Wow y'all have some really nice trucks! Make my little old 2010 F150 FX2 feel so lonely

Any of you guys with 2WD trucks towing with 305/40R22's? If so what psi are you putting your tires at? I usually run lower psi for a smoother ride and better wear. They do fine pulling our little 19' Yamaha boat but wondering how they will do with the much heavier Max and tandem axle trailer.

Here's mine (disregard fuel door missing heh)...
