I've put 1000 miles on my Insight and am still learning how to drive it for best mileage. If you got this mileage on a long road trip on the highway, then Something is Wrong. If this is around town, then it could be the tires plus not knowing the best techniques.
Or, it may be that Something is Wrong. On mine, the prior owner was getting this kind of long term mileage, and is not an aggressive driver. I've been slowly repairing the car and also not satisfied with the mileage (I have RE-92s reaching end of life). I recently fixed an exhaust leak and now I am getting an engine code for a lean mixture. I'm now suspecting low fuel rail pressure due to a possible leak in the fuel line in the tank (long story, and probably does not apply to you).
Honda Hybrid442 has told me that tires like your 185 60R14 are not going to give you that much a hit in mileage, especially after they break in. (Are your tires properly pressurized?)
I actually really like the 185 60R14 tire size. I once put some Yokohama 185 60R14 tires on a car that originally had 13" "bicycle wheels". I did not know until now that this car weighed only 150 pounds more than my Insight. It cornered like a dream with those tires and a modest shock-and-sway-bar upgrade, which arguably is "stock" for an Insight. So I'm really looking forward to similar tires on the Insight, as it seems that the added cost in reduced MPG is balanced by the substantially lower cost of these tires, with a boost in comfort as a benefit. So beware than an upgrade to RE-92 might disappoint?
I've been thinking of trying to find a local Insight hypermiler to drive around with me, basically call out my bad habits, correct my misperceptions, though @Natalya
has offered some good tips recently in the What Did You Do To Your Insight Today thread. Perhaps you can find a member in your area to ride with you, then get some new numbers in both highway and city regimens.
I was really surprised by the power the Insight can put out during acceleration if you take it to 4000-5000 RPM. So if you are driving the Insight for its fun factor (which I had no *idea* it had before I bought mine) then 45 MPG is not so bad.
