Noise - Change tyres to Conti UC6 (New tires quieter, old tires noisy)
Bumpy - Try decrease your tyre pressure a bit and try it out
Downsize - As the last choice if needed

Yea iinm lar.. CC6 is 185/55/16, 195/50/16 is UC6, 205/45/16 is MC6

Yes city does come in 2 size tyre stock depend on which variant city you buy. 195/50/16 is aftermarket change, slightly decrease on sidewall height hence comfort reduce.

205/50/16 is the better option as sidewall height remain similar to stock 185/55/16, but 205/50/16 is recommended to put on a aftermarket rim with 6.5/7/7.5JJ rim whereas 195/50/16 can be put on stock rim hence save the rim changing process.

Sidewall height
185/55/16 (Stock) - 101.75 mm
195/50/16 (Current) - 97.50 mm

205/50/16 - 102.50mm
185/60/15 - 111.00 mm
195/55/15 - 107.25 mm


**Height bigger is better, more comfort

Well for sure going for 15", comfort will increase, your wallet will be less painful when changing tires. 195/55/15 more performance choice than 185/60/15 but then again if you focus on comfort then 185/60/15 better.
If you want to stay 16" then go 205/50/16, the sidewall is slightly similar to the stock height but wallet will be sakit sikit cause price range will be 200-400 per pcs depend on tire choice.
