Tire markings1, Tire widthThis three digit number gives the width in
millimeters of the tire from sidewall edge to
sidewall edge.2, Aspect ratioThis two digit number, known as the aspect
ratio or profile, gives 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.3, Tire constructionR indicates that the tire is of Radial ply
construction.4, Wheel diameterThis two digit number is the diameter of the
wheel rim in inches.5, Load indexThis two or three digit number is the tire's load
index. It is a measurement of how much
weight each tire can support. This number is
not always shown.6, Speed ratingThe speed rating, when stated, denotes the
maximum speed at which the tire should be
used for extended periods. The ratings range
from 99 mph to 186 mph. These ratings are
listed in the following table.

Technical specifications
Tire placard/labelThe tire information label on the pillar behind
the driver’s door contains the following
information:
• The maximum number of occupants for
the vehicle.
• The vehicle capacity weight, which
includes the weight of the driver,
passengers and cargo.
• The size of the tires with which the
vehicle was originally equipped.
• Cold inflation pressures for the front and
rear tires.
Note: The label must not be changed, even if
different wheels are fitted at a later stage.Steps for determining correct load
limit
WARNING: Do not exceed the vehicle
capacity weight (the total weight of
driver, passenger and cargo) given.
S
WARNING: Overloading the vehicle will
have an adverse affect on braking and
handling characteristics, which could
compromise your safety.
S
1. Locate the statement “The combined weight of occupants and cargo should
neve r exce e d 2 50 kg or 5 51 l bs ” as s h ow n
on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
3. Subtract the combined weight of the driver and passengers from 250 kg or 551
lbs (weight given on placard).
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if there will be two
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 251 lbs: (551 - 300 (2 x
150) = 251 lbs).

5. Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
6. Your vehicle should never be used to tow a trailer.
The number and weight of passengers will
affect the cargo and luggage load capacity. In
the example above, the cargo and luggage
load capacity is 251 lbs. However, if only one
occupant is in the vehicle, the luggage load
capacity will increase. If the vehicle carries
one 150 lb person, the luggage load capacity
will increase to 401 lbs (551 - 150 = 401 lbs).
Note: If the passengers weigh more, the
luggage load capacity will decrease.Uniform tire quality gradingThe following information relates to the tire
grading system developed by the National
Highway Traffic Safety Administration
(NHTSA) which will grade tires by tread wear,
traction and temperature performance.
Note: Tires that have deep tread, and winter
tires, are exempt from these marking
requirements.
Quality grades, where applicable, can be
found on the tire sidewall between the tread
shoulder and maximum section width. For

pressure telltale illuminates, you should stop
and check your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces
Battery range and tire tread life, and may
affect the vehicle’s handling and stopping
ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-inflation has not
reached a level to trigger illumination of the
TPMS tire pressure telltale.Checking tire pressures
WARNING: Tire pressures should be
checked using an accurate pressure
gauge when cold. Under-inflation is the most
common cause of tire failures and may result
in severe tire cracking, tread separation or
“blowout”, with unexpected loss of vehicle
control and increased risk of injury.
S
Check the pressures when the tires are cold.
Be aware that it only takes 1 mile (1.5 km) of
driving to warm up the tires sufficiently to
affect the tire pressures. If it is necessary to
check the tires when they are warm, you
should expect the pressures to have
increased. Do not let air out of warm tires in
an attempt to match the recommended cold
tire pressures.
Note: When adjusting tire pressures, you can
display tire pressure values on the Touch
Screen’s tire pressure screen. However, the values displayed by the Touch Screen will not
be updated until you place the car in drive
long enough for the tire pressure monitoring
sensors to take new readings. For details,
refer to the Touch Screen Users Manual
provided in your owners package.
Always inflate your tires to the Tesla Motors
recommended inflation pressure even if it is
different from the maximum inflation
pressure information found on the tire itself.
For the correct tire pressures, refer to
Specifications and tire pressures, page 11-4
.
The following procedure should be used to
check and adjust tire pressures: 1. Remove the cap from the valve, then firmly press the tire gauge onto the valve
and measure the pressure.
2. If required add air to reach the required pressure.
3. Check the pressure by removing the tire gauge and then re-attaching it.
Note: Failure to remove and re-attach the
gauge to the valve could cause the gauge
to show an incorrect reading.
4. If too much air is added, air can be released by pushing on the metal stem in
the center of the valve.
5. Recheck the pressure with the tire gauge and adjust if necessary.
6. Refit the valve cap.
Va l ve sFit the valve caps securely to prevent dirt
from entering the valve. Periodically check
the valve for damage and leaks.
Tire wear
WARNING: The tires should be
regularly checked for wear and to make
sure that there are no cuts, bulges or
exposure of the ply/cord structure. Do not
drive with tires which are worn or damaged.
The safety of the vehicle and occupants will
be adversely affected.p
Tires fitted as original equipment have wear
indicators moulded into the tread pattern.
When the tread has been worn down to 1/16”
(inch). 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.
A tire must be replaced as soon as an
indicator band becomes visible or the tread
depth reaches the minimum permitted by
legislation.
