I had sentury tires on my daughter’s previous 04 Camry, and I agree they were quiet and performed perfect for a daily. They just didn’t last long.
If the noise from the falkens are gonna bother you, then I say replace them. You can always go back w sentury since they are less expensive and you know what to expect. I have an 05 Pontiac vibe and it’s not a quiet car. Had Sumitomo UHP all seasons and they were smooth and quiet. Now I have GY summer touring tires and they are just as smooth and quiet. The car is still loud so there’s a lot of wind, etc noise
