Tire Care and MaintenanceMaintaining Tire Pressures
Keep tires inflated to the pressures shown on
the Tire and Loading Information label located
on the driver’s door pillar (even if it differs from
the pressure printed on the tire itself).
The Tire Pressure indicator light on the
instrument panel alerts you if one or
more tires is under- or over-inflated.
The Tire Pressure indicator light does not
immediately turn off when you adjust tire
pressure. After inflating the tire to the
recommended pressure, you must drive over
40 km/h for more than 10 minutes to activate
the Tire Pressure Monitoring System (TPMS),
which turns off the Tire Pressure indicator light.
If the indicator light flashes for one minute
whenever you power on Model S, a fault with
the Tire Pressure Monitoring System (TPMS) is
detected (see page 7.6).
Checking and Adjusting Tire Pressures
Follow these steps when tires are cold and
Model S has been stationary for over three
hours:
1.Remove the valve cap.
2.Firmly press an accurate tire pressure
gauge onto the valve to measure pressure.
3.If required, add air to reach the
recommended pressure.
4.Re-check pressure by removing and
re-attaching the tire gauge.
5.If you added too much air, release air by
pressing the metal stem in the center of the
valve.
6.Recheck the pressure with the tire gauge
and adjust if necessary.
7.Replace the valve cap to prevent dirt from
entering. Periodically check the valve for
damage and leaks.
WARNING: Under-inflation is the most
common cause of tire failures. It can
cause a tire to overheat, resulting in severe tire
cracking, tread separation, or blowout, which
causes unexpected loss of vehicle control and
increased risk of injury. Under-inflation also
reduces Battery range and tire tread life.
WARNING: Check tire pressures using an
accurate pressure gauge when tires are
cold. It takes only one mile of driving to warm
up the tires sufficiently to affect tire pressures.
Parking the vehicle in direct sunlight or in hot
weather can also affect tire pressures. If you
must check warm tires, expect increased
pressures. Do not let air out of warm tires in an
attempt to match recommended cold tire
pressures. A hot tire at or below the
recommended cold tire inflation pressure is
dangerously under-inflated.
WARNING: Do not use any tire sealant
other than the type provided in a Tesla
tire repair kit. Other types can cause tire
pressure sensors to malfunction. If your
Model S did not include a tire repair kit, you can
purchase one from Tesla Motors.

7.8MODEL S OWNERS MANUAL
Te m p o r a r y T i r e R e p a i rTire Repair Kit
Your Model S has no spare tire. Depending on
the legislations that apply to the region in
which you purchased Model S, a tire repair kit
may or may not be included. If a tire repair kit
was not provided in Model S upon delivery, you
can purchase one from Tesla.
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 6 mm to form
a temporary repair.
NOTE: For punctures larger than 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 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 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 page 7.11). 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.

Tire pressures vary depending on the type of tires fitted on Model S. Refer to the tire pressures
printed on the Tire and Loading Information label. This label is located on the driver’s door pillar
and is visible when the driver’s door is open (see page 7.3).
Winter tires (Pirelli Sottozero or Nokian Studded - P245/45R19) can be purchased from a Tesla
store.

Wheels and Tires
SPECIFICATIONS8.11 1 Tire category. P indicates that the tire is for passenger vehicles.
2 Tire width. This 3-digit number is the width (in millimeters) of the tire from sidewall edge
to sidewall edge.
3 Aspect ratio. This 2-digit number is the sidewall height as a percentage of the tread width.
So, if the tread width is 205 mm, and the aspect ratio is 50, the sidewall height is 102 mm.
4 Tire construction. R indicates that the tire is of Radial ply construction.
5 Wheel diameter. This 2-digit number is the diameter of the wheel rim in inches.
6 Load index. This 2 or 3-digit number is the weight each tire can support. This number is not
always shown.
7 Speed rating. When stated, indicates the maximum speed (in mph) at which the tire can be
used for extended periods.
Q 99 T 118 V 149
R106 U124W168
S112 H130 Y186
8 Tire composition and materials. The number of plies in both the tread area and the sidewall
area indicates how many layers of rubber coated material make up the structure of the tire.
Information is also provided on the type of materials used.
9 Maximum tire load. The maximum load which can be carried by the tire.
10 Maximum permissible inflation pressure. This pressure should not be used for normal
driving.
11 U.S. DOT Tire Identification Number (TIN). Begins with the letters DOT and indicates that
the tire meets all federal standards. The next 2 digits/letters represent the plant code where
it was manufactured, and the last 4 digits represent the week and year of manufacture. For
example, the number 1712 is used to represent the 17th week of 2012. The other numbers
are marketing codes used at the manufacturer’s discretion. This information can be used to
contact consumers if a tire defect requires a recall.
12 Treadwear grade. This number indicates the tire’s wear rate. The higher the treadwear
number is, the longer it should take for the tread to wear down. A tire rated at 400, for
example, lasts twice as long as a tire rated at 200.
13 Traction grade. Indicates a tire’s ability to stop on wet roads. A higher graded tire should
allow you to stop your vehicle in a shorter distance than a tire with a lower grade. Traction
is graded from highest to lowest as AA, A, B, and C.
14 Temperature grade. The tire’s resistance to heat is grade A, B, or C, with A indicating the
greatest resistance. This grading is provided for a correctly inflated tire, which is being used
within its speed and loading limits.
