Take the more common 12R22.5 tire as an example, its normal tire pressure should be around 9.3bar
295 tire pressure should be 9bar

Take the same domestic 295/80R22.5 tires as an example. In the cold state, their load axle tire pressure is 5.2bar, and the steering axle tire pressure is 7bar. Such a low tire pressure will definitely surprise everyone, but this is exactly what Their normality.
In addition, lower tire pressure has resulted in higher comfort and lower vehicle failure rate, so reducing tire pressure is not a bad thing.
