2014 Lancia Thema tire size

It is recommended you contact your
authorized tire dealer or original
equipment dealer with any questions
you may have on tire specifications or
capability. Failure to use equivalent
replacement tires may adversely af-
fect the safety, handling, and ride of
your vehicle.
WARNING!
Do not use a tire, wheel size orrating other than that specified
for your vehicle. Some combina-
tions of unapproved tires and
wheels may change suspension
dimensions and performance
characteristics, resulting in
changes to steering, handling,
and braking of your vehicle. This
can cause unpredictable handling
and stress to steering and suspen-
sion components. You could lose
control and have a collision re-
sulting in serious injury or death.
Use only the tire and wheel sizes
with load ratings approved for
your vehicle.

WARNING!(Continued)
Never use a tire with a smallerload index or capacity, other than
what was originally equipped on
your vehicle. Using a tire with a
smaller load index could result in
tire overloading and failure. You
could lose control and have a col-
lision.

Failure to equip your vehicle with
tires having adequate speed capa-
bility can result in sudden tire fail-
ure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of
a different size may result in false
speedometer and odometer read-
ings.
TIRE CHAINS
(TRACTION DEVICES)
Use of traction devices require suffi-
cient tire-to-body clearance. Follow
these recommendations to guard
against damage.
Traction device must be of proper size for the tire, as recommended by
the traction device manufacturer.
Install on Rear Tires Only.
Due to limited clearance, on a 235/ 55R18 100V, use reduced size snow
chains or traction devices with a
maximum projection of 6 mm be-
yond the tire profile.
WARNING!
Using tires of different size and type
(M+S, Snow) between front and
rear axles can cause unpredictable
handling. You could lose control
and have a collision.

General Information” in “Starting
and Operating” for information on
how to properly inflate the vehicle’s
tires. The tire pressure will also in-
crease as the vehicle is driven - this is
normal and there should be no adjust-
ment for this increased pressure.
The TPMS will warn the driver of a
low tire pressure if the tire pressure
falls below the low-pressure warning
limit for any reason, including low
temperature effects and natural pres-
sure loss through the tire.
The TPMS will continue to warn the
driver of low tire pressure as long as
the condition exists, and will not turn
off until the tire pressure is at or above
the recommended cold placard pres-
sure. Once the low tire pressure warn-
ing (Tire Pressure Monitoring [TPM]
Telltale Light) illuminates, you must
increase the tire pressure to the rec-
ommended cold placard pressure in
order for the TPM Telltale Light to
turn off. The system will automati-
cally update and the TPM Telltale
Light will turn off once the system
receives the updated tire pressures.The vehicle may need to be driven for
up to 20 minutes above 24 km/h in
order for the TPMS to receive this
information.
For example, your vehicle may have a
recommended cold (parked for more
than three hours) placard pressure of
2.1 BAR. If the ambient temperature
is 20°C and the measured tire pres-
sure is 1.9 BAR, a temperature drop to
-7°C will decrease the tire pressure to
approximately 1.6 BAR. This tire
pressure is sufficiently low enough to
turn ON the TPM Telltale Light. Driv-
ing the vehicle may cause the tire
pressure to rise to approximately 1.9
BAR, but the TPM Telltale Light will
still be ON. In this situation, the TPM
Telltale Light will turn OFF only after
the tires are inflated to the vehicle’s
recommended cold placard pressure
value.CAUTION!
The TPMS has been optimized
for the original equipment tires
and wheels. TPMS pressures have
been established for the tire size
equipped on your vehicle. Unde-
sirable 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. It is recom-
mended not to use aftermarket
sealants or balance beads if your
vehicle is equipped with a TPMS,
as damage to the sensors may re-
sult. In case of use of aftermarket
tire sealants not equivalent to the
original TIREFIT sealant, please
take your vehicle to a authorized
dealer to have the sensor function
checked.
After inspecting or adjusting the tire pressure always reinstall the
valve stem cap. This will prevent
moisture and dirt from entering
the valve stem, which could dam-
age the TPMS sensor.

