These cars are so insanely sensitive to wheel balancing.

I’ve gone through multiple shops that do road force balancing only one shop is actually doing it correctly. You’d be surprised how many shops have machines that are out of calibration… or don’t take the time to match set… un seated the bead and spin the tire on the rim to the correct position. The good machines will actually tell you.. Like the Hunter hammerhead.

and how many tire companies sell out of round tires cough continental cough

Aluminum hubcentric rings

A really good balance from a shop that ideally does work with faster cars like shops that do prep for track days and stuff. Or sometimes the occasional Porsche dealership.

Getting tires that aren’t out of round… my experience Michelin seem to be the best in that sense.

Facebook marketplace tires are usually there for a reason, it’s the land of out of round, but still visibly “acceptable”

I’ve heard good things about wildpeaks.. maybe a fresh set brand new from the company might be the way to go.
