Gm Ev1 average tire pressure is 30.11 psi. If it is tough for you can round it 30 psi for all 4 tires.
A common situation in which you'd change Gm Ev1 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.

Gm Ev1 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.
Gm Ev1 psi values are supported all kind of tire brands.
