What is the recommended tire pressure for a 2020 BMW 5 Series?

The 2020 BMW 5 Series uses 38 PSI cold on the front axle and 42 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 2020 BMW 5 Series use?

The standard (base trim) tire size for the 2020 BMW 5 Series is 245/45R18. 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 2020 BMW 5 Series tire pressure to bar?

38 PSI = 2.6 bar (front) and 42 PSI = 2.9 bar (rear). In kPa: 262 kPa front and 290 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures different on the 2020 BMW 5 Series?

The 2020 BMW 5 Series uses 38 PSI front and 42 PSI rear because the two axles carry different loads. The front axle carries roughly 51% of the vehicle's 1830 kg curb weight, requiring a slightly different pressure to maintain the correct contact patch at each corner.

What happens if the 2020 BMW 5 Series tires are underinflated?

Running 5+ PSI low on the BMW 5 Series 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.
