Overinflating is having a greater PSI than the load calls for.

In an earler reply, you indicated your axle weight is 11,060 lbs, divide that by 4 equals 2765 lbs per tire. Using the chart I linked to previously your ST235/80R16 LR D tires should be inflated to somewhere around 58 to 60 PSI. Therefore at 65 PSI they are overinflated by over 5 pounds.
The best way to check tread wear is with a Tread Depth Gauge which can be purchased at any auto parts store.
