I changed to the Goodyear Eagle F1 All Season. My reason was safety. No change in the ride. Tires are not the answer. Wish I could put the Audi A6 suspension on the Genesis.
To be fair, you put another high performance Good Year tire on it - I wouldn't expect that to have an impact on ride, TBH.
I would hope that going to a touring tire would make a difference. I understand many prefer the performance characteristics. Personally, I care primarily about ride comfort and noise.
