Mg 18 average tire pressure is 29.798 psi. If it is tough for you can round it 30 psi for all 4 tires.
Mg 18 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.

Mg 18 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.
Mg 18 psi values are supported all kind of tire brands.
