18OWNER SAFETY INFORMATION
Punctured tiresA puncture eventually causes the tire to lose pressure, which is why it’s
important to check tire pressures frequently. Permanently repair or replace
punctured or damaged tires as soon as possible. Don’t drive with a punctured
tire, even if it isn’t deflated. 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 your tire or vehicle has been 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 the vehicle
transported to a tire repair center, or to Tesla, to have tires inspected and, if
necessary, repaired. Flat spotsIf the vehicle is stationary for a long period in high temperatures, tires can form
flat spots. When the vehicle is driven, these flat spots cause a vibration which
gradually disappears as the tires get warm 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 the vehicle, release air to adjust
tire pressure to the recommended levels. Driving In Low Ambient TemperaturesTire performance reduces in low ambient temperatures, resulting in less 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 until the tires warm up. Contact Tesla Motors for winter tire
recommendations.
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 will be adversely affected. Check tires regularly for wear
and to ensure there are no cuts, bulges or exposure of the ply/cord structure.
TEMPORARY TIRE REPAIRAs an option, you can purchase a tire repair kit from Tesla (this kit is included
only if you purchased your Model S in Maryland or Rhode Island). This kit is
designed to temporarily repair a small tire puncture just long enough for you to
drive slowly to the nearest tire repair location. Follow the instructions provided
on the kit and heed all warnings.
WARNING: Do not use any tire liquid or aerosol tire sealant other than a tire
repair kit purchased as an accessory from Tesla. Other types can cause tire
pressure sensors to malfunction.
INSPECTING AND MAINTAINING TIRESTire wearThe Model S is originally fitted with tires that have wear indicators moulded
into the tread pattern. When the tread has been worn down to 1/16”, (1.6 mm)
the indicators start appearing 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 reaches the
minimum permitted by law.Tire rotation, balance
and wheel alignmentTesla recommends rotating the tires every 6,000 miles. After rotating, always
check and adjust tire pressures.
Unbalanced wheels (sometimes noticeable
as vibration through the steering) affects 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.

REPLACING TIRES AND WHEELSTires 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 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 (shown on the tire side wall as described on page 20) equal or
exceed those of the original specification.
Ideally, you should replace all four tires at the same time. If this isn’t
possible, replace the tires in pairs (both front and both rear). When
replacing tires, always re-balance and check the alignment of wheels.Asymmetric tiresYour vehicle’s tires are asymmetric
and must be mounted on the wheel
with the correct sidewall facing
outwards. The sidewall of the tire is
marked with the words OUTSIDE.
When new tires are installed, make
sure that the tires are correctly
mounted on the wheels.
WARNING: Road holding will be seriously impaired if the tires are
incorrectly installed on the wheels.

TIRE MAINTENANCE

20OWNER SAFETY INFORMATION
UNDERSTANDING TIRE MARKINGSFederal law requires tire manufacturers to place standardized information
on the sidewall of all tires. This information identifies and describes
the fundamental characteristics of the tire and also provides the tire
identification number (TIN) for safety standard certification and in case of
a recall.1 Tire category. P indicates that the tire is for passenger vehicles
2Tire width. This 3-digit number is the width (in millimeters) of the tire from
sidewall edge to sidewall edge.
3Aspect 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 will be 102 mm.
4Tire 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.
6Load index. This 2 or 3-digit number is the weight each tire can support. This
number is not always shown.
7Speed rating. When stated, indicates the maximum speed at which the tire can
be used for extended periods.
Q 99 T 118 V 149
R 106 U 124 W 168
S 112 H 130 Y 186
8Tire 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.
10Maximum permissible inflation pressure. The maximum inflation pressure for
the tire. This pressure should not be used for normal driving.
11U.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 numbers 1712
means 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.
12Treadwear 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, will last twice as long as a tire rated at 200. See
page 21.
13Traction 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.
See page 21.
14Temperature 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. See page
21.
