Given there aren't any consumer reviews on here yet, I thought I'd give my preliminary view after running them maybe 200 miles.

I bought these off the back of an autobild comparison on the exact car I have (Model S, 19" alloys) where they outperformed the OEM and where about par with Pilot Sport 5 (which is what I was running before).

So far, I'm broadly in agreement with that comparison. Pros vs PS5 (or PS4 which I had before that, or Primacy 3 OEM which it came with)

- Quieter: without a shadow of doubt. Makes the car feel more refined.
- Efficiency: hard to be 100% sure yet, as driving style, weather, temperature etc affect the efficiency of EVs, but I do believe that there is an improvement in line with that mentioned in the autobild review (~5%)
- Price: I think it was about £730 for 4 tires vs £850 for PS5

Cons:
- Handling in dry is perhaps marginally worse, but I'm being quite picky on that. I'd say that they are ever so slightly greasier in corners, but it's marginal. It could even be due to the new compound not being worn enough.

TBC:
- Handling in wet
- Longevity

So far I'm not displeased. Will try to remember to come back in a few months time when I've driven 5-6k miles.

These are a replacement for Bridgestone Alenza 001 on my Nissan Ariya. The main issue with the Alenza being a lack of wet road grip. This has been resolved by the fitment of the Hankook Ion's which immediately have given me the wet traction I desired. They also feel better keyed into the road with more feedback and less understeer. The tires have more foam noise treatment than th Alenza's and appear marginally quieter.

This tire is being used on the Highland revision of the Tesla Model 3, where it's claimed this will bring additional range. I'll be monitoring efficiency and wear rates through the life of the tire. Tread depth starts at 6.8mm which is typical for EV specific tires.

After the preliminary review (200 miles - Tesla Model S, 11 Aug 2023) I thought I'd come back with extra thoughts several thousand miles in:

- The efficiency gains is accurate, these helped me get some of the lowest Wh/mile I've achieved in my Model S covering quite some miles in France over the summer, and then over the autumn. I've had my MS for 130k miles so have a good feel on what is achievable, and they did very well.
- They are definitely more refined from a noise perspective.

However - I do drive "enthusiastically" and having driven them a lot more now I can state confidently that these tires are greasier than the PS5s I had before. They are progressive in their loss of grip, so you have good feeling and there's not a moment of surprise where you suddenly lose your back-end, which obviously is a positive, and therefore I was not uncomfortable driving these, but in dry cornering they just don't hold up as well as I would want, and you feel the car sliding a little.

My wife also has a Model S with these tires on. She is not an aggressive driver but she also noticed that they are greasier too.

I've since sold my MS and have a X. When the summer tires on that need replacing I am very unlikely to buy these again (if they even do the size) - I just miss the grip too much. For my wife, we may stick with the Hankook's for the efficiency/noise as she is not an aggressive driver and the cost saving, and refinement/efficiency are probably worth the compromise on grip.
