2017 TESLA MODEL X tire pressure

Braking Systems
Model X has an anti-lock braking system
(ABS) that prevents the wheels from locking when you apply maximum brake pressure. This
improves steering control during heavy
braking in most road conditions.
During emergency braking conditions, the
ABS constantly monitors the speed of each
wheel and varies the brake pressure according to the grip available.
The alteration of brake pressure can be felt as
a pulsing sensation through the brake pedal.
This demonstrates that the ABS is operating
and is not a cause for concern. Keep
firm and
steady pressure on the brake pedal while
experiencing the pulsing.
The ABS indicator flashes briefly on
the instrument panel when you firststart Model X. If this indicator lights
up at any other time, an ABS fault
has occurred and the ABS is not
operating. Contact Tesla. The braking system remains fully operational and
is not
affected by an ABS failure.
However, braking distances may increase.
If the instrument panel displays this
indicator at any time other than
displaying
briefly when you first start
Model X, a brake system fault is
detected or the brake
fluid level is
low. Contact Tesla immediately.
Emergency Braking
In an emergency, fully press the brake pedal
and maintain
firm pressure, even on low
traction surfaces. The ABS varies the braking
pressure to each wheel according to the
amount of traction available. This prevents
wheels from locking and ensures that you stop
as safely as possible.
Warning: Do not pump the brake pedal.
Doing so interrupts operation of the ABS
and can increase braking distance.Warning: Always maintain a safe distance
from the vehicle in front of you and be
aware of hazardous driving conditions.
While the ABS can improve stopping
distance, it cannot overcome the laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of
water prevents direct contact between the tires and the road).
If Model X is equipped with Autopilot
hardware, Automatic Emergency Braking
automatically applies full braking in situations
where a collision is considered imminent (see
Automatic Emergency Braking on page 97).
Brake Wear
Model X brake pads are equipped with wear
indicators. A wear indicator is a thin metal
strip attached to the brake pad that squeals as
it rubs against the rotor when the pad wears
down. This squealing sound indicates that the
brake pads have reached the end of their service life and require replacement. To stop
the squealing, contact Tesla Service.
Warning: Neglecting to replace worn
brake pads results in damage to the
braking system and can create a braking
hazard.

Service Intervals
Regular maintenance is the key to ensuring
the continued reliability and
efficiency of your
Model X.
Maintain the correct tire pressures, and take
Model X to Tesla at the regularly scheduled
maintenance intervals of every 12 months, or
every 12,500 miles (20,000 km), whichever
comes
first. It is also important to perform the
daily and monthly checks described below.
Model X must be serviced by
Tesla-certifiedtechnicians. Damages or failures caused by
maintenance or repairs performed by non-
Tesla
certified technicians are not covered by
the warranty.
Daily Checks

Maintaining Tire Pressures
If you are not towing a trailer, keep tires
inflated to the pressures shown on the Tire
and Loading Information label, even if it differsfrom the pressure printed on the tire itself. The
Tire and Loading Information label is located
on the center door pillar and is visible when
the driver

Inspecting and Maintaining TiresRegularly inspect the tread and side walls for
any sign of distortion (bulges), cuts or wear.Warning: Do not drive Model X if a tire is
damaged, excessively worn, or inflated to
an incorrect pressure. Check tires
regularly for wear, and ensure there are
no cuts, bulges or exposure of the ply/
cord structure.
Tire Wear
Adequate tread depth is important for proper
tire performance. Tires with a tread depth less
than 4/32” (3 mm) are more likely to
hydroplane in wet conditions and should not
be used. Tires with a tread depth less than
5/32” (4 mm) do not perform well in snow and
slush and should not be used when driving in
winter conditions.
Model X is originally
fitted with tires that have
wear indicators molded into the tread pattern. When the tread has been worn down to 4/32”(3 mm), the indicators start to appear at thesurface of the tread pattern, producing the
effect of a continuous band of rubber across
the width of the tire. For optimal performance
and safety, Tesla recommends replacing tires
before the wear indicators are visible.
Tire Rotation, Balance, and Wheel Alignment
Model X tires cannot be rotated, as tires are
asymmetrical and front tires are a
differentsize from rear tires.
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel)
affectvehicle handling and tire life. Even with regular
use, wheels can get out of balance. Therefore,
they should be balanced as required.
If tire wear is uneven (on one side of the tire
only) or becomes abnormally excessive, check
the alignment of wheels.
Note: When replacing only two tires, always
install the new tires on the rear.
Punctured Tires
A puncture eventually causes the tire to lose pressure, which is why it is important to check
tire pressures frequently. Permanently repair
or replace punctured or damaged tires as
soon as possible.
Your tubeless tires may not leak when
penetrated, provided the object remains in the tire. If, however, you feel a sudden vibration or
ride disturbance while driving, or you suspect a tire is damaged, immediately reduce yourspeed. Drive slowly, while avoiding heavy
braking or sharp steering and, when safe to do so, stop the vehicle. Arrange to have Model X
transported to a Tesla service center, or to a
nearby tire repair center.
Note: In some cases, you can temporarily
repair small tire punctures (under 1/4” (6
mm)) using an optional tire repair kit available from Tesla. This allows you to slowly drive
Model X to Tesla or to a nearby tire repair
facility.Warning: Do not drive with a punctured
tire, even if the puncture has not causedthe tire to
deflate. A punctured tire candeflate suddenly at any time.
Flat Spots
If Model X is stationary for a long period in
high temperatures, tires can form
flat spots.
When Model X is driven, these flat spots cause
a vibration which gradually disappears as the
tires warm up and regain their original shape.
To minimize
flat spots during storage, inflatetires to the maximum pressure indicated on the tire wall. Then, before driving, release airto adjust tire pressure to the recommendedlevels.
Improving Tire Mileage
To improve the mileage you get from your
tires, maintain tires at the recommended tire
pressures, observe speed limits and advisory
speeds, and avoid:

