I also run my tires at 36 psi. Seems to be the best balance between handling and comfort.
That seems dangerously high and a good thing you checked it. Yeah, I see no issues with running in the middle of the recommendation 32 - 40. Honestly, I couldn't tell a difference between them being set at 37 and now being aired down to 33-34 but I guess some have better buttock detectors then I when it comes to tire pressure.

I am pretty sure we would have believed you without the pics.
I always do my own pressure. Now, go get some real tires on there...............

But I like pictures... I'm good with the stocker tires for now but certainly not a fan of them.

I run 34-35 cold so when they are warm, they show 37-38.
If those are the numbers when the tires were warm/hot then they are pretty right one.

32psi is very mushy. However, if you have air suspension, mushy tires + sport settings = pretty smooth ride

Tire pressure specifications are always Cold pressure ... what they become after running (warm-up) is immaterial given it is a moving target.

It's a fair point, but I checked the tire pressure in the morning after the vehicle sat all night. So I'm fairly certain the 37 reading wasn't inflated by driving temperature.

I purchased my GX460 last June and my tires were set at 36psi with the spare set at 55, too. I did pump my tires up to 40 but didn't mess with the spare.
