I have noticed that my '16 GS350 F Sport with the 19" summer tires seems to need 3-4lbs of air every 3-4 weeks in each tire. If this was on one tire I would think I had a slow leak, but it is all 4. Are these wheels leaking air? By comparison, all things being equal, my other car seems to only go down about 0-1lb in the same period.

How may miles/how often are you driving? It seems normal after about a month of consistent driving that you would need to inflate your tires a few lbs.

3-4lbs, every 3-4 weeks...on all four tires.

How long has that been going on?

That is not normal.

How much are the outside temperatures fluctuating?

3-4psi a month is alot.

Has the ambient temperature changed in the past couple weeks? Are these stock tires? Maybe the tire installer skimped on the bead lube for the entire set?

I don't think that normal. Your car need 34 psi for each
read your senser when your car set. As soon you start driving the pressure gonna build up. I keep mine 33 in night time as soon I drive it at night or day I'll have 35 to 36 or more with hot weather

I have my stock Bridgestone tires on my 2016 F Sport set at 36-37 psi all around when it's cold in the morning and it usually goes up to about 40-41 psi in the afternoon right now in SoCal. As temperature drops so does the psi in our tires. I lose about 1-2 psi in about a month or so depending on how much I drive.

Yeah that is definitely not normal to be losing psi that quickly, I have driven mines every single day for exactly 3 months since ownership and my air pressure is still the same as the day I filled it.
