I am thinking about putting 17" on my HCH II. I have some sitting in the garage, but I need to get some new tires. The tire guys at the shop recommended 225/45/17. I looked it up on the tire calculator and that is the right size. I would like to upgrade them for something wider for handling.

What are some input on changing the wheels to 17"? Will it have a huge affect on mpg? The wheels that are going on there are OEM Honda wheels if that makes any difference. I am not sure about the weight though.
