Tubeless and a lot less pressure. I'm 185lbs and run 40mm at 30-40psi depending on the terrain, I'll run 45/50psi if I know it's going to be all pavement. I've gone as low as 28psi on really chunky gravel (sections that probably needed a mtb lol).
I would go 40-45mm (always good to leave room for mud/debris), def tubeless, and then play with pressure and see what works for you, prob start around 45psi and work your way down.
