2015 Hyundai Elantra SE 1.8L with automatic transmission. Dealership says wheel bearings and suspension are good. It’s a constant hum noise that changes pitch and volume with vehicle speed. Noise doesn’t change with RPMs (watched tachometer for shifting gears). I suspect it may be my tires. My treads are still good but my tires are 5 years old. They were quiet when I bought them. I wonder if age and a level of wear could have caused them to generate more road noise or could the source be something I haven’t considered?

Reason: Edited thread title for clarification.
Tire cupping could do that. Run your hand on them and see if there is cupping. You can rotate the tires to see if the noise moves.
If you put the car in neutral and roll, is the noise still there? This, for the most part excludes the trans unless it is the final drive/diff.
Update. Took my car to my favorite tire shop to have noise checked while they do the 6 month rotation and check alignment. They verified the noise is the driver’s side front wheel bearing. Shop told me they don’t have a press. Contacted dealership and they have to place an order for bearing. Sticking to my usual roads. My commute to and from work is 9 miles with a 2 mile stretch of 55 mph and the rest of the roads are 45, 35, & 30 mph since they’re in the city. Staying off interstate and no long trips.
It's good they narrowed it down to the wheel bearing, hope that solves the noise issue.
I did have a set of Yokohama Avid Touring tires there were great for the first 20K, then began making a mild hum/rotational sound. I finally replaced them despite plenty of tread left. Hum gone with new Continental DWS tires.
Check rockauto; for a bit more you can get the wheel bearing and hub, no press needed.
Relatively DIY if you ask me. Done a few on heavier cars.
Autozone will loan you the axle sockets.

Those sound like some good tips, thanks for sharing :-)
What that run you? i recently replace a bearing on my Nissan, it was a pain job, cost my around $120, but I also had to buy a bearing puller, a tool I didn't have yet for another $100.

I used a hydraulic press puller I picked up from Harbor Freight, it was cake to use, far better then bolting something on to beating the crap out of it to get it off.
