pressure

I just picked up a brand new 2024 ram 1500 Laramie with 5.7etorque my oil pressure after fully warming I’m seeing 22psi at idle, is this normal? Seems kind of low to me, would like to know what kind of idle oil pressure newer truckers are getting at idle.

I ordered wheels and tires from CustomWheelOffset with the tpms sensors installed. They don't sync with my truck though so just says unavailable and to service the system. Do I just need to keep driving now until they activate? Or, do I take it to someone to have them turned on?

Can anyone tell me the correct air pressure for my new tires? It may not have anything to do with it, but here is the factory sticker... BTW, what does the KN557954 in the lower right corner stand for?
