommended
torque. Tighten the wheel nuts to final torque in increments. Progress around the bolt
circle, tightening the wheel nut opposite to the wheel nut just previously tightened
until final torque is achieved. Recommended torques are shown in the following
chart.
