Well....... A moderator changed this thread as I never said anything about sidewall????Your topic says "sidewall recommended" but the body of your message says "sticker recommended." Which one is it? These would be two very different values.
The sidewall value is not a recommendation. It's just a max pressure that the tire can safely handle. Just making sure we're all on the same page.
My question was about the sticker.
Changed title.
2 pounds over for 60 years. No issues yet.
Some of the 2000's SUV's used to have quite low recommended pressures, so I wouldn't below those, or if you've got a minivan and have it full of people and stuff often. Then the recommended might be the bare minimum. I think now more commonly is we have 5 passenger SUV's that have a huge amount of tire load capacity that will never be used, but the recommended pressure is set for fuel economy, so backing off the recommended pressures a bit is fine, in my unexpert opinion.

Typical commuter cars, door sticker usually says 28 sometimes 32. I put in 35 by default for no other reason than to not have to add air as often.
2021 Transit 250, factory LT225/R16C (Euro cargo van weight rating, allegedly equals 10 ply/LRE), unmodded, but basically loaded to near GVWR with me in it.

40psi.. maybe a touch less.
I watch the tread ware and adjust from there. 22 psi seems to be good for my Jeep to get even wear
I normally do what the door sticker says or go over by 1psi
+3 to +5psi, keeps the TPMS light away.
I remember that worked out great for Ford and Firestone on the Ford Explorer back in the '90's. As I remember it cost several people their life and Firestone recalled millions of tires. I've ran at least 35 PSI in everything I've owned in the past 40 or so years.
Toyota's TPMS threshold is 80% of door sticker, but mine are adjustable. Set the "correct" pressure to what I want then press the button to set it for 80% of that.
I go around 3 lbs over sticker pressure so when a cold snap hits I'm not under. I don't need tire drama on the coldest days of the year. I actually got a flat by checking my air pressure at -10'F, the valve core stuck, probably a piece of condensation-ice, and slowly flattened the tire. Never again, I'm not checking tires in the cold, that's a nice-day thing.

My TPMS light doesn't come on unless I'm 4psi below placard.
I just don’t want to fill tires when it’s cold, if I go a bit high when it’s in the 40’s-50’s they’ll be perfect when it’s in the 20’s!
Ya 26 psi was ridiculously low but that was over 20 years ago. How long do you want to hold automakers accountable? Should people no longer buy Jeeps because the old CJ from 40 yrs ago would break and tip over? Should we never buy a car made by GM because they wire tapped Ralph Nader's phone back in the 1960's?
The door sticker pressure is a compromise between comfort, handling, economy and safety. The last time I looked at the tires on the BMW, they said 54 psi max. I'll set them around 45-48 psi even if the sticker says 32-36.

closer to 30 years ago now, but the issue was still with the tires, regardless of Ford playing close to the margin on pressure.
