seems low to me.

Well, it appears you are reading table correctly.
So the question is to what end do you want to change air pressure?
The table is for "minimum" pressure, but you can go higher if you want to lower rolling resistance (which in turn makes ride harsher), or to improve handling, etc...
On my van with larger tires I could run 40 PSI front and rear according to table, but instead run 55 PSI front and 60 PSI back. Much less than that seems low, plus makes the van drive a little too loose.
If it were me, I'd start at factory pressures on placard and then wouldn't drop it too much from that.
