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
