I don't think you're gonna notice too much of a ride difference in the 185-55-14 vs. the 185-60-14. The Azenis were harsh because of the super stiff sidewalls. The Federals are pretty stiff, but it's been years since I have driven the Azenis so it's hard to compare. All I remember is I didn't like them. The Federals have a better pattern for rain evacuation, but the newer Azenis may have gotten better too. I got the 55 series, because I eventually want to lower it more, and I think it makes the wheels look a tad bigger than they really are. My suspension is moderately stiff also and I have a DOHC engine so it's a hair heavier too, which ads to the bumps, along with a short wheelbase. If you are going to daily drive it, I would probably go with 185-60-14 since there are tons of options and won't mess up your mileage.
