The whining from the 20" Bridgestone Duelers on my 2008 4.8i is beyond reasonable. These tires have 23K miles but the noise started probably no later than 10K miles. About the same was true of the OEM Dunlops that made it to 16.5K miles (and might have lasted longer were it not for an upcoming major trip).

I have given up hope on making things better as the dealer says no problems with wheel bearings so I am searching to see if there is anything to do differently with my 2012 5.0i with 20" Bridgestone Duelers.

I have searched here and on other forums, talked to my service rep and the service manager. Sorry, but I get lost in these debates about excessive noise when discussing RTFs, staggered tires, rear-tires that are slanted in (//\\) ('negative rear camber'?), and so on.

I need to find a way to keep the 2012 as quiet as possible (like it is now) but my wife will not give up the OEMs and we need RTFs for two long trips a year plus I cannot rotate the tires so does 'unslanting' the rears lose much in performance or where should I be looking for solutions?
