bob jane............No criticism here.
I'll also say, I guarantee I pay more for tires than you would in USA. There's the downunder freight tax, and shìtty conversion rate that slaughters us on anything imported.
I prefer a softer ride than you'll get at 55psi, but it's traded for this wear, and a more vague steering feel.
Difference in pressure can be felt in steering behaviour and bump absorption.
Different tires I've had have been comfortable and still responsive in low to mid 30s, or harsher, but more direct at low 40s psi.
Add more air if you're heavily loaded, towing, or doing a long highway trip.
