Well I tried it! With all the hub bub about tire pressure on a non run flat, I dropped the pressure to 34psi. First thing I noticed pulling out onto the road was the back end moving around from uneven pavement causing the sidewalls to flex. Going over the same roads I travel, it just felt like the back end didn't want to ride steady from imperfections in the road causing the sidewalls to flex. Is it bad? I can't say. I just don't like that feel. To me it didn't feel as smooth at 34psi as it does at 40-42psi either. This tire was the flimsy walled General G-Max.
