Deep section carbon wheels on a budget?

I run 80/85psi generally on the same tires and similar rims.

I’ve run them as low as 60 by accident but it felt like I was hitting bottom going over some railroad tracks.

When I do a group ride on the weekend, I go a little higher (90/95) for a little extra pothole / rim protection.

I’m about the same weight as you and really feel like 80 is the bare minimum to keep from bottoming out and to protect your rim.
