Can Wheels Increase Tire Noise?

Jeepers, please chime in!
Yesterday I swapped out my stock Rubicon wheels that had 35x12.5 BFG KM2's on with 1.5" wheel spacers. Had the work done at Firestone tires, mount, high speed balance, tpms rebuilds, etc. So, it was a legit shop.

They replaced my Rubi wheels with 17x9 Pro Comp 8069-7973 wheels (17x9, 5x5, 4.75"; Backspacing -6mm Offset) However, when I drove off, it was loud. Louder than my stock rubi wheels on the same tires. I thought something was rubbing. So, I pulled off, checked out the wheel spacing, and nothing comes even close to rubbing. Based on my research, this wheel should have no issue with these tires, and visually, also no issues. The sound is just like the sound of tire threads on the ground, and gets a little louder with speed, so I'm pretty sure it is the thread on the road.

I checked the PSI, and they'd set it to 35, so I upped it to my usual 43, and that reduced the noise a bit. But, it's louder than when I brought it in.

So, has anyone experience a change in wheel changing the noise of the tires?

I can't see anything that could rub, and it drives perfect, no rub when turning, and plenty of space around all wheels. I'm 4.5" lifted, also. Freeway driving up to 80mph today, and no issues, no wobble, nothing. Just noise...

Thoughts? Deal with it, its just noise? or wheels shouldn't have changed the road noise levels?

our tires really dont make the noise,, its the air being forced out of the threads that make all the noise

43 psi, they'd set them to 35psi. More psi reduced noise some.

But still, only change was the rims, yet the tires are loud now.
