Stock sport rays on 2013+ PSI

Just want to know, apparantly tires lose around 1psi a month according to research. How much PSI do you lose ?

I filled up my tires on a cool evening to 39 rear and 37 front and within 2 weeks already rears are 36 / 36.5 and front 35 /35.5

In my opinion this maybe normal but not from other vehicles I have had. The weather is also warmer again here, so its not the cold temp showing a lower value. Remember I filled at cold.

I check my tires every time I get gas (~1/wk). It is not unusual to see a lost PSI. I just fill up with a compressor at home. Most of the time. I try to keep mine around 35-36 PSI. When we got our first cold spell of the Fall, my TPMS light came on during that week.

Yeah, I think I am aware of the @ cold and @ hot readings, a lot of folks have their tpms come on when it gets cooler her in the FL. It is my understanding that their tires were always relatively low on PSI since the heat gave them a false regular reading prior to the cold patch.

I actually did the opposite, filled up at ambient temp of approx 67 in the evening in the garage. Now the ambient in my garage is approx 74-80.
