steering TESLA MODEL S 2014 Quick Guide (North America) 

Tires and Wheels
SAFETY INFORMATION19
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 1/16”
(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.
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 can be adversely affected. Check
tires regularly for wear and to ensure there are
no cuts, bulges or exposure of the ply/cord
structure.
Tire Rotation, Balance, and Wheel
Alignment
Tesla recommends rotating the tires every
5000 miles (8000 km). 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 a Tesla service center, or to a
nearby tire repair center.
In some cases, you can temporarily repair small
tire punctures (under 1/4”/6 mm) using an
optional tire repair kit available from Tesla. This
allows you to slowly drive Model S to a Tesla
service center or to a nearby tire repair facility.
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 warm up 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 is reduced 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.
