New 2025 CX-5 with highway vibration problem; tires?

The vibration is a tire defect or tire balancing issue. The Toyo A36 were very smooth for me.
I sure hope so! As I told the tire shop guy, I just want the problem to go away. Searching back I did find posts of people saying it took more extensive repairs to the drivetrain or suspensions eg lower control arms. It isn't Always vibrating, which I expected if just tires (but I'm not a tire specialist). This rumble/vibration comes through the steering wheel, then goes away before repeating ... the cycle taking maybe 3-5s. Nothing noticeable driving around town. Very odd, and I'm not the first to experience it. Some who had bigger problems had to escalate it up to Mazda to get a fix ordered, and I'd rather not have to do that but I will. This is my first car - Mazda or otherwise - to have a manufacturer defect out the door :(
 
My new 2025 CX-5 (Toyo tires) is smooth on the highway. I did notice that there is a large amount of balancing weights inside the wheels.
 
I hope you like them - and that I will too! Good things being said here, at least.
And some advice.....they're asymmetrical, so make sure they're mounted correctly; inside/outside. Three of mine were installed incorrectly and had to have them redone. Funny how the installer didn't know that.
