I just found that the Vredestein Quatrac Pro+ all-season tire is now available in sizes that will fit the 21/22" wheel option on the Gravity. This tire wasn't introduced until July 2024, so I'm wondering whether Lucid didn't have it available to assess as an alternative to the Michelin Primacy AS tire that will come with that wheel option on the Gravity.
It is getting rave reviews and, frankly, I've never seen a tire test in which a tire so trounces others in the field on as many scores. Here's what Tire Rack has to say about it:

And the spider charts reflect this. In fact, I've never seen a spider chart is which one tire so clearly beat out others in the category of wet performance. And not only wet . . . the Vredestein beats the Michelin in every dry category except dry braking. (The Vredestein is the green line, and the Michelin Primacy is the dark gray line.)
