WARNING: Do not drive Model Y 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
Page 188 of 298

When a tire set becomes worn, replace all four tires at
the same time. Choose a Tesla-approved tire which is
designed
specifically for your vehicle. Most Tesla-
approved tires can be
identified with a Tx specification
(for example, T0, T1, T2). Tesla-approved tires are
designed to reduce road noise and optimize handling, ride, and range. Contact Tesla Service for information.
If tires need to be replaced early, for example due to a
flat tire, we recommend replacing the tires in pairs
unless the other tires are within
2/32 in (1.5 mm) of tread
depth of the new tire. When replacing tires, it is important to match the brand and model of the older
tires. Always place a pair of new tires on the rear if all four tires are the same size. Always balance the wheel and tire after replacing a tire. Consult with a professional tire retailer and installer for further guidance.
If you
replace your tires or install different ones, reset the tire
configuration (see Tire Configuration on page 188). This
resets the learned tire settings and improves the driving
experience on your new tires.
NOTE: Regardless of the number of tires replaced, a
complete set of matching tires is recommended for optimum performance.
If tires other than those specified are used, ensure that
the load and speed ratings marked on the tire
(see
Understanding Tire Markings on page 216) equal or
exceed those of the original
specification.
For the specification of the original wheels and tires
installed on
Model Y, see Wheels and Tires on page 215.
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-
inflated (see Automatic Reset of TPMS Sensors on page
188).
NOTE: Installing winter tires with aggressive compound
and tread design may result in temporarily-reduced regenerative braking power. However, your vehicle is
designed to continuously recalibrate itself, and after changing tires it will increasingly restore regenerative
braking power after some moderate-torque straight-line accelerations. For most drivers this occurs after a short period of normal driving, but drivers who normally accelerate lightly may need to use slightly harder accelerations while the recalibration is in progress. Go to
Service > Wheel & Tire Configuration > Tires to select
winter tires and quicken this process.
WARNING: For your safety, use only tires and
wheels that match the original specification. Tires
that do not match the original specification can
affect the operation of the TPMS.
WARNING: Never exceed the speed rating of your
vehicle

WARNING: Only use Tesla-approved wheels when
installing or swapping wheels. Using non Tesla-
approved wheels can cause serious damage. Tesla
is not liable for damage caused by using wheels
not approved by Tesla.
Tire Configuration
After the tires on Model Y are rotated or replaced,
update your vehicle

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. Contact Tesla to have the fault repaired as soon as possible.
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

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.
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. 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

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

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
