Default Tires always leaking

I have a 22 c8, I kid you not....every other day I will go out and a tire, random side, will be down to 21 lbs. I don't think someone is jacking with me but air stability is my problem. Stock tires, still plenty of tread.
anyone experienced this?

Are you using the tire pressure on the screen or a hand held gauge?
Have you verified the pressure loss with a tire gauge?
My point, if you measured with a pressure gauge and all is good, then the display tire pressure may have a glitch.
If indeed an arbitrary tire is down 10 psi overnight, that certainly is strange.
Do you park it outside? If yes, them someone is definitely messing with you.
If its parked inside, and arbitrary different tires go down 10 psi overnight, I have no idea what to tell you bro!

You may have a bent wheel.

Just to be sure, perhaps a security camera. These are not too expensive, need no wiring, or subscription; that is buy it, put it up and no more cost. Both are solar wifi. Get alerts on your phone when breached as well as a recording.

They don't leak but if your car sits for a month the air pressure drops because cold air pressure drops but drive the car and they'll quickly go up.

An easy thing to check is the valve stem - make sure the core is screwed in tight. I had a tire leak this way.

verified by handheld pressure gage, I park outside, drive daily, only have 1 bent wheel but, ironically, it doesn't leak. I drive it daily and it will be ok for a couple of days and then bam....one wheel will be at 21 lbs.
I may get a camera setup just to see cuz this isn't funny...lol
I'm going to change all the cores for fun.
Thanks for all the input guys...I was just curious.

Yes, I had a loose valve stem. It should be tightened to 62 in/lb. Just try tightening it and see if the nut turns easily. Compare with other 3.

If not, you need to mix a little dish soap with water in a spray bottle.
My sister-in-law had a slow leak but hers took 2 months to loose 5 lbs. Turned out to be a tiny nail or a piece of wire. It took a lot of time spraying and looking for the small bubbles while spinning the tire on the car.

They gain 3-4 pounds when driving on a hot day. Bad valve stem? Bent wheel? Nail or slow leak? Neighborhood pranksters.
Have the tires ever been off these wheels? Are they the original rims. Did somebody screw up the bead when changing tires.

I think some here are misreading the original post...
He's losing air, not from the same tire, but from DIFFERENT tires, DIFFERENT sides, every other night he stated...
So the issue isn't a valve stem, or tire bead....
I feel someone's messing around... as its parked outside....

Random tires. different tire every day?
Loose valve stem seals or Schrader valves may be the easy answer.
Bent rims, bad tire seals, small punctures... a shop with a dunk tank could be low-cost step two.

But.... random act of "vandalism"... perhaps.
I recall seeing "locking" valve stem caps, which could be worth buying.
Blue Lock Tight... I would not recommend.
Good luck.

Well my tech skills suck. That didn't work. It showed a parrot pecking at the valve stem to enjoy the air blast...

I had a tire leak (not Corvette) only when the tire was in a certain position. I could go for weeks without losing air and then at other random times it would be down a few pounds. I finally found a small nail in the tread. My assumption was that it only leaked when the tire was flexed in a certain position while parked. However, this seems unlikely if there is more than one tire with this random leaking problem.

I had one wheel/tire that did this.....had to check it about once a week or so.....same one every time. finally took it to a tire shop, broke the bead.....cleaned the bead sealing surface on both sides.....lubed the tire like normal when putting tires on, it never leaked again.
