100% accurate!

I also used to run my 5ES at 30 psi but hand on heart it is too low. 33 is OK.

The tires look they are under inflated, both sides were eaten much faster than the middle section, heavy steering…

I mean - as long as you don't drive at speeds well in excess of 60 mph - like 90 mph for sustained periods on low tire pressures.
Would cause flexing and rapid overheating of sidewalls for a possible blow out.

I've never had irregular shoulder wear at that pressure, but an ES is FWD and front heavy I suppose.
