Okay guys, I'd like to report that I have now hit solidly in the 40's MPG wise... With this tire change I have now hit 41.35 MPG. This is running the tires mostly around 34 PSI. How much of a MPG improvement does pumping them up to say 40 or 44 PSI do? Would I see another 1 to 2 MPG? If so, I might try it and run my Illumina's on setting 1.

Oh BTW, I'm using the stock 2003 hub caps on the steel wheels. They seem pretty decent for aero, besides I waxed the crap out of them. I might eventually get the moon discs.
