Thanks again for the reponse!
To answer your questions:
1) Noise location:
It is hard to tell exactly. Definitely sounds like the rear to me, and I think the rear right - but it is difficult.
2) Tire age:
Tires are Milestar MS932
11/2017
35,000 miles on the tires.
Pressure is good.
3) Tire pressure:
good
4) Tire wear:
The rear right looks more worn on the outside corner than others.
They actually all look a bit more worn than I thought they should, but the right rear was more noticeable.
5) Tracking:
No problem tracking - no having to fight the wheel.
Not every time - but sometimes when braking, particularly at higher speeds, I get some vibration in the brake pedal and wobbling on the wheel.
6) Noise change with steering:
Maybe - very hard to tell though.
I think it sounded a bit rougher turning left - but hard to say.
