TL;DR
- Set your Tesla's tire pressure to the number on the label inside the driver's door pillar, not the number on the tire sidewall. On most Model 3 and Model Y wheels that is 42 psi. Cybertruck runs 50 psi at normal loads.
- Tesla says tires lose about 1 psi for every 10°F drop in temperature, so a warm garage reading can be 4 psi high by the next cold morning.
- Check pressures cold, after the car has sat for more than 3 hours, and never let air out of warm tires.
- The tire pressure light is a floor, not a target. Federal rules only require it to come on once a tire is 25 percent low, which is about 31.5 psi on a 42 psi tire.
The first cold snap of the year is when a lot of Tesla owners see the tire pressure warning for the first time. Nothing is broken. Cold air takes up less space, so the pressure drops overnight. This guide covers what pressure to run on each current model, how much winter takes off, and the two small pieces of gear that make checking it easy. It follows Tesla's own service pages for Model 3, Model Y and Cybertruck and was checked on November 5, 2026. Model S and Model X owners should use the label on their own door pillar.
What tire pressure should a Tesla run?
Use the tire and loading information label on the driver's side door pillar. Tesla's Model Y tire pressure page says to inflate to the pressures on that label even if they differ from the pressure printed on the tire itself. The sidewall number is the tire's maximum, not the right pressure for your car. The same page says the touchscreen shows the recommended cold pressures when you look at your tire pressures, so you can also read the target right on the screen.
Tesla's service manuals list the factory numbers it falls back on when the sticker is missing. These are the values Tesla publishes for current wheels, as of November 5, 2026.
| Model | Wheels | Cold pressure | Source |
|---|---|---|---|
| Model 3 | 18, 19 and 20 inch | 42 psi | Model 3 service manual |
| Model Y (2025 and later) | 18 and 19 inch | 42 psi | Model Y service manual |
| Cybertruck | 18 inch All Season, 20 inch All Season or All Terrain, normal load | 50 psi | Cybertruck tire pressure page |
| Cybertruck | 20 inch All Terrain at full rated load (GVWR) | 65 psi | Cybertruck tire pressure page |
Your own label still wins. If your car has aftermarket wheels or a different tire size, ask the tire shop for the right number. Tesla also says not to use the label pressures when towing, so check the towing section of your owner's manual if you pull a trailer.
How much does cold weather lower Tesla tire pressure?
About 1 psi for every 10°F. Tesla's Model Y page says tires lose one PSI for every 10°F (6°C) drop in outside temperature, and the Cybertruck page gives the same rule. NHTSA adds that the tire pressure light can come on during a cold morning and then go off once the tires warm up from driving. That is the pattern most owners see in November.
Here is a worked example. You set a Model Y to 42 psi in a 70°F garage, then park outside on a night that drops to 30°F. That is a 40 degree drop, so expect about 4 psi less, or roughly 38 psi in the morning. The car may not warn you at all, because 38 psi is still above the point where the law requires the light to come on. You are now driving about 4 psi under Tesla's number, and Tesla says underinflation reduces range and tread life.
Why the tire pressure light is not enough
The federal rule for tire pressure monitors, FMVSS No. 138, requires the warning to light within 20 minutes once a tire is 25 percent or more below the recommended cold pressure. On a 42 psi tire, 25 percent low is 31.5 psi. NHTSA says the same thing in plain terms: the system warns you only when a tire is significantly underinflated, and it does not replace monthly checks with a gauge.
So a quiet dashboard does not mean your tires are right. It means none of them is badly low. Our guide to what Tesla's tire pressure sensors actually monitor explains the sensors themselves and when one needs replacing.
One more wrinkle. Some Model Y Standard cars use indirect monitoring, which watches wheel speed instead of a sensor in each tire. Tesla's Model Y service manual says those cars need a calibration after you adjust pressure: go to Service, then Calibrate Tire Pressure, and tap Calibrate. Cars with sensors in the tires have no calibration step.
How to check Tesla tire pressure the right way
Tesla shows each tire's pressure under Controls, then Service, and in the Tesla app. You can switch between psi and bar under Controls, then Display, then Tire Pressure. Those readings are handy, but the timing matters more than the tool.
- Check cold. Tesla says to check after the car has been parked for more than 3 hours, and NHTSA also says to check when tires are cold, not driven for 3 hours.
- Do not let air out of warm tires. Tesla says about 1 mile of driving warms them up enough to change the reading, and warm tires read high.
- Add air to the label number using a gauge you trust, then drive above 15 mph for a short time so the car picks up the new readings and the warning clears.
- If the warning light flashes for one minute when you start the car, Tesla says that points to a fault in the monitoring system, not a low tire. Book service in the app.
The gear that makes winter checks easy
NHTSA suggests keeping a tire gauge in the car. A standalone gauge lets you check the cold reading in your driveway before the car has warmed anything up, and it helps you confirm what the screen says. Pick a digital or dial gauge that reads at least to 70 psi if you own a Cybertruck, since its loaded pressure is 65 psi.
A portable inflator saves a trip to a gas station air pump, which is often broken or coin-operated in winter. Look for one with an automatic shutoff, so you can set 42 psi and walk away. A cordless one is simplest. If you use a plug-in model, check its power draw first. Our guide to what the 12V socket will and will not run explains the limit. Every Tesla also skips the spare tire, so an inflator belongs in the same bag as the items in our roadside emergency list. You can browse picks that fit any model in the GetTesla shop.
Why bother over a few psi? NHTSA says only 19 percent of consumers properly inflate their tires, and that keeping them properly inflated adds an average of 4,700 miles to tire life. FuelEconomy.gov estimates that gas cars lose about 0.2 percent of their mileage for every 1 psi drop in average pressure. That figure is for gas cars, but Tesla's own page says the same direction holds for your range. To see how winter conditions add up for your car, try the range calculator, which lets you set temperature, speed and wheel size.
What to do
- Find the label on your driver's door pillar and note the cold pressure. Ignore the number on the tire.
- Check all four tires once a month and after any big temperature drop, first thing in the morning before driving.
- Keep a gauge and an inflator with automatic shutoff in the car, and top up to the label number when the reading is low.
- Before a winter trip, read our winter range guide and decide whether winter tires make sense where you live.
Frequently asked questions
Should I add extra air in winter?
Set the label pressure when the tires are cold. Doing that on a cold morning already gives you the right number for winter. Tesla does not tell owners to run above the label.
Why does my tire pressure light go off after I drive?
Driving warms the tires and raises the pressure. NHTSA says a light that comes on in the cold and goes off as you drive is a sign the tires are low on cold mornings. Add air when they are cold.
Can I trust the pressure on the Tesla screen?
It is useful for spotting a slow leak, but it changes as the tires warm. A gauge reading taken cold, before driving, is the one to set pressure by.
Is 42 psi right for every Model 3 and Model Y?
It is the number Tesla lists for current factory wheels, but always use your own door label. Older cars or different wheels can have a different value.
