Tire Pressure Issue?
Can someone help me out? ive had this werid tire pressure issue for a few days now.. where it sits all night and it drops almost 10 psi.
I looked for nails etc cant find anything so what could be the cause of this?
It seems fine to drive fine with no loss of air. only when it sits all night or all day when im at work. any ideas?

Mine fluctuates overnight but not that much maybe 3-4 psi. I am curious to hear about yours and what people have to say. From what I understand for mine it's the type of tire and the temperature fluctuation as well as the fact that the tires are inflated with air and not nitrogen.

Mine do too but this tire does it too much. i have PSS they go from 38-34 over night and back up in the day.. but this one goes from 38-27 over night. something is up with it.

Do you get the TPMS alert on your dash? Sounds like it's most likely an errant signal somewhere in your TPM system. First, there is no way for a tire to have 10 psi at one point and gain that much pressure at another point (unless you put air into it), second, you'd feel it as you drive if one of your tires was truly down to 10 psi. I'd take the car to your dealer to have them assess the TPM system.
Yeah im putting air in it every morning!! but its droping from 38- 27 over night. Yes my TPMS light is on every morning flashing.

This happened to me too. I went to Lexus twice and they couldn't find any leaks. The 3rd time they finally found out what it was.. It was a thin thin nail on the sidewall. It wasn't losing much air but every month I had the light go on, same tire. I thought it was odd. They patched the tire. The next week going to a basketball game that tire had another flat. It had to replaced. So go and check and make sure there isn't any leaks.

Have the tired dunked. Could be a bad bead seal or a defective valve stem. You always run a quality risk when you start going to very large 20" wheels and tires. Be safe
