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.

Wheels and tires11-6Technical specifications7, U.S DOT Tire Identification Number
(TIN)This begins with the letters DOT and
indicates that the tire meets all federal
standards. The next two numbers or letters
are the plant code where it was
manufactured, and the last four numbers
represent the week and year the tire was
built. For example, the numbers 1706 means
the 17th week of 2006. 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.8, Maximum permissible inflation
pressureThe maximum inflation pressure for the tire.
This pressure should not be used for normal
driving.
9, Treadwear gradeThis 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 200.10, Traction gradeThis letter indicates a tire's ability to stop on
wet pavement. A higher graded tire should
allow you to stop your vehicle on wet roads in
a shorter distance than a tire with a lower
grade.
Traction is graded from highest to lowest as
AA, A, B, and C.11, Temperature gradeHeat resistance grading. The tires resistance
to heat is grade A, B, or C, with A indicating
the greatest resistance to heat. This grading
is provided for a correctly inflated tire, which
is being used within its speed and loading
limits.12, Tire composition and materialsThe number of plies in both the tread area,
and the sidewall area, indicates how many

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
example:TREADWEAR 180
TRACTION AA
TEMPERATURE A
Roadster OHB.book Page 7 Th ursday, October 2, 2008 8:59 AM
Page 98 of 115
Wheels and tires11-8Technical specificationsIn addition to the marking requirements,
passenger car tires must conform to Federal
Safety Requirements.
Note: Your vehicle is equipped with
directional tires. Therefore, you can see the
tire markings only on the outside of the
passenger tires. TreadwearThe 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 would wear
one and a half times as well on a government
test course as a tire graded 100. The relative
performance of tires depends on the actual
conditions of their use, however, and may
depart significantly from the norm due to
variations in driving habits, service practices,
and differences in road characteristics and
climate.Tra c t i o n
WARNING: The traction grade assigned
to this tire is based on straight-ahead
braking tests, and does not include;
acceleration, cornering, hydroplaning or peak
traction characteristics.
S
The traction grades, from highest to lowest,
are; AA, A, B, and C. These grades represent
a tire’s ability to stop on a wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.
Te m p e r a t u r e
WARNING: The temperature grade for
this tire 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. S
The temperature grades are A (the highest),
B, and C, representing the tire's resistance to
the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car tires
must meet under the Federal Motor Safety
Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.Tire care
WARNING: Defective tires are
dangerous. Do not drive if any tire is
damaged, is excessively worn, or is inflated to
an incorrect pressure.
S
Always consider tire conditions when driving,
and regularly inspect the tread and side walls
for any sign of distorti on (bulges), cuts or
wear.
The way you drive has a significant influence
on your safety and on the life of your tires.
Cultivate good habits for your own benefit:
• Observe posted speed limits.
• Avoid fast starts, stops and turns.
• Avoid potholes and objects in the road.
• Do not run over curbs or hit the tire
against the curb when parking.
Caution: Avoid contaminating tires with
vehicle fluids that can cause damage.Tire pressure information
WARNING: If the vehicle has been
parked in strong sunlight or used in high
ambient temperatures, do not reduce the tire
pressures. Move the vehicle into the shade and
allow the tires to cool before checking.
S
Correctly inflated tires will ensure that you
enjoy the best combination of vehicle range,
tire life, ride comfort and road handling.
Tire pressure should be checked when the
tires are cold. Inflate each tire to the pressure
recommended by Tesla Motors on the vehicle
placard, or tire inflation pressure label.
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS) that
illuminates a tire pressure telltale when one or
more of your tires is significantly
under-inflated. Accordingly, when the low tire
Roadster OHB.book Page 8 Th ursday, October 2, 2008 8:59 AM
Page 99 of 115
Wheels and tires
11-9
Technical specifications
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.

Wheels and tires11-10
Technical specifications
Note: If tire wear is uneven (on one side of the
tire only) or becomes abnormally excessive,
the wheel alignment should be checked.Age degradationTires 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.Punctured tiresYour vehicle is fitted with tubeless tires,
which may not leak when penetrated,
provided the object remains in the tire.
If, however, you feel a sudden vibration or ride
disturbance while driving, reduce your speed
and when safe to do so, stop and check for
the cause of the vibration.
A puncture will eventually cause the tire to
lose pressure, which is why frequent checking
of tire pressures is important. Punctured or
damaged tires must be permanently repaired
or replaced as soon as possible.
Directional tires
WARNING: Road holding will be
seriously impaired if directional tires
are incorrectly installed.
S
Your vehicle is fitted with directional tires. An
arrow on the tire wall shows the direction of
rotation. These tires must be fitted to rotate
in the direction of the arrow when the vehicle
is moving forward.
For this reason, wheels must not be swapped
from one side of the vehicle to the other, and
replacements must be fitted with regard for
axle/wheel rotation.Replacement wheels and tires
WARNING: For your safety, it is
recommended that only wheels and
tires that match the original specification are
used on the vehicle.
S
Wheel rims and tires are matched to suit
handling characteristics of the vehicle.
Always check that replacement tires 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) equal or exceed those of the
original specification.
For the specification of the original wheels
and tires installed on the vehicle, refer to
Specifications and tire pressures, page 11-4.
Note: Different sizes are specified for front
and rear tires. Therefore, wheels must not be
swapped from front to rear or vice versa.Winter tires and chains
WARNING: For your safety, it is
recommended that if winter tires or
chains are needed, you use only those that
are recommended by Tesla Motors.
S
Tesla recommends the following winter tires
and tire pressure settings:
• Front: Pirelli 210 Snowsport 195/50/R16
84H at 25 PSI
• Rear: Pirelli 240 Snowsport 215/45/R17
91H at 36 PSI
If snow chains are necessary, Tesla
recommends PEWAG Neon x3 Montage.
