Tire pressure question for 235/40/18 tires

I'm currently using Lowenhart BR5 rims mounted on Goodyear Eagle F1 GSD3 tires. My tire pressure is currently 36psi for all four tires. Is this PSI okay or should I be using more/less? I searched thru the archives and saw some people used more and some used less.

Also, when I'm not able to diligently check my tire pressure, I was thinking of getting the following tire pressure monitors to allow me to visually ensure that my tire pressures are okay. Are these accurate? I would buy four of these with a 36psi rating.

Is that tire size listed on the tire pressure sticker on your driver side B-pillar? If so, use the pressures recommended there.

No, unfortunately my tire size is not listed on the tire pressure sticker on the driver side B-pillar.

There's usually 2 choices on the sticker. One for <= 4 passengers and one for 5 passengers and/or max load capacity.

From what I've seen the recommended pressure for most tire sizes is 29 front, 33 rear for <= 4 passengers and 33 front 41 rear for max load capacity.

I run 29 front, 33 rear on both my BMW's. My E46 has 225/40-18 in front and 255/35-18 in back, my E39 has 235/45-17 all around.

Yeah, I did see the 225/40/18 size on the sticker, but it was a little confusing because I saw a circle symbol next to this size and then saw under the PSI column for the front tires the same circle symbol next to the 33psi (so I gathered from this that the recommended front tire pressure should be 33psi), however I did not see the circle symbol next to any of the recommended psi's under the PSI column for the rear tires.
