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.
Well good to know I'm reading the chart correctly, there sure is a lot of room between the low and high end of the PSI range, not an exact science I guess.
Lower rolling resistance and better fuel mileage, handling all those are something to shoot for in my book.
My tire pressures according to the tire monitor after things had warmed up this morning were fronts 78psi rear 73 psi, I like the way it drives, so I guess I'm in the ball park.
Chance and all the others that contributed to my learning experience, I thank you !
