Displaying Tire Pressures
Tire pressures display on the touchscreen by touching Controls > Service, or use the mobile app. The pressure of each tire
displays in the visualization of CybertruckModel SModel X, in addition to the time the tire pressures were last read by the
system.
The touchscreen also displays your vehicle's recommended cold tire pressures so you can easily determine how much to
inflate your tires.
To choose whether to display tire pressures using Bar or PSI, touch Controls > Display > Tire Pressure.
NOTE: You may need to drive briefly before the visualization displays the tire pressure values.

Maintaining Tire Pressures

Keep tires inflated to the recommended pressures, even if it differs from the pressure printed on the tire itself. The Tire and
Loading Information label on the center door pillar is visible when the driver door is open and represents a nominal driving
scenario in which the vehicle is carrying cargo in the front trunk and up to five passengers. When carrying heavy loads, up to
the vehicle's GVWR, in a Cybertruck equipped with All Terrain tires, the tire pressures should be increased.

Maintenance
The Low Tire Pressure indicator light on the touchscreen alerts you if a tire is under-inflated. This light does not
immediately turn off when you adjust tire pressure. After inflating the tire to the recommended pressure, you
must drive over 15 mph (25 km/h) for a short amount of time to activate the Tire Pressure Monitoring System
(TPMS), which turns off the Low Tire Pressure indicator light.

If the indicator light flashes for one minute whenever you power on CybertruckModel SModel X, a fault with the TPMS is
detected.
Your vehicle’s tire pressures will drop in cold ambient temperatures. If the TPMS indicator light appears, inflate the tires before
driving. The tires will lose approximately one PSI for every 10° F (6° C) drop in outside temperature. Proper tire pressures help
protect tires from potholes and improve range and tire longevity when properly inflated.
WARNING: The Low Tire Pressure indicator light alerts you only in situations when a tire is below the recommended
threshold (as indicated on the Tire and Loading Information label) under normal driving conditions. It does not alert you
when a tire is under-inflated based on the load you are carrying.
WARNING: Under-inflation is the most common cause of tire failures and can cause a tire to overheat, resulting in severe
tire cracking, tread separation, or blowout. This may lead to unexpected loss of vehicle control and increased risk of
injury. Under-inflation also reduces the vehicle's range and tire tread life.

Checking and Adjusting Tire Pressures
WARNING: Check tire pressures using an accurate pressure gauge when tires are cold. It takes only about one mile
(1.6 km) of driving to warm up the tires sufficiently to affect tire pressures. Parking the vehicle in direct sunlight or in hot
weather can also affect tire pressures. If you must check warm tires, expect increased pressures. Do not let air out of
warm tires in an attempt to match recommended cold tire pressures. A hot tire at or below the recommended cold tire
inflation pressure is dangerously under-inflated.
Follow these steps when tires are cold and CybertruckModel SModel X has been stationary for over three hours:
1. Refer to the Tire and Loading Information label located on the driver’s center door pillar for the target tire pressure.
2. Remove the wheel cover (see Removing and Installing Wheel Covers on page 1019).
3. Remove the valve cap.
4. Firmly press an accurate tire pressure gauge onto the valve to measure pressure.
NOTE: You can also view tire pressures on the touchscreen.

1014

Owner's Manual

Maintenance

5. If required, add or remove air to reach the recommended pressure.
NOTE: You can release air by pressing the metal stem in the center of the valve.
6. Re-check pressure using the accurate tire gauge.
7. Repeat steps 5 and 6 as necessary until the tire pressure is correct.
8. Reinstall the valve cap to prevent dirt from entering. Periodically check the valve for damage and leaks.
9. Reinstall the wheel cover.

Tire Pressure Monitoring
Each tire should be checked monthly when cold and inflated to the recommended pressures (see Maintaining Tire Pressures
on page 1013). If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure
label, determine the proper tire inflation pressure for those tires.
When the Tire Pressure indicator light displays on the touchscreen to alert you about tire pressure, stop and check your tires
as soon as possible, and inflate them to the proper pressure (see Maintaining Tire Pressures on page 1013). Driving on a
significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces range
efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.
If CybertruckModel SModel X detects a fault with the TPMS, this indicator flashes for one minute whenever you
power on CybertruckModel SModel X.

