Michlin PR3 noise & vibration
Installed a set of PR3s on the o7 R...took a 200 mile ride yesterday and to my surprise I became aware of a rumble and a slight vibration above 70mph...I haven't started a trouble search yet..yes the tires were static balanced...inflated the first time without valve stems and then the valve stem installed and inflated to 36 &40 psi respectively...the thinking of two time inflation, inflate and check for proper seating on the rim and then fill to the desired pressure...any input would be appreciated.

Did a pro do the balancing with proper tools? If yes I'd go back to that shop and ask for re-balancing ...
If that doesn't help maybe the tires are defective?

I might be wrong but to my knowledge the PR3's develop the "singing" over time, not after 200miles. I think I have developed it my my set after some 12000km's, atleast when I turn I notice something going on, but for the first 6-8000km's or so I had no funny stuff going on what so ever.
