Inspecting and Maintaining TiresRegularly 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
Adequate tread depth is important for proper
tire performance. Tires with a tread depth less
than 4/32” (3 mm) are more likely to
hydroplane in wet conditions and should not
be used. Tires with a tread depth less than
5/32” (4 mm) do not perform well in snow and
slush and should not be used when driving in
winter conditions.
Model S is originally
fitted with tires that have
wear indicators molded into the tread pattern. When the tread has been worn down to 4/32”(3 mm), the indicators start to appear at thesurface of the tread pattern, producing the
effect of a continuous band of rubber across
the width of the tire. For optimal performance and safety, Tesla recommends replacing tires
before the wear indicators are visible.
Tire Rotation, Balance, and Wheel Alignment
Tesla recommends rotating the tires every
5000 miles (8000 km).
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel)
affectvehicle 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.
Note: When replacing only two tires, always
install the new tires on the rear.
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.
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 yourspeed. 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, or to a nearby tire
repair center.
Note: 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 Tesla or to a nearby tire repair
facility.Warning: Do not drive with a punctured
tire, even if the puncture has not causedthe tire to
deflate. A punctured tire candeflate suddenly 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
flat spots during storage, inflatetires to the maximum pressure indicated on the tire wall. Then, before driving, release airto adjust tire pressure to the recommended
levels.
Improving Tire Mileage
To improve the mileage you get from your
tires, maintain tires at the recommended tire
pressures, observe speed limits and advisory
speeds, and avoid:
Replacing Tires and Wheels
Tires 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.
Wheel rims and tires are matched to suit the
handling characteristics of the vehicle.
Replacement tires must comply with the
original
specification. If tires other than thosespecified are used, ensure that the load and
speed ratings marked on the tire equal or
exceed those of the original
specification.
Ideally, you should replace all four tires at the same time. If this is not possible, replace the
tires in pairs (both front or both rear). When
replacing tires, always re-balance and check
the alignment of wheels.
If you replace a wheel, the TPMS (Tire Pressure
Monitoring System) sensors need to be reset to ensure they provide accurate warnings
when tires are under- or
over-inflated (see
Resetting the TPMS Sensors on page 139).
Warning: For your safety, use only tires
and wheels that match the original
specification (see Wheels and Tires on
page 169). Tires that do not match the
original
specification can affect the
operation of the Tire Pressure Monitoring System (TPMS).
Warning: Never exceed the speed rating