in your area, a high cetane “pre-
mium” diesel fuel may offer improved
cold-starting and warm-up perfor-
mance.
BIODIESEL FUEL
REQUIREMENTS
A maximum blend of 7% biodiesel
meeting the EN590 standard are also
recommended for use with your diesel
engine. See your authorized dealer for
further information regarding fuels
available in your area.
ADDING FUEL
1. Press the fuel filler door release
switch (located in the driver's door
map pocket).2. Open the fuel filler door.
3. There is no fuel filler cap. A flap-
per door inside the pipe seals the sys-
tem.
4. Insert the fuel nozzle fully into the
filler pipe – the nozzle opens and
holds the flapper door while refueling.
NOTE: Only the correct size
nozzle opens the latches allowing
the flapper door to open.
5. Fill the vehicle with fuel – when
the fuel nozzle “clicks” or shuts off the
fuel tank is full.
6. Remove the fuel nozzle and close
the fuel door.NOTE: A funnel is provided (lo-
cated in the trunk in the spare tire
area) to open the flapper door to
allow for emergency refueling with
a gas can.CAUTION!
To avoid fuel spillage and overfill-
ing, do not “top off” the fuel tank
after filling.
WARNING!
Never have any smoking materi-
als lit in or near the vehicle when
the fuel door is open or the tank is
being filled.

in its "loaded and ready for opera-
tion" condition. The recommended
way to measure GTW is to put your
fully loaded trailer on a vehicle scale.
The entire weight of the trailer must
be supported by the scale.
Gross Combination Weight Rating
(GCWR)
The GCWR is the total permissible
weight of your vehicle and trailer
when weighed in combination.
NOTE: The GCWR rating in-
cludes a 68 kg allowance for the
presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity
of the front and rear axles. Distribute
the load over the front and rear axles
evenly. Make sure that you do not
exceed either front or rear GAWR.
Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting and
Operating” for further information.WARNING!
It is important that you do not ex-
ceed the maximum front or rear
GAWR. A dangerous driving condi-
tion can result if either rating is
exceeded. You could lose control of
the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward
force exerted on the hitch ball by the
trailer. In most cases, it should not be
less than 7% or more than 10% of the
trailer load. Tongue weight must not
exceed the lesser of either the hitch
certification rating, or the trailer
tongue chassis rating. It should never
be less than 4% of the trailer load, and
not less than 25 kg. You must consider
tongue load as part of the load on your
vehicle and its GAWR.
Frontal Area
The frontal area is the maximum
height multiplied by the maximum
width of the front of a trailer. Trailer Sway Control
The trailer sway control can be a me-
chanical telescoping link that can be
installed between the hitch receiver
and the trailer tongue that typically
provides adjustable friction associ-
ated with the telescoping motion to
dampen any unwanted trailer sway-
ing motions while traveling.
If equipped, the electronic Trailer
Sway Control (TSC) recognizes a
swaying trailer and automatically ap-
plies individual wheel brakes and/or
reduces engine power to attempt to
eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the
trailer tongue weight, just as if it were
luggage located at a hitch ball or some
other connecting point of the vehicle.
These kinds of hitches are the most
popular on the market today and they
are commonly used to tow small and
medium sized trailers.

WHEEL AND TIRE
TORQUE
SPECIFICATIONS
Proper lug nut/bolt torque is very im-
portant 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 prop-
erly calibrated torque wrench.
TORQUE SPECIFICATIONS
Lug Nut/Bolt
Torque **Lug

**Use only LANCIA recommended
lug nuts/bolts and clean or remove
any dirt or oil before tightening.
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.
After 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 ve-
hicle 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 in-
jury.
TIREFIT KIT (for
versions/markets, where
provided)
Small punctures up to 6 mm in the tire
tread can be sealed with TIREFIT.
Foreign objects (e.g., screws or nails)
should not be removed from the tire.
TIREFIT can be used in outside tem-
peratures down to approximately
-20°C.
This kit will provide a temporary tire
seal, allowing you to drive your ve-
hicle up to 160 km with a maximum
speed of 88 km/h.
