Displaying Tire Pressures
Tire pressures display on the touchscreen in the cards 
area on the car status display, or by touching Controls > 
Service. The pressure of each tire displays in the 
visualization of your 
Model 3, in addition to what time 
your tire pressures were last measured. You can choose 
whether you want to display tire pressures using Bar or  PSI by touching 
Controls > Display > Tire Pressure. The 
touchscreen also displays your vehicle
Page 179 of 296
WARNING: Do not drive Model 3 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 3 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 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.
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 (1.5 
mm) or greater, whichever comes first.
Tire rotation is an essential part of tire maintenance. It helps maintain an even treadwear pattern which enhances the tire
Page 180 of 296
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 179). 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 214) equal or 
exceed those of the original 
specification.
For the specification of the original wheels and tires 
installed on 
Model 3, see Wheels and Tires on page 213.
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 Automatic Reset of TPMS Sensors on 
page 180).
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
