Gray Model O average tire pressure is 30.278 psi. If it is tough for you can round it 30 psi for all 4 tires.
Gray Model O low tire pressures affect braking distances and provide less responsive steering and handling. This can be especially dangerous when an emergency stop or sudden evasive maneuver is needed to avoid a collision. In addition, low pressures allow tire sidewalls to flex excessively, which generates heat. While moderate heat simply accelerates tire tread wear; high heat can lead to loss of tread segments or even blowouts.

Gray Model O 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.
Gray Model O psi values are supported all kind of tire brands.
