Noisy front end in 2014 E63…looking to diagnose.
I have a 14E63 sedan w/60 k miles. I’ve been noticing more tire noise, road noise in the front end as well as less nimble steering. Last winter I put on new kumho wintercraft tires with a db rating of 71-75 and it sounded like I was driving a truck. Then I put on my 1 year old Bridgestone Potenza Sports and the sound is much better but still there. I chalked the improvement up to a softer compound on the summers. I wondered if wheel bearings were going bad, stabilizer links, control arms? There’s no knocking or clicking over bumps. Wanted some advice before going to the mechanic.

2014 E63S; AMS 100 octane ECU dyno tune; EDOK TCU tune; BB intakes; sprintbooster
1 year old Bridgestones may be garbage based on the wear alone - forget that they're only 1 year old - what's the tread looking like? How many miles on them and how do you drive?
if they're shot I would get new Michelin ps5's summers first since you need new tires anyway (in that case) and then drive and re assess
there is a discussion here about issues with the steering rack causing slop with routine driving

Road noise - I wouldn't instinctively connect that with suspension components - what noise is it again- how would you describe it? What rpms... what speeds .. affected by turning or braking?
Wheel bearings, event mounts and propeller shaft hangar bearing have been documented as causing noise while driving at speed,
Also unclear if your steering perception is real or imagined and if real, then unclear if it's a connected issue or separate issue
and... tires and alignment could solve both the steering and road noise
any accidents recently or in its history?
audio clips?
