50-60 mph excessive road noise

[Sfixxy]

Around 60mph I get a louder than normal road noise vibration not coming from the drive train. Brand new nitto invos with shelby 50th anniversary wheels. Once above 60 it completely goes away. All new bearings all the way around, only 30k on it.
Any thoughts?

My two thoughts are
Even though you have new tires I'd consider having them reballanced, maybe even have the beads broken and the tires turned a little and reseated on the rims. I've seen new tires that had to have that done to quiet them.
The other thing is to get under the car and make sure all of the plastic shields/air dams/deflectors are in place and tght / not missing connectors.

Was it present before the new rims, tires and bearings?

My thoughts exactly.

If car is good, and then you change something and car is bad, then you must first look at what you just changed.

I understand, I've had invo tires before on my Mustangs and they were always silky smooth. Is it possible that these brand new tires could be faulty and if so how do you prove it?

Absolutely possible. I've had this happen several times with different brands.

First step would be to return to the tire store where you bought them, and ask them for suggestions. You need them in your court. Probably the first step is to road force balance them, if they haven't already.

If the problem persists and you can show them what's going on, then they will (should) take it up with the manufacturer.

Tires and wheels are never exactly the same. That's why they are balanced once they are mounted. They can usually be randomly mounted and will balance out just fine. But sometimes they cannot be balanced completely. When this happens the first thing to try is to rotate the tire in relation to the wheel and try balancing again. That usually fixes it. But there are rare occasions when the tire has a manufacturing defect that prevents it from being able to be balanced.
As was said, your first step should be to go back to the shop that mounted & balanced the tires and discuss it with them. A good shop will know what to do and correct it.
