I have never used falken tires until now, used mostly Michelin or Bridgestone. I find the ride has changed after putting 5k miles on. At 36psi on city streets, mainly Dallas area, the ride is very rough.
Thinking about changing to Michelin primacy 4+.
I truely love this vehicle but would like a little better ride quality.

 

There is lots of discussion about ride quality and attempting to improve it from the base stock level.
At least you are going about the better and really to only way to attempt to improve it.

You are in Dallas so your ambientes are very high this time of the year. So your tire will run a higher psi which effects the comfort, ride quality. Keep that in mind when doing your research to find a different tire.

 

I switched to Michelin Cross Climate 2, an excellent tire. Wait for the Mazda 4 for 3 tire deal. That said if you never drive in cold climates maybe a bit expensive but they work well in dry and rain.
