Charlie,
With that size tire and 3200# 20psig is probably about right, and I would think that they will wear right. The wear factor will probably be affected more by a heavy right foot coming off the stop lights.....

I run 18 psi in the rear of the Cobra, and 22 psi in the front.
Wear is even, but...for every three sets I replace on the rear, I've replaced only two sets on the front.
Dunno what the cause of that is...both front and rear travel the same distance.

I'm thinking the rears might get there a little sooner.
