Inspecting and Maintaining TiresRegularly inspect the tread and side walls for
any sign of distortion (bulges), foreign objects,
cuts or wear.Warning: Do not drive Model X 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 3 mm are more likely to hydroplane in
wet conditions and should not be used. Tires
with a tread depth less than 4 mm do not
perform well in snow and slush and should not
be used when driving in winter conditions.
Model X is originally
fitted with tires that have
wear indicators molded into the tread pattern. When the tread has been worn down to 3 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. For optimal performance and safety,
Tesla recommends replacing tires before the
wear indicators are visible.
Tire Rotation, Balance, and Wheel Alignment
Model X tires cannot be rotated, as tires are
asymmetrical and front tires are a
differentsize from rear tires.
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 X
transported to a Tesla Service Center, or to a nearby tire repair center.
Note: 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 X to Tesla or to a nearby tire repair facility.Warning: Do not drive with a punctured
tire, even if the puncture has not caused the tire to
deflate. A punctured tire candeflate suddenly at any time.
Flat Spots
If Model X is stationary for a long period in
high temperatures, tires can form
flat spots.
When Model X 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:

Removing and Installing Lug Nut Covers
If your Model X is equipped with lug nut
covers, you must remove them to access the
lug nuts.
To remove a lug nut cover:
1. Insert the curved part of the lug nut cover
tool (located in your glovebox) into the hole at the base of the Tesla "T".
2. Maneuver the lug nut cover tool so that it
is fully inserted into the hole in the lug nut
cover.
3. Twist the lug nut cover tool so that the
curved part is touching the middle of the
lug nut cover.
4. Firmly pull the lug nut tool away from the
wheel until the lug nut cover is released.
To install the lug nut cover, align it into
position and push firmly until it fully snaps into
place.
Seasonal Tire Types
Summer Tires
Your Model X may be originally equipped with
high performance summer tires, all season
tires, or winter tires. Summer tires and all
season tires are designed for maximum dry
and wet road performance but are not designed to perform well in winter conditions.
Tesla recommends using winter tires if driving
in cold temperatures or on roads where snow
or ice may be present. If not equipped with
winter tires, contact Tesla for winter tire
recommendations.Warning: In cold temperatures or on
snow or ice, summer tires do not provide adequate traction. Selecting and installingthe appropriate tires for winter conditions
is important to ensure the safety and
optimum performance of your Model X,
even when equipped with dual-motors.
All-Season Tires
Your Model X may be originally equipped with
all-season tires. These tires are designed to provide adequate traction in most conditions
year-round, but may not provide the same level of traction as winter tires in snowy or icy
conditions. All-season tires can be
identifiedby “ALL SEASON" and/or "M+S” (mud and
snow) on the tire sidewall.
Winter Tires
Use winter tires to increase traction in snowy
or icy conditions. When installing winter tires,
always install a complete set of four tires at
the same time. Winter tires must be the same
size, brand, construction and tread pattern on all four wheels. Contact Tesla for winter tire
recommendations.
When equipped with winter tires, refer to the
tire warning label on the door pillar.
Winter tires can be identified by amountain/snowflake symbol on the
tire
