What is the recommended tire pressure for a 2023 Tesla Model 3?

The 2023 Tesla Model 3 uses 45 PSI cold on the front axle and 45 PSI cold on the rear axle. These are the OEM specifications. Always measure tire pressure when the tires are cold — before driving or after sitting for at least 3 hours.

What tire size does the 2023 Tesla Model 3 use?

The standard (base trim) tire size for the 2023 Tesla Model 3 is 235/40R19. Higher trim levels and optional packages may use a different size — check the sticker inside your driver's door for the exact specification for your vehicle.

How do I convert the 2023 Tesla Model 3 tire pressure to bar?

45 PSI = 3.1 bar (front) and 45 PSI = 3.1 bar (rear). In kPa: 310 kPa front and 310 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures the same on the 2023 Tesla Model 3?

The 2023 Tesla Model 3 uses equal pressure front and rear (45 PSI). The vehicle's weight distribution and symmetric tire sizing mean both axles carry similar loads per tire.

What happens if the 2023 Tesla Model 3 tires are underinflated?

Running 5+ PSI low on the Tesla Model 3 causes uneven shoulder wear, increased rolling resistance (worse fuel economy), higher tire operating temperature, and reduced wet braking performance. In extreme cases, chronic underinflation can cause sidewall failure. Check pressure monthly and always after a large temperature swing.

What do the numbers in 235/40R19 mean on the 2023 Tesla Model 3?

On the 2023 Tesla Model 3, 235/40R19 breaks down as: 235 = section width in millimetres (9.25"), 40 = aspect ratio (the sidewall is 40% of the width, so 94 mm / 3.7" tall), R = radial construction, and 19 = the wheel diameter in inches.

What is the overall diameter of the 2023 Tesla Model 3 tires?

The 235/40R19 tire on the 2023 Tesla Model 3 has an overall diameter of about 26.4" (671 mm) and a rolling circumference of roughly 82.94", giving about 764 revolutions per mile. Fitting a tire with a different diameter will throw off your speedometer and odometer.

2023 Tesla Model 3 tire size: 235/40R19

The factory (base-trim) tire size for the 2023 Tesla Model 3 is 235/40R19. Here is what that size measures out to in the real world — useful when comparing replacement tires or checking whether a different size will fit.
