2016 auto. Going for a cruise - everythings normal. After 30-40 mi. I get this noise that you first notice as you come to a stop. It sounds like it could be something in the tire, but it's not. You slow down, it slows down, you speed up it speeds up. But you can only hear it it very slow speed. The longer you drive it, you can hear it at normal speed. No vibration or anything else strange, just noise. Any suggestions?

Two piece floating Brembo rotors clickedy click at low speeds and when manuvering in and out of the driveway.
Best I can describe is something between a clicking and rubbing. It's low freq. Again, it don't do it for about the first 30 mi. Then becomes noticeable as your stopping. Can't feel it, but can hear it (slight noise) in the car. Wife says she can't hear it outside as I roll by. The more you drive it gets to where you can hear it as your traveling 60 mph. It's definitely rotary, and worsens as things heat up. Crazy question - Can tires be expanding as they heat up and causing a rub? I've raised the front end, spun the tires, nothing loose, no noise, slight brake drag (as normal)

Tires wouldn’t expand anything noticeable. The pressure would slightly increase, hardly noticeable.
Perhaps you have some loose underbody plastic rubbing on a tire, driveshaft, ground. With more wind resistance at speed, could be pushing something that’s not seen/heard at lower speeds. I would start at front and all the way around look for signs of loose plastic that shows wear, including inside fender wells.

Thank you for your time and input. I just can't figure why it doesn't do it on short runs. It's like heat has something to do with it.
I actually get the same dang thing. It only happens at low speed, and seems to only be coming from my left side (can’t tell front or rear) wheel. It’s like a chirp. When I apply light brakes it still is there but heavy brake it’s not. I have removed and inspected both drivers side wheels, brakes, hubs, and can’t find what it is.
My car made the front rotor noise as the rotors were nearing the end of their life span and I was on my second set of brake pads (power stop). It was really only noticeable with windows down cruising 25-35 mph through neighborhood or canyon or by a block wall which would reflect/amplify the sound which sounded similar to a mild version of water running through a copper pipe through a wall is as close a description as I can equate to. What condition are your rotors in? Is there a protruding lip around the outside edge?
my rotors are in great condition, car has 22k on it and hasn’t been road raced. Another odd thing is it’s noticeable when turning right but not when turning left. Pads still have a ton of life on them and rotors don’t have any grooves or visible lines

Mine made a similar sound once. It was a little plastic plug that attaches to the fender lining rubbing on my front passenger side tire.
My WAG is one or more pads is dragging against the rotor. In my experience: cars before my Hellcat, my Hellcat, and more recently my Scat Pack and even my M-B cargo van; this can and does lead to faint intermittent low speed brake squeak or in some cases a rubbing noise.
My solution is to wash the brakes at a DIY car wash. No need to jam the wand nozzle down into the area of the pistons. The jet spray could tear the brake piston dust boots.
Just a thorough spray down on the soap setting followed by a through rinse then finish with a good rinsing using the no spot rinse setting.
Afterwards be sure you drive the car enough to use the brakes and hard enough to thoroughly dry the brake hardware. This includes the parking brake hardware "buried" in the rear hubs.
If you use plain water setting at first you can see how much dust come off the wheel/brake hardware. The water runs black.
(The dust build up on the dust boots interferes with the natural tendency of the piston seals to cause the piston to slightly retract when the brake pedal is released. This moves the pad just far enough away it no longer rubs against the rotor. If it doesn't retract... well I think you are hearing what this can mean.)
On a related note in my Hellcat shortly after I pulled out of a restaurant parking lot I heard a thumping from my Hellcat. Pulled into another handy parking lot and checked and didn't see anything.
Drove on. Got on the freeway and heard the noise again. It was clearly related to speed.
Took the next exit which was my exit and the short distance home. No other symptoms other than just the thumping noise.
Once home in the drive I parked car and got out and looked again. This time I spotted a length of apparently road tar that the right front tire had managed to pick up as I left the restaurant parking lot and drove though a bit of road work area with some repaving going on. I didn't drive over fresh paved or tarred road.
What I picked up apparently was a length of tar that resulted from a leaking valve and the tar tanker truck being moved which laid down a fraction of an inch diameter and who knows how long a strand of tar. The piece that was stuck to the tire -- in one of the circumferential grooves -- was approx. 18" long. It was stuck to the tire well enough that even I'm sure over 50mph it did not get thrown off. Never had that happen before.
Can I check that myself? What am I looking for?
Stock tires and wheels. Slow roll, sounds like it's up front. 60mph, maybe front to middle. It's hard to pinpoint.