NOTE: Installing accessories that are not approved by Tesla can interfere with the TPMS.
WARNING: The TPMS is not a substitute for proper tire maintenance, including manually checking tire pressures and
regularly inspecting the condition of tires. It is the driver's responsibility to maintain correct tire pressure, even if underinflation has not reached the level for the TPMS to trigger the Tire Pressure indicator light on the touchscreen.

Owner's Manual

1015

Maintenance
Inspecting and Maintaining Tires
Regularly inspect the tread and side walls for any sign of distortion (bulges), foreign objects, cuts or wear.
WARNING: Do not drive CybertruckModel SModel 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.
To improve the mileage you get from your tires, maintain tires at the recommended tire pressures, observe speed limits and
advisory speeds, and avoid:
• Pulling away quickly, or hard acceleration.
• Fast turns and heavy braking.
• Potholes and objects in the road.
• Hitting curbs when parking.
• Contaminating tires with fluids that can cause damage.

Tire Wear
Adequate tread depth is important for proper tire performance.
CybertruckModel SModel X is originally fitted with tires that have wear indicators molded into the tread pattern. When the
tread has been worn down to 2/32” (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. For optimal performance and safety, Tesla recommends
replacing tires before the wear indicators are visible.
Tires with a tread depth less than 4/32” (3 mm) are more likely to hydroplane and should not be used when driving in wet
conditions. 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.
To improve vehicle handling characteristics and minimize hydroplaning in wet conditions, put tires with the most tread on the
rear of the car.

Tire Rotation, Balance, and Wheel Alignment
Tesla recommends rotating the tires every 6,250 miles (10,000 km) or if tread depth difference is 2/32 in (1.6 mm) or greater,
whichever comes first.
Tire rotation is an essential part of tire maintenance. It helps maintain an even tread wear pattern which enhances the tire's
overall wear quality, decreases road noise and maximizes tire life.
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 wheel alignment.
Punctured Tires
A puncture eventually causes the tire to lose pressure, which is why it is important to check tire pressures frequently.
Permanently repair (if safe to do so) 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 your speed. Drive slowly,
while avoiding heavy braking or sharp steering and, when safe to do so, stop the vehicle and contact Roadside Assistance.
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 CybertruckModel SModel X to a nearby tire repair facility.
WARNING: Do not drive with a punctured tire that has not been repaired, even if the puncture has not caused the tire to
deflate. A punctured tire can deflate suddenly at any time.

1016

Owner's Manual

Maintenance
Flat Spots
If CybertruckModel SModel X is stationary for a long period, tires can form flat spots. When CybertruckModel SModel 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, inflate tires to the maximum pressure indicated on the tire's sidewall. Then, before
driving, release air to adjust tire pressure to the recommended levels.
Tire Pressure Monitoring System (TPMS)
After replacing one or more wheels (but not after just replacing a tire or rotating wheels), the TPMS sensors are reset to
ensure tire pressure warnings are accurate. TPMS sensors reset automatically after driving over 15 mph (25 km/h) for longer
than 10 minutes.
NOTE: After replacing a wheel, false tire pressure warnings may display before you've driven 15 mph (25 km/h) for longer than
10 minutes.
WARNING: If your CybertruckModel SModel X is equipped with aftermarket tires that differ in size from those printed on
the Tire and Loading Information Label (see Vehicle Loading on page 1046), it is the driver's responsibility to determine
the correct tire pressure. Do not drive on public roads when tires are not inflated to the correct pressure.
WARNING: Do not depend on TPMS sensors to accurately determine pressures and trigger alerts. It is the driver's
responsibility to maintain correct tire pressures (see Maintaining Tire Pressures on page 1013). Over or under-inflated
tires can result in loss of control or tire damage, which can lead to serious injury.
TPMS Malfunction
CybertruckModel SModel X has also been equipped with a TPMS malfunction indicator to indicate when the system is not
operating properly.
The TPMS malfunction indicator is combined with the tire pressure indicator light. When the system detects a
malfunction, the indicator flashes for approximately one minute, then remains continuously lit. This sequence
continues upon subsequent vehicle start-ups as long as the malfunction exists. When the TPMS malfunction
indicator is on, the system might not be able to detect or signal under-inflated tires as intended.

