Well it seems like a big dent on pocket but worth the money. It is way more comfy and quieter than Advan DB.
My civic has covered 30k kms on Continentals and still comfort level is as good as new and car has been driven a lot on bumpy and effed up roads of South Punjab, still tire tread is in very very good shape. I believe they will last another 50k easily.
If budget is tight. I'd say go for Yokohama Advan DB in 185/65/r15 size. Not more than that. City already has hard suspension and Advan DB serve the purpose well.
