All noises went away with the new tires. 1500 miles or so and the re950's are nice, sticky wet and dry, quiet.
I probably had some damaged and/or very poor quality tires on prior. I could have sworn I heard some bearing noise, definitely tire noise, and another mystery noise that seemed very irregular and inconsistent. All gone. Or the gremlins are biding their time!:p
