I don't think you know that wheel choice is the only thing that changed, and there is a very good probability that, although the wheels are not helping city driving, other things have also changed. Imperceptible changes in your throttling, wind patterns, routes, average daily temps, humidity, the number of stoplights you hit during the tank, minutes idling, and perhaps most importantly... the possibility of a creeping mechanical issue reducing economy but not yet setting off a CEL. I have dealt with that last one kinda often this year. Grrr.
But in the end, I agree the greater wheel weight will hurt city driving fuel economy and must be a contributor here.
Sorry
