I have a 2007 civic coupe with 16" wheels and the standard low profile tires. I just pinched the sidewall and broke the rubber off the outside of the tire. What I want to check out is the idea of using smaller wheels and getting some tires with more rubber. possibly even slightly larger diameter tires too.

First question - how small can I get standard Honda steel wheels that will fit my car?

second - what is the bolt pattern of a 2007 civic coupe?

third - what is the standard tire diameter and how much larger can you go if you narrow the tread a little?
