Only have 1600mi on the new Hankook Ion HT's on my Rivian with 21in wheels (we have very few options for 21's and these are new)- but I am impressed so far. The tires have lots of siping and still handle quite well. I expected them to be a little mushy like a winter tire after seeing them, but they are not. Wet roads perform very well. Haven't had any snow/winter yet to give feedback there, but I anticipate they will do well. Road noise is less than my previous Pirelli Scorpion AS oem tires by probably 30% if not more and road comfort is great. For EV owners - they appear to be less efficient than the oem - maybe 7% or so, which I kind of expected given they are heavier than the oem Pirelli. That 7% may feel like a lot, but for the cost differential, you make up more than that over the life of the tire. The Michelin Defenders that fit our 21's still cost about $100 more per tire as well. Unless you need that extra little bit of range, I think you can put up with a little sooner charging for the cost difference. In my current perspective, I would buy these again.
