What is the recommended tire pressure for a 2022 GMC Sierra 1500?

The 2022 GMC Sierra 1500 uses 35 PSI cold on the front axle and 35 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 2022 GMC Sierra 1500 use?

The standard (base trim) tire size for the 2022 GMC Sierra 1500 is 265/65R18. 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 2022 GMC Sierra 1500 tire pressure to bar?

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

Why are the front and rear tire pressures the same on the 2022 GMC Sierra 1500?

The 2022 GMC Sierra 1500 uses equal pressure front and rear (35 PSI). The vehicle's weight distribution and symmetric tire sizing mean both axles carry similar loads per tire.

What happens if the 2022 GMC Sierra 1500 tires are underinflated?

Running 5+ PSI low on the GMC Sierra 1500 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 265/65R18 mean on the 2022 GMC Sierra 1500?

On the 2022 GMC Sierra 1500, 265/65R18 breaks down as: 265 = section width in millimetres (10.43"), 65 = aspect ratio (the sidewall is 65% of the width, so 172.3 mm / 6.78" tall), R = radial construction, and 18 = the wheel diameter in inches.

What is the overall diameter of the 2022 GMC Sierra 1500 tires?

The 265/65R18 tire on the 2022 GMC Sierra 1500 has an overall diameter of about 31.56" (802 mm) and a rolling circumference of roughly 99.16", giving about 639 revolutions per mile. Fitting a tire with a different diameter will throw off your speedometer and odometer.
