If your ex feels squishy towing with 265/75r16 tires @55 psi you likely have other handeling related issues. 55psi in those tires will support the full gvwr of the Ex.
Seriously, if you arrived at 80psi by trial and error testing I would go back to 55psi and look for the real problem. My guess is you either have a worn out shock or simply need shocks with more compression and or rebound valving.
Also, since you mention E rating I assume you are not running a "P" or passenger vehicle tire but it is worth checking.

I use 60 front and 65 rear. I used to drop it when not towing but it's easier to just keep it there.

Tire pressure needed is dependent on a tires air volume and the load it needs to carry. The more volume a tire has the less pressure it needs to support the same load.

Looking at the stock 265/75r16 you see that @55 psi each tire will support 2625 lbs or 5250 pounds for both, which also happens to be the GAWR of the rear.
