Roadsession: I plan on wearing out this set of tires and then changing back to the grand trek 35's like I had on my 430. What is weird is that under decel from 100 down to 75 mph not a sound, then a high pitched whine from there to about 69 mph, then nothing. On these Dunlops there are sipes cut laterally in the tread about every inch. I'm hoping that's it. Your statement reinforces that theroy. At any rate I have 7 yr 100,000 mile warranty, so I can wait if need be. Thanks for your input!
