I have a 2015 Model S with 104K total miles on it. RWD with 85KWH battery and staggered 21" Pilot SS tires on arachnid wheels. Recently I'm noticing a kind of faint "helicopter" like sound, especially when cruising at low speed. I took it in for service recently and the team just quickly looked it over and said everything seems fine but the noise persists. I have new rear tires that I got recently. Fronts still have some meat on them.
- Has anyone observed a similar noise with their vehicle?
- Has anyone had to replace their wheel bearings and if so when?
- Any tips on how to tell if the noise may be tire related, wheel bearing, or something else?
