I run my 18's at about 29/36 lbs. They seem to wear more evenly. At the recommended (lower) pressure, they were getting the classic under-inflation wear pattern (it was subtle, but enough that it shortened the useful life of the tires by about 10%)

On long trips (I've done a couple 1,000 mile round trips to Oregon) I've run them as high as 32/38. I got 29.8 mpg on the way up, and 28.8 mpg on the way back with the AC on :-)

Your car looks great! (I'm pretty sure I've seen it around the Richmond district)
