Experience has nothing to do with it.
Either you are following the vehicle manufacture's instructions and recommendations on proper tire pressure or you are not.....
..............you, are not.
But you are gonna do what you are gonna do.....I'm not here to try to change your mind.
I'm just posting some correct info
i.e.
A tire's "maximum inflation pressure" may be different that the assigned tire pressure used to rate the tire's "maximum load." For example, while a P-metric sized standard load tire's maximum load is rated at 35 psi, many P-metric sized standard load performance and touring tires are designed to contain up to 44 psi (and are branded on their sidewalls accordingly). This additional range of inflation pressure (in this case, between 36 and 44 psi) has been provided to accommodate any unique handling, high speed and/or rolling resistance requirements determined by the tire and vehicle manufacturers. These unique tire pressures will be identified on the vehicle placard in the vehicle's owner's manual.

I was waiting for someone to jump in on this, because Rigormotor is wrong in a couple of ways. But each owner does what he/she THINKS is best to meet their own application.
Crazy Canuck speaks the truth as what pertains to the real automotive world ( and has been endorsed by every Owners manual, automotive magazines/publications, AAA, every KNOWLEDGEABLE technician). However, tire pressure should/can be adjusted for your vehicle weight load and use. Obviously, with increased weight, you would need to increase tire pressure.

I used to work with a guy that always ran his tires at max pressure. I gave it a try and did not notice any real difference in mileage. I did notice a difference in ride quality. Not worth it to me. I'll stick with the recommened settings

i drive lots and can tell you from experience that you will not notice really any better mpg from adding extra air pressure. And if you ask people who road race cars they definitely do not put in extra air pressure. I try to keep mine at the right pressure.

From coppell, a touch north west of dallas, to austin and a lil city driving and back to coppel got 25.6mpg at roughly 85mph. Much better than the evo7 we were gonna take lmfao. If i went 60 im sure woulda hit over the 28 im supposed to get. Took off a few mods n went back to stock tune just for the trip. :) im happy.

If it has tires...and those tires require air to stay inflated..then weight dictates just what those pressures will be..doesnt matter if its a wheel barrow or the space shuttle. Though..by varying pressures, certain characteristics can be realised. The weekend racer will lower it for traction...the hypermiler will raise it for less rolling resistance. The average Joe on the other hand, who chases groceries and kids should run the recommended pressures.so, is there an absolute? No. Driving style, wear requirements, traction needs, and weight ll have a say. The door sticker is for the average driver leading an average life , and who drives the car in an average manner. In other words...for those who dont know, o r want to know, the sticker numbers area safe bet...and it keeps the liability issue at bay.

Have to add...everything above and below recommended is a compromise...go high and ride quality, handling and wear are affected in some ways....go low and the same things occur...so it all depends on what you want , do I eat my french fries with ketchup..or malt vinegar? Or plain.....

The past month or so I haven't done any highway driving, with short stop and go trips and running the AC in the 90 degree heat and my mpg has really taken a hit. Maybe 24 mpg which is lots lower than the 30+mpg that I have been getting. I guess that is to be expected.