TPMS malfunctions can occur for a variety of reasons, including installing replacement or alternate tires or wheels that prevent
the TPMS from functioning properly. Always check the TPMS malfunction indicator light after replacing one or more tires or
wheels on your vehicle to ensure that the replacement tires or wheels allow the TPMS to continue to function properly.
NOTE: If a tire has been replaced or repaired using a different tire sealant than the one available from Tesla, and a low tire
pressure is detected, it is possible that the tire sensor has been damaged. Use the mobile app to schedule a service
appointment to have the fault repaired as soon as possible.
Replacing a Tire Sensor
If the Tire Pressure warning indicator displays frequently, schedule a service appointment to determine if a tire sensor needs
to be replaced. Non-Tesla Service Center must replace using a Tesla OEM sensor.

Seasonal Tire Types
Understand Your Tire Type
The type of tires that your vehicle is originally equipped with depends on vehicle model and market region. It is important to
understand the capabilities of your vehicle's tires and whether they are suited for summer, all-season, or winter driving. Check
the information on the sidewall of a tire for information about a tire's performance characteristics (see Tire Pressures on page
1013).
Summer and All-Season 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. All-season 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 identified by “ALL
SEASON" and/or "M+S” (mud and snow) on the tire sidewall.

Owner's Manual

1017

Maintenance
If driving in cold temperatures or on roads where snow or ice may be present, Tesla recommends using winter tires.
WARNING: In cold temperatures or on snow or ice, summer and all-season tires do not provide adequate traction.
Selecting and installing the appropriate tires for winter conditions is important to ensure the safety and optimum
performance of your CybertruckModel SModel X.
All-Terrain Tires
Use all-terrain tires if you regularly drive on gravel and dirt roads. All-terrain tires are suitable for driving on both paved roads
(city streets, highways, etc.) as well as off-road (sand, dirt, mud, etc.). All-terrain tires must be the same diameter, brand,
construction and tread pattern on all four wheels.
When driving with all-terrain tires, you may experience more road noise, shorter tread life, and less traction on dry roads.
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 diameter, brand, construction and tread pattern on all four wheels.
Winter tires can be identified by a mountain/snowflake symbol on the tire's sidewall.

When driving with winter tires, you may experience more road noise and shorter tread life.

Driving in Low Temperatures
Tire performance is reduced in low ambient temperatures, resulting in reduced grip and an increased susceptibility to damage
from impacts. Performance tires (summer applications) have reduced traction in ambient temperatures below 5° C40° F (5°
C), and are not recommended in snow/ice conditions. Performance tires can temporarily harden when cold, causing you to
hear rotational noise for the first few miles (kilometers) until the tires warm up.

Tire Chains
Only use tire chains on the REAR tires.
Tesla has tested and approved the following tire chains to increase traction in snowy conditions. Install tire chains on rear tires
only. The approved tire chains can be purchased from Tesla.
CAUTION: You must remove wheel covers before installing tire chains. Failure to do so can cause damage not covered
by the warranty.
Tire Size

Recommended Chain

20"

When installing tire chains, follow the instructions and warnings provided by the tire chain manufacturer. Mount them evenly
and as tight as possible.
When using tire chains:
• Inspect the tire chains for loose fittings and damaged links before each use.
• Set air suspension to Medium and turn off the Preferred Ride Height to Low setting (see Suspension on page 870).
• Avoid heavily loading CybertruckModel SModel X (heavy loads can reduce the clearance between the tires and the body).
• Do not drive the vehicle without the chains properly installed.
• Drive slowly. Do not exceed 30 mph (48 km/h).
• Remove the tire chains as soon as conditions allow.
NOTE: Tire chains are prohibited in some jurisdictions. Check local laws before installing tire chains.
1018

