This reminds me of my truck tire situation. My original tires were narrow (235mm) but had a sidewall rating of 80psi. I bought some all terrain tires because I was tired of getting stuck in wet grass, and decided to go fatter and taller (285mm). The new tires have a sidewall rating of only 50psi I believe.
Do wider tires not need such high pressure since the weight is distributed over a larger contact area?

Yeah, I normally drive with nothing weighing the bed down, and running over 40psi makes for a stiff and bumpy ride. I got used to it though. Tonight I'll find out what pressure I'm currently running and consider bumping it up.
