Got up to almost 25k miles and after the ICCU update, had the dealership show me my tires were between 3/32 and 4/32 so knew it was time to buy tires. After researching all of the EV specific tires with foam inserts and, honestly, watching the Tire Rack video showing foam adds maybe a fraction of noise reduction it opened the window for many more tire selections out there. I have a EV6 Wind with 19" 235/55/19 tires.
Bottom Line: Very quiet, even tone in the low Hz. Impressive for a tire compound and design that does not have foam inside. Did not pull out the dB meter, but on par with the OEM Kumho HP71's. On smooth new roads they are practically inaudible. Very smooth over bumps, it absorbs more like a "grand touring" tire than an all-season ultra high performance tire. Have put about 1k miles on them already and impressed. Have not had any adverse weather to gauge, although, living in CO, I did notice they didn't score so well in snow; however, I'm in the city so 95% of what I drive on is just cold asphalt vs hardpack or deep snow.
Price: $870 including tax from TireRack. Had them shipped to my local DiscountTire (if you didn't know DiscountTire recently bought TireRack and they are merging) and that was $108 for install, so total $978. A pretty good savings vs the Hankook Ion EV's that would have been $1100 just for the tires. (I was very very close to getting the Hankook's).
All of the reviews: Mostly YouTube and a few articles and here are the Falken Azenis FK460's videos. They really did stack up against the other competition:
1. TireRack (They loved them) -
And of course pouring over personal reviews on TireRack, DiscountTire, SimpleTire, etc.
Very happy with them so far and will update after incliment weather here (heavy rain, snow, taking them skiing).
