There have been long and acrimonious debates about tire pressure. The problem is where is the line between safe and unsafe.
Your starting point in all this would be the vehicle tire placard, which is usually located on the driver's doorframe, but sometimes is in the glovebox, on the fuel filler door or in the trunk (boot). The tire placard will list the original tire size and the vehicle manufacturer's specification for that size.
The further you go from that value, the greater the risk. Risk of what? Traction issues, wear issues, rough ride, etc.
As a tire engineer, I don't recommend using more than 5 psi more than what is listed on the vehicle tire placard, but others have different opinions.
