Inspecting and Maintaining Tires
Regularly inspect the tread and side walls for
any sign of distortion (bulges), cuts or wear.
WARNING: Do not drive Model S if a tire
is damaged, excessively worn, or inflated
to an incorrect pressure. Check tires regularly
for wear, and ensure there are no cuts, bulges or
exposure of the ply/cord structure.
Tire Wear
Model S is originally fitted with tires that have
wear indicators molded into the tread pattern.
When the tread has been worn down to 1.6 mm,
the indicators start to appear 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
Alignment
Tesla recommends rotating the tires every
8000 kms. After rotating, always check and
adjust tire pressures.
NOTE: Do not rotate tires on the Performance
Plus models.
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel) affect
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.
Punctured Tires
A puncture eventually causes the tire to lose
pressure, which is why it is important to check
tire pressures frequently. Permanently repair or
replace punctured or damaged tires as soon as
possible. Do not drive with a punctured tire,
even if the puncture has not caused the tire to
deflate. 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 a
tire is 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 Model S
transported to Tesla or to a nearby tire repair
center.
In some cases, you can temporarily repair small
tire punctures (under 6 mm) using an optional
tire repair kit available from Tesla. This allows
you to slowly drive Model S to Tesla or to a
nearby tire repair facility (see page 7.8).
WARNING: Do not drive Model S with a
punctured tire. Even if the punctured tire
has not deflated, it can suddenly deflate at any
time.
Flat Spots
If Model S is stationary for a long period in high
temperatures, tires can form flat spots. When
Model S 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, release air
to adjust tire pressure to the recommended
levels.
Driving in Low Ambient Temperatures
Tire performance reduces in low ambient
temperatures, resulting in reduced 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 for winter tire
recommendations.

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.

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.
