Knox Model O average tire pressure is 30.472 psi. If it is tough for you can round it 30 psi for all 4 tires.
Overinflated tires are less of an issue. Knox Model O tires can easily withstand pressures that exceed those recommended for normal driving. However, consistently overinflated tires provide a less compliant ride and suffer more rapid wear in the center of the tread, which again means replacement will be necessary sooner than with properly inflated tires.

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