Gravity 75 mph Range

[Ron_Burgundy]

The Michelin Primacy Tour A/S that come on the 21/22 seem like a good compromise.

I get the argument for three season/summer tires, but it’s a pain to have two sets of wheels and swap them unless you really live in MN or something. The mid-Atlantic gets cold enough to where three seasons lose performance significantly, but there are probably less than 10 days a year where I’d really want winter tires. Even then, it’s not a must.

So, I make the year ‘round compromise of “all season”…

How cold does it get on 17? Summer tires have much higher grip than all-season in wet conditions as long as it's not too cold. High efficiency all-season tires are especially bad in wet conditions.
Here are some Tire Rack test results. The Hankook tires were much worse in wet conditions:

Those are different non SUV Hankooks

The point was that tires tuned for efficiency have significantly worse wet weather performance. And that summer tires have excellent wet weather traction as long as it's not too cold.
I doubt the Hankook iON evo AS SUV and Hankook evo iON AS have significantly different compounds. If there was some magic compound with excellent wet traction and efficiency they would have used it on both variants.

We could definitely continue guessing but the wvo SUV currently have good reviews on TireRack so I am hoping for a decent tire.

It’s used on the Korean EVs as well but then we don’t know if Lucid modifications made it better or worse for rain as they did make it narrower even vs same tire of same size for a different vehicle.

Never said it was a bad tire, in fact there may be no tire that is better than it in every way (i.e. it's Pareto optimal*)
But, I'm willing to bet the PZ5 has better traction in wet conditions in temperatures above 40F.

*Maybe this should be Lucid's slogan instead of "Compromise Nothing" which as an engineer I find offensive.

No argument that the smallest tire is the weakest for traction and PZ5 being the best.

I am happy to quantify the braking on smallest tire after my GT is delivered. One day.
