The new tires get similar mpg to the old ones.
Well, the new wheels look cool. And these numbers could mean that your MPG has actually improved, as you noted, the test itself is usefully suggestive but not conclusive. You might learn more as you drive around more. The extra weight will of course matter more in city driving, while the taller gearing won't help as much, no?

At minimum you know your new wheels are not costing anything too significant in mpg. And they look sharp.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
