I run mine at 32 psi cold, usually 35-36psi once they warm up. Anything higher and the steering feels too sensitive for my preference.

Running 37-38psi cold with max temp seen at 43F.

Not sure why some of you guys don't stick with the recommended 36psi. Over inflate or under inflate is not safe and will cause uneven wear.

I am running mine at 37 front 38 rear cold

Agreed. I run the stock Bridgestones (for now) at 36 PSI, which is the recommended pressure, or as close as I can get. I am actually somewhat particular about this and check on the pressure regularly.

Any benefit to running at 40?

When I picked my new '17 IS dash gauge showed 36 on all four and planning to keep it that way.

In almost all circumstances you should use the manufacturer's numbers as your guide. They are aware of the requirements of their wheels and tires. However, for people who have larger wheels and/or thinner profile tires, there is no value in an OEM tire pressure recommendation, if you are not using OEM recommended wheels and tire sizes. I'm running higher PSI to better protect my wheels from dips/cracks in the road.
