What is the recommended tire pressure for a 2019 RAM 2500?

The 2019 RAM 2500 uses 55 PSI cold on the front axle and 65 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 2019 RAM 2500 use?

The standard (base trim) tire size for the 2019 RAM 2500 is 265/70R17. 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 2019 RAM 2500 tire pressure to bar?

55 PSI = 3.8 bar (front) and 65 PSI = 4.5 bar (rear). In kPa: 379 kPa front and 448 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures different on the 2019 RAM 2500?

The 2019 RAM 2500 uses 55 PSI front and 65 PSI rear because the two axles carry different loads. The front axle carries roughly 54% of the vehicle's 2900 kg curb weight, requiring a slightly different pressure to maintain the correct contact patch at each corner.

What happens if the 2019 RAM 2500 tires are underinflated?

Running 5+ PSI low on the RAM 2500 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.
