tire size there shouldnt be a problem if you get the right offset rims and not lowered to much.

 

ya i did check the tire size calculator just wanted to be sure also how do i check the offset ?

 

i put 18's on my 08 civic the second day i bought it and i am concerned about the slight rubbing i get. the last thing i want is to damage my arches or flares. its very minimal rubbing and only when i hit a decent bump (with only myself in the car that is) do i reallllllly need to switch to 17's? .
