winter tires TESLA MODEL S 2014 Owner's manual (North America)

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
Model S is originally fitted with tires that have wear indicators molded into the tread pattern.
When the tread has been worn down to 1/16” (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.
Replace a tire as soon as an indicator band becomes visible or the tread depth reachesthe minimum permitted by law.
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.
Driving in Low Ambient 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. Contact Tesla for
winter tire recommendations.
Tire Care and Maintenance

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 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 those
specified 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 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 103).Warning: For your safety, use only tires
and wheels that match the original
specification. Tires that do not match the
original specification can affect the
operation of the Tire Pressure Monitoring System (TPMS).Asymmetric Tires
Model S tires are asymmetric and must be
mounted on the wheel with the correct sidewall 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.
Winter Tires
In snowy and icy conditions, consider installing winter tires. Winter tires must be the
same size, brand, construction and tread
pattern on all four wheels. For
recommendations on winter tires, contact Tesla.
Warning: On dry roads, winter tires could
have less traction than the originally
installed tires.

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 descibed 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.
