215/50-17 is equal in diameter to 215/55-16. Donāt go over size. Max 225/50-17
And no matter what size you get, go for original Honda rims only. Non original ones are weak in quality and tend to break. Select an offset less than 45mm or wheels will move towards inside. Like Accord oem 17s have a 55 offset which makes the wheels go towards inside and that kind of looks odd. Some non original ones have an offset too less like 35mm and 8ā width which makes the wheels come out of the body too much. Again that looks odd
Your best bet would be to get oem 17s of Civic X like those which come on touring in USA. Price range is around 120k. Some friends have them on their cars and they look seriously great
