I was wondering if a 215/45/18 would fit my civic. I currently have 215/40/18 but girlfriend drives my car and three of my rims are bent and a other leaks air. So I want new rims but a bigger series of tire. I also dropped on sprint lowering springs I know they wont fit with those but I was thinking may a set of eibach sportlines or give me some suggetions.

Just get smaller rims with fatter tires if the roads are that bad. 215/45/17 or 205/55/16. Either that or you just had a very weak set of rims... Besides the guy in the apartment 2 doors down from me, who's Si has 4 smashed to hell Nakayamas on it, I've never heard of an entire set of rims getting bent up. A 215/45/18 tire is pretty big... considerably larger than stock... that may be a problem with any substantial drop...
Maybe find a place willing to test fit the tires for clearance before sending you out the door with them...
