I didn't get much time to test today but I did recreate the Tokyo South Inner Gr4 race in a lobby and did a 6.5 lap stint (since pit road is at the hairpin). I'll note that I ran the Lexus with +5 brakes and during FIA, it was so squirrely, it literally spun on me while braking. There's some of that still there but the braking zone was a lot calmer during testing.
That said, I really hope the tire multipliers going forward are going down because the tire situation is not pretty. Before I go on, I'll note that my driving style has often given me a notable advantage with tire conservation.
Here's a screenshot of the Lexus tires right before I pitted during the FIA race.

This is the tire wear with the updated physics.

Lap time wise, it's not that far off from what I recall but the Lexus in the FIA race was a slip and slide adventure. Now, it's struggling not to hit the walls because the understeer kicks in almost by surprise and by then, even a full lift may not save it.
Some other cars I ran...
WRX: Good news, she made it. Bad news, only because it's hilariously slow.

RCZ: The last sliver was lost before I reached the hairpin and made the turn into the pits.

Cayman: My pace was not great but compared to it being all but invincible in the actual FIA race, it didn't feel as much.
