Hi Chuck:
___I cannot directly comment on the HCH because I don’t know that many HCH pilots that have had to swap out their OEM’s so far. In the Insight community, those that have swapped due to wear or have swapped due to traction concerns in the winter usually see an immediate 5 mpg hit. I am speaking of a 5 mpg hit from those that are not hypermilers because a hypermiler won’t swap to a lesser FE tire under any circumstance in my experience. With that, you are looking at 55 - 65 mpg type Insight pilots noticing a 5 mpg hit with a simple tire swap the second they drive off from the Tire store of choice. This is a significant amount more then just 3% as you can tell.
___I have seen a much > then 3% increase in FE as tire pressures are increased from let us say 38 to 50 #’s in whatever I have driven which might help your HCH reach hypermiler status?
___I hope I provided you with some “Insight” (no pun intended  ) but those owning HCH’s will have to come to your aid with “the rest of the story” as Paul Harvey likes to say …
___Good Luck

Thanks for the information, Wayne. It is always useful to have some empirical data.
I don't think I (or my HCH) will ever achieve hypermiler status. I think I'm more of a mediocre-miler. However, I don't want to do things which will negatively impact my MPG, so knowing about the impact of other tire types is helpful.
My interest in new or different tires and/or rims is mostly for aesthetic reasons -- you know, wanting to individualize my automobile a bit (just like everybody else :-) ). I'm not talking about anything drastic like large rims or wide tires, just something giving the car a slightly different look.
I traded in my 2002 Honda Civic Si (the hatchback) and considered putting my aftermarket rims and tires from the Si onto the hybrid, but the dealer (wisely) talked me out of it. So now I'm just considering something like an LRR tire with a slightly different rim configuration.
Thanks again for the helpful advice!
