I would like to have 200% (58-60 mpg) highway and at least 45 city. As it sits now, I got 42 miles per gallon on a ten mile city route to test the new tires I just put on.

Update February 6th - Tires were so bald it was dangerous, put steel wheels with 195/60/14 tires back on the front. Still running 195/60/15 aftermarket rims on the back. MPG in first gear has almost doubled when accelerating from stop. I would get about 4.9 MPG for the quick burst straight into fifth gear at 22 miles per hour. Now it is about 9.5 MPG for the same acceleration sprint to fifth gear.

During the wheel swap, I noticed both of my front shocks/struts/whatever are loose and have half an inch of play when not loaded with weight. I believe this is the reason the car is making a popping sound and the suspension shifts when making tight turns at full lock. Of course they won't tighten because I need a special tool to hold the strut while I turn the nut. This being loose is probably causing the abnormal wear on the tires. Sometimes it looks like I have camber and other times it doesn't. Time to fix it!
