I went from a 2013 300 base model to a 2020 300C. The ride is noticeably firmer probably because of the low profile tires (245/45/20). I do not want to give up the 20” wheels which look fantastic on the car, so what can I do to soften the ride? The 300C comes with Firestone Firehawk GT tires. Rated poorly by Tire Rack for ride comfort and noise, wet traction, and hydroplaning.
