2015 TESLA MODEL S tire pressure

Replacing Tires and Wheels
Tires degrade over time due to the effects of
ultraviolet light, extreme temperatures, high loads, and environmental conditions. It isrecommended that tires are replaced everysix 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 those
specified are used, ensure that the load and speed ratings marked on the tire equal orexceed 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 check
the alignment of wheels.
If you replace a wheel, the TPMS (Tire
Pressure Monitoring System) sensors need to
be reset to ensure they provide accurate
warnings when tires are under- or over-
inflated (see Resetting the TPMS Sensors on
page 113).Warning: For your safety, use only tires
and wheels that match the original
specification (see Wheels and Tires on
page 143). 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's tires. The speed rating is
shown on the sidewall of your tires (see
Understanding Tire Markings on page
145).Asymmetric Tires
Model S tires are asymmetric and must be mounted on the wheel with the correctsidewall facing outward. The sidewall of thetire is marked with the word OUTSIDE. When
new tires are installed, make sure that the tires
are correctly mounted on the wheels.Warning: Road holding is seriously
impaired if the tires are incorrectly
installed on the wheels.
Tire Types
Summer Tires
Your Model S may be originally equipped with high performance summer tires. These tires
are designed for maximum dry and wet road performance. Summer tires do not performwell in winter conditions. Tesla recommendsusing winter tires if driving in cold
temperatures or on roads where snow or ice
may be present. Contact Tesla for winter tire recommendations.
Warning: In cold temperatures or on
snow or ice, summer tires do not provide
adequate traction. Selecting and installing the appropriate tires for winter conditionsis important to ensure the safety andoptimum performance of your Model S,
even when equipped with dual motors.
All-Season Tires
Your Model S may be originally equipped with all-season tires. These tires are designed to
provide adequate traction in most conditions
year-round, but may not provide the same
level of traction as winter tires in snowy or icy
conditions. All-season tires can be identified by “ALL SEASON" and/or "M+S” (mud and
snow) on the tire sidewall.
Tire Care and Maintenance
Maintenance111

Winter Tires
Your Model S is not originally equipped with
winter tires. In snowy and icy conditions, consider installing winter tires. Winter tires are
designed to increase traction in snowy or icy
conditions. When installing winter tires, always install a complete set of four tires at the sametime. Winter tires must be the same size,brand, construction and tread pattern on allfour wheels. Contact Tesla for winter tire
recommendations.Winter tires can be identified by a
mountain/snowflake symbol on the
tire's sidewall.
When driving with winter tires, you may
experience more road noise, shorter tread life, and less traction on dry roads.
Driving in Low Temperatures Tire performance is reduced in low ambient
temperatures, resulting in reduced grip and an
increased susceptibility to damage from
impacts. Performance tires can temporarily
harden when cold, causing you to hear
rotational noise for the first few miles (kms)
until the tires warm up.
Using Tire Chains Tesla has tested and approved Security Chain
Company (SCC) Model Z-563 chains for use
on the rear wheels. These chains must only be
used if your Model S has 245/45R19 rear tires
installed. Do not use chains on 21 inch tires.
When installing tire chains, follow the
instructions provided by the tire chain
manufacturer. Mount them as tightly as
possible.
When using tire chains:
• Drive slowly. Do not exceed 30 mph (48 km/h).
• Avoid heavily loading Model S (heavy loads can reduce the clearance between
the tires and the body).
• Remove the tire chains as soon as conditions allow.
Note: Tire chains are prohibited in some
jurisdictions. Check local laws before installing
tire chains.
Caution: Using non-recommended tire
chains, or using tire chains on other sized tires, can damage the suspension, body,wheels, and/or brake lines. Damagecaused by using non-recommended tire
chains is not covered by the warranty.Caution: Ensure that tire chains cannot
touch suspension components or brake
lines. If you hear the chains making
unusual noises that would indicate
contact with Model S, stop and
investigate immediately.
Tire Pressure Monitoring
Each tire should be checked monthly when
cold and inflated to the recommended pressures that are printed on the Tire and
Loading Information label located on the
driver’s door pillar (see Maintaining Tire
Pressures on page 109). If your vehicle has
tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure
label, determine the proper tire inflation
pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that displays a tire pressure
telltale (Tire Pressure Warning) on the
instrument panel when one or more of your
tires is significantly under- or over-inflated.
Accordingly, when the Tire Pressure indicator
light displays on the instrument panel alerting
of tire pressure, stop and check your tires as
soon as possible, and inflate them to the
proper pressure (see Maintaining Tire
Pressures on page 109). Driving on a
significantly under-inflated tire causes the tire
to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's
handling and stopping ability.
If Model S detects a fault with the
Tire Pressure Monitoring System
(TPMS), this indicator flashes for one
minute whenever you power on
Model S.
Note: Installing accessories that are not
approved by Tesla can interfere with the TPMS system.
Warning: The TPMS is not a substitute for
proper tire maintenance, including
manually checking tire pressures and
regularly inspecting the condition of tires.
It is the driver's responsibility to maintain
correct tire pressure, even if under- or
over-inflation has not reached the level
Tire Care and Maintenance
112Model S Owner's Manual

for the TPMS to trigger the Tire PressureWarning on the instrument panel.
Resetting the TPMS Sensors
After replacing one or more wheels, the TPMS sensors must be reset to ensure tire pressurewarnings are accurate. However, note that theTPMS sensors do not need to be reset after
replacing a tire or rotating wheels.
Note: When changing to 21" wheels
(Performance Plus models), the TPMS may
generate false tire pressure warnings. Bring
Model S to a Tesla Service center for further
adjustment.
Note: Do not reset the TPMS sensors in an
attempt to clear tire pressure warnings.
To reset TPMS sensors:
1. Inflate all tires to their recommend
pressures, as indicated on the Tire and Loading Information label located on the
driver’s door pillar.
2. Get ready to drive for ten minutes, then,
on the Model S touchscreen, touch
Controls > Settings > Service & Reset >
Tire Pressure Monitor > Reset Sensors .
3. Follow the onscreen instructions.
Replacing a Tire Sensor
If the Tire Pressure warning indicator displays frequently, contact Tesla to determine if a tiresensor needs to be replaced. Tire sensors
must be replaced by a Tesla service technician
who can perform a brief setup procedure. If a non-Tesla service center repairs or replaces atire, the tire sensor will not work until Tesla
performs the setup procedure.
TPMS Malfunction
Model S 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 S 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 oralternate tires or wheels that prevent theTPMS from functioning properly. Alwayscheck the TPMS malfunction indicator light
after replacing one or more tires or wheels on
your vehicle 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 KitYour Model S has no spare tire. Depending on
the legislations that apply to the region in which you purchased Model S, a tire repair kitmay or may not be included. If a tire repair kitwas not provided in Model S upon delivery,you can purchase one from Tesla.
Note: Although Model S 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 S andis designed not to damage the TPMS (TirePressure Monitoring System) sensors.
Therefore, you must replace it only with one
of the same type and capacity (see Replacing
the Sealant Canister on page 117). 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 withwater and seek medical attention ifirritation persists. If swallowed, do notinduce 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.
