What is the recommended tire pressure for a 2023 Cadillac CT5?

The 2023 Cadillac CT5 uses 35 PSI cold on the front axle and 38 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 Cadillac CT5 use?

The standard (base trim) tire size for the 2023 Cadillac CT5 is 245/40R19. 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 Cadillac CT5 tire pressure to bar?

35 PSI = 2.4 bar (front) and 38 PSI = 2.6 bar (rear). In kPa: 241 kPa front and 262 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures different on the 2023 Cadillac CT5?

The 2023 Cadillac CT5 uses 35 PSI front and 38 PSI rear because the two axles carry different loads. The front axle carries roughly 53% of the vehicle's 1735 kg curb weight, requiring a slightly different pressure to maintain the correct contact patch at each corner.

What happens if the 2023 Cadillac CT5 tires are underinflated?

Running 5+ PSI low on the Cadillac CT5 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.
