2015 TESLA MODEL S winter tires

Inspecting and Maintaining Tires
Regularly inspect the tread and side walls for
any sign of distortion (bulges), cuts or wear.Warning: Do not drive Model S 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 tohydroplane in wet conditions and should notbe used. Tires with a tread depth less than5/32” (4 mm) do not perform well in snow
and slush and should not be used when
driving in winter conditions.
Model S is originally fitted with tires that have
wear indicators molded into the tread pattern.
When the tread has been worn down to 2/32”
(1.6 mm), the indicators start to appear at the surface 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
Tesla recommends rotating the tires every 5000 miles (8000 km).
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel) affect
vehicle 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. Do not drive with a
punctured tire, even if the puncture has not caused the tire to deflate. A punctured tire
can deflate suddenly at any time.
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 your
speed. Drive slowly, while avoiding heavy
braking or sharp steering and, when safe to do
so, stop the vehicle. Arrange to have Model S
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 S to Tesla or to a nearby tire repair facility.Warning: Do not drive Model S with a
punctured tire. Even if the punctured tire has not deflated, it can suddenly deflate
at any time.
Flat Spots
If Model S is stationary for a long period in
high temperatures, tires can form flat spots. When Model S is driven, these flat spots causea vibration which gradually disappears as thetires warm up and regain their original shape.
To minimize the flat spots during storage,
inflate tires to the maximum pressure
indicated on the tire wall. Then, before driving, release air to adjust tire pressure to the
recommended levels.
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:
• Pulling away quickly, or hard acceleration.
• Fast turns and heavy braking. • Potholes and objects in the road.
• Hitting curbs when parking.
• Contaminating tires with fluids that can cause damage.

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.

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

Uniform Tire Quality Grading
The following information relates to the tire
grading system developed by the National
Highway Traffic Safety Administration
(NHTSA), which grades tires by tread wear,
traction and temperature performance. Tires
that have deep tread, and winter tires, are
exempt from these marking requirements.
Where applicable, quality grades are found on
the tire’s sidewall between the tread shoulder and maximum section width. For example:
• TREADWEAR 180
• TRACTION AA
• TEMPERATURE A
The quality grades are described next. Note: In addition to the marking requirements,
passenger car tires must conform to Federal Safety Requirements.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified government test course.
For example, a tire graded 150 wears one and
a half times better on a government test
course than a tire graded 100. The relative
performance of tires depends on the actual
conditions of their use, however, and can depart significantly from the norm due to
variations in driving habits, service practices, road characteristics, and climate.
Traction
The traction grades, from highest to lowest,
are: AA, A, B, and C. These grades represent a
tire’s ability to stop on wet pavement as
measured under controlled conditions on test
surfaces of asphalt and concrete. A tire
marked C might have poor traction performance.Warning: Defective tires are dangerous.
Do not drive if a tire is damaged,
excessively worn, or is inflated to an
incorrect pressure. The safety of the
vehicle and occupants can be adversely
affected. Check tires regularly for wear
and to ensure there are no cuts, bulges or
exposure of the ply/cord structure.Warning: The traction grade assigned to
the tire is based on straight-ahead
braking tests, and doesn’t include:acceleration, cornering, hydroplaning or
peak traction characteristics.
Temperature
The temperature grades are A (the highest), B, and C, representing the tire’s resistance tothe generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test wheel. Sustained high temperature cancause the tire to degenerate and reduce tirelife, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to the minimum
level of performance that all passenger car
tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A
represent levels of performance on the
laboratory test wheel that exceed the
minimum requirements.
Warning: A tire’s temperature grade is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
