Cooper Zeon 2XS set of 4. 235.60R18. They fit the stock wheel size perfectly, and because they're just a tiny hair bigger, it's possible I could see a slight MPG increase as well.

Next to source a set of these for cheap as well:

Need to get new lug nuts and center caps as well.

I'm feeling much better about the wheels now that I've found a much better tire.

Oil change and tire rotation in the morning, spending lots of money in the afternoon to try and make these happen in time for the next large gathering.
