i would bend rims every day here if i went with anything bigger than stock. if you like driving alot, stick with 15s. otherwise youre gonna learn the hard way. i rode in a lowered civic with 17s and felt sick after 10 mins of bumps and jolts. im only dropped 1 inch on 15s and i still feel every little rock on the road. i cant imagine going worse than what i have now.

i have 18s with 235s and eibach sportlines, the ride isn't intolerable but I do blow about 2 tires a year with the potholes here in R.I. The look is worth it to me so I deal with it.

18s are fine. its all about how you drive. Dropping only an inch with 15s and feeling every bump or rock is not true. That's jsut being ****. You drive a civic, not a mercedes. So don't expect the ride to comfortable either way.

Go with 18s.

got 18s, its not bad at all! i'm running 215/35/18 because they came with the wheels but its not that bad. If you're a person who likes the way stock ride feels, its not for you, i don't mind it at all. They look better than 17s and feel the same. 16s and 15s are obviously the most comfortable.
