What is the recommended tire pressure for a 2019 Kia Stinger?

The 2019 Kia Stinger 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 2019 Kia Stinger use?

The standard (base trim) tire size for the 2019 Kia Stinger is 255/35R19. 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 Kia Stinger 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 2019 Kia Stinger?

The 2019 Kia Stinger uses 35 PSI front and 38 PSI rear because the two axles carry different loads. The front axle carries roughly 52% 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 2019 Kia Stinger tires are underinflated?

Running 5+ PSI low on the Kia Stinger 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 255/35R19 mean on the 2019 Kia Stinger?

On the 2019 Kia Stinger, 255/35R19 breaks down as: 255 = section width in millimetres (10.04"), 35 = aspect ratio (the sidewall is 35% of the width, so 89.3 mm / 3.51" tall), R = radial construction, and 19 = the wheel diameter in inches.

What is the overall diameter of the 2019 Kia Stinger tires?

The 255/35R19 tire on the 2019 Kia Stinger has an overall diameter of about 26.03" (661 mm) and a rolling circumference of roughly 81.77", giving about 775 revolutions per mile. Fitting a tire with a different diameter will throw off your speedometer and odometer.
