Dear, plz dont waste money on tyre upgrade if your tyres are new.
Remember, overall tyre + rim radius of 17 inch tyres is same as overall tyre+rim radius of 16inch tyres.
It only adds to optics and psychological factor that you have 17 inch tyres.
PKDM civic 215/55 R16.
USDM civic 215/50 R17.
So if we see, if Rim size has increased with 17", the tyre height profile has decreased to 50.
Enjoy your stock tyre + rim, it will give you best handling and fuel economy. Moreover, PKDM civic's height has been increased by honda Atlas. So if you increase tyre+rim height, it will affect overall height of the PKDM civic which will further affect car's aerodynamics i.e. under body lift due to air passage and resulting drag.
