I'm going to revive a dead thread instead of creating a new one!
I just bought a 1990 honda crx hf which has 155/80-13 and My current '98 civic has 175/70-14. The 1998's tires were bought by me and I know the history of them compared to this crx where I have NO idea. I want to switch the 14's to the crx but I have no idea what that is going to do to the speedometer reading, how the bigger wheel and tire is going to affect the MPG's, or what problems I'm going to run into.