Replacing Tires and Wheels
Tires degrade over time due to the
effects of
ultraviolet light, extreme temperatures, high
loads, and environmental conditions. It is
recommended that tires are replaced every six
years, or sooner if required.
Wheel rims and tires are matched to suit the
handling characteristics of the vehicle.
Replacement tires must comply with the
original
specification. If tires other than thosespecified are used, ensure that the load and
speed ratings marked on the tire equal or exceed those of the original
specification.
Ideally, you should replace all four tires at the same time. If this is not possible, replace the
tires in pairs (both front or both rear). When replacing tires, always re-balance and checkthe alignment of wheels.
Warning: For your safety, use only tires
and wheels that match the original
specification (see Wheels and Tires on
page 175). Tires that do not match the
original
specification can affect the
operation of the Tire Pressure Monitoring System (TPMS).
Warning: Never exceed the speed rating
of your vehicle

TPMS Malfunction
Model X 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 tire pressure
indicator light. When the system
detects a malfunction, the indicator
flashes for approximately one minute
after Model X powers on, and then
remains continuously lit. This
sequence continues upon
subsequent vehicle start-ups as long
as the malfunction exists. When the
TPMS malfunction indicator is on,
the system might not be able to
detect or signal under- and
over-
inflated tires as intended.
TPMS malfunctions can occur for a variety of
reasons, including installing replacement or
alternate tires or wheels that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction indicator light after replacing one or more tires or wheels on yourvehicle to ensure that the replacement tires or
wheels allow the TPMS to continue to function
properly.
Note: If a tire has been replaced or repaired
using a
different tire sealant than the one
available from Tesla, and a low tire pressure is
detected, it is possible that the tire sensor has
been damaged. Contact Tesla to have the fault repaired as soon as possible.

Tire Repair Kit
Your Model X has no spare tire. Depending on
the legislations that apply to the region in
which you purchased Model X, a tire repair kit
may or may not be included. If a tire repair kit
was not provided in Model X upon delivery,
you can purchase one from Tesla.
Note: Although Model X does not have a spare
tire, in the event of a
flat tire, Roadside
Assistance provides towing coverage for up to 50 miles.
The tire repair kit consists of a compressor
and a canister of tire sealant (enough to repair
one tire). When injected into a tire, the sealant
can penetrate a small puncture up to 1/4" (6 mm) to form a temporary repair.
Note: For punctures larger than 1/4” (6 mm),
severe tread damage, a damaged sidewall,
ripped tires or tires that have come
off the rim,
call Roadside Assistance.
Warning: The tire repair kit is a temporary
repair only. You must repair or replace a
damaged tire as soon as possible.Warning: Do not exceed 30 mph
(48 km/h) when driving with a tire that
has been temporarily repaired with sealant.Warning: Follow all directions and
warnings on the tire repair kit before
starting a repair.Caution: Do not drive on a deflated tire as
this can cause serious damage.Tire Sealant Canister
The tire sealant provided in the Tesla tire
repair kit is approved for use with Model X and is designed not to damage the TPMS (Tire
Pressure Monitoring System) sensors.
Therefore, you must replace it only with one of
the same type and capacity (see Replacing
the Sealant Canister on page 158). Tire
sealant canisters can be purchased from Tesla.
The tire sealant has an expiration date printed
on the outside of the canister. If the expiration
date has passed, the sealant might not work
as expected. Always replace an expired tire
sealant canister.Warning: Do not use any tire sealant
other than the one available from Tesla.
Doing so could cause tire pressure
sensors to malfunction.Warning: Always read and follow the
safety and handling instructions printed on the sealant canister.Warning: Keep tire sealant out of the
reach of children.Warning: Tire sealant can be harmful if it
contacts the eyes or if swallowed or
inhaled. If the sealant comes into contact with your eyes, immediately
flush with
water and seek medical attention if
irritation persists. If swallowed, do not
induce vomiting and seek medical assistance immediately. If inhaled, breathe
fresh air. Inhalation can cause drowsiness
and dizziness. If breathing is
affected,seek medical assistance immediately.

Inflating with Air Only
If you have a Tesla tire repair kit, follow these
steps to
inflate a tire with air:
1. Detach the power supply connector from the rear of the compressor and plug it into
the 12V power socket located in Model X
on the front of center console.
2. Release the black air hose from the compressor.
3. Attach the air hose to the valve and press the lever down to secure it in place.
4. Ensure the compressor is lying on a level
surface with the pressure gauge facing tothe side where you can read it.
5. To add air, turn on the compressor and
inflate until the desired pressure is
reached.
6. To release air, turn
off the compressor,
then press and hold the red button until
the desired pressure is reached.
Note: For your convenience, the tire repair kit
includes a selection of adapters that allow you
to
inflate other items. These adapters are
located in a compartment on the back of the compressor.
Caution: To avoid overheating, do not use
the compressor continuously for more
than eight minutes. Allow the compressor
to cool for 15 minutes between uses.Caution: The compressor runs slowly
when overheated from excessive use. Turn
it
off and allow it to cool.Temporary Tire Repair
