Gnome 3 average tire pressure is 29.69 psi. If it is tough for you can round it 30 psi for all 4 tires.
A common situation in which you'd change Gnome 3 sizes is when buying winter/snow tires. Retailers often recommend moving to a smaller wheel and using a tire with a taller sidewall, without increasing the overall tire diameter. This creates a longer footprint, also known as contact patch, where the tire connects to the ground. A longer contact patch can help snow traction.

Gnome 3 tire pressures should be checked at least once per month. Running on incorrect pressures will decrease fuel economy, it increases tyre wear and also degrades vehicle braking ability.
All-season tire pressure - 30 |
Winter tire pressure - 29.3 |
Summer tire pressure - 30 |
All-terrain tire pressure - 29.5 |
Be sure when checking the pressure that the tires are not too warm, which can happen after driving for a while, as this can affect the pressure reading.
Gnome 3 psi values are supported all kind of tire brands.
