Max pressure listed on the tire only tells you how far you could go if you wanted to.
There is no "best" pressure but what's best for you is likely to found from 35-45 psi.
See what handling suits you best in that range.
And don't worry about wear. Any non-optimum wear within that range will happen so slowly it is easily caught if you pay attention and rotate at regular schedules.
If you're wondering -- yes, one person could have good wear at 35psi and another at 45.