Owner's Manual

Maintenance
CAUTION: Using non-recommended tire chains, or using tire chains on other sized tires can damage the suspension,
body, wheels, and/or brake lines. Damage caused by using non-recommended tire chains, or incorrectly installing tire
chains, is not covered by the warranty.
CAUTION: Never deflate your tires to put on tire chains. When re-inflated, the chains might fit too tightly and cause tire
damage.
CAUTION: Install tire chains on rear tires only. Installing chains on front tires can cause damage.
CAUTION: Ensure that the tire chains cannot touch suspension components or brake lines. If you hear the chains making
unusual noises that would indicate contact with CybertruckModel SModel X, stop and investigate immediately.

Removing and Installing Wheel Covers

Understanding Tire Markings
Laws require tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and
describes the fundamental characteristics of the tire. It also provides the tire identification number (TIN) for certification of
safety standards, and in case of a recall.

NOTE: You can identify a Tesla-approved tire by the "T-mark" specification on the tire's sidewall (for example, T0, T1,
T2).Tesla-approved tires are designed to work with your vehicle and optimize performance, safety, reliability, and durability.
For more information about Tesla-approved replacement tires, refer to the Service Manual.
1. Tire category: P (passenger), LT (light truck), or None (hard metric) indicates the tire classification and corresponding load
classification.
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.

Owner's Manual

1023

Maintenance
7. Speed rating: When stated, indicates the maximum speed (in mph) at which the tire can be used for extended periods.
Q=99 mph (160 km/h), R=106 mph (170 km/h), S=112 mph (180 km/h), T=118 mph (190 km/h), U=124 mph (200 km/h),
H=130 mph (210 km/h), V=149 mph (240 km/h), W=168 mph (270 km/h), Y=186 mph (300 km/h), (Y)=vehicle's top speed
(exceeds the "Y" rating).
8. Load range: Shown as Standard Load (SL) or Extra Load (XL), the load range determines how much weight your tires can
support at a specified tire pressure. When replacing tires, only use tires of the same load range. If towing with snow tires,
ensure they are the same load range of the tires your vehicle came equipped with.
9. 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.
10. Maximum tire load: The maximum load which can be carried by the tire.
11. Maximum permissible inflation pressure: This pressure should not be used for normal driving.
12. 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.
13. 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.
14. 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.
15. 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.

Owner's Manual

Maintenance
Uniform Tire Quality Grading
The following information relates to the tire grading system developed by the National Highway Traffic Safety Administration
(NHTSA), which grades tires by tread wear, traction and temperature performance. Tires that have deep tread, and winter
tires, are exempt from these marking requirements.
Where applicable, quality grades are found on the tire’s sidewall between the tread shoulder and maximum section width. For
example:
• TREADWEAR 180
• TRACTION AA
• TEMPERATURE A
The quality grades are described next.
NOTE: In addition to the marking requirements, passenger car tires must conform to Federal Safety Requirements.
Treadwear
The 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 wears one and a half times better on a government test course than a tire graded 100. The
relative performance of tires depends on the actual conditions of their use, however, and can depart significantly from the
norm due to variations in driving habits, service practices, road characteristics, and climate.
Traction
The traction grades, from highest to lowest, are: AA, A, B, and C. These grades represent a tire’s ability to stop on wet
pavement as measured under controlled conditions on test surfaces of asphalt and concrete. A tire marked C might have poor
traction performance.
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.
WARNING: The traction grade assigned to the tire is based on straight-ahead braking tests, and does not include:
acceleration, cornering, hydroplaning or peak traction characteristics.
Temperature
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 tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
The grade C corresponds to the minimum level of performance that all passenger car tires must meet under the Federal Motor
Safety Standard No. 109. Grades B and A represent levels of performance on the laboratory test wheel that exceed the
minimum requirements.
WARNING: A tire’s temperature grade 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.
