There is a reason why pressure monitoring system become mandatory on US sold cars quite few years ago.
Recommend pressure is always a balance between riding comfort, tread wear and rolling resistance (fuel consumption).
Could you handle the discomfort, the max psi allowed is the best for 2 other parameters. Radial tires will not change the shape with high inflation.
I had 2 blow ups on my vehicles and several more on equipment trailer.
When I blame vehicle blow ups to aging rubber, the low ride trailer had tire size where good quality tires are not available.
Cheap tires with heavy load don't need much.
