Movin, it' can't be the average... that would put BOTH in a slip situation (the big tire would slip forward and spin, the small one would drag and skip).

Tom the smaller tire will affect the engine RPM and the larger will freewheel to keep up (like you were making a turn all the time)

Talked to John about all this. We are going to run an experiment in a couple of weeks using his GPS to ascertain true speed. I have a tach in my Aspire to check RPM. We will drive in a straight line on the hwy at 60 MPH, with these front tire combinations:
Two small tires
Two tall tires
Left small and right tall
Left tall and right small.

That should nail this down for sure.

true, but i wonder, Tom, why the experiment? as in: is this for your own enlightenment, or is there an alterior motive behind this?

Yes.

a. just curious
b. was wondering if it was possible to use just one really large tire on front instead of two, to improve MPG. But that's probably not real practical anyway; two significantly different tires on front might lead to unpleasant handling characteristics.

May I ask the reason for all the mpg issues on here? I've seen many topics about trying to reduce your mpg? Just wondering why

Fixed it for ya.

Improving our MPG is just another aspect of what you can do with these cars, and it's just fun to explore. What I want, for instance, is two different cars: a high-HP sporty car (Festy) and a high-MPG "luxury" car (Aspire).

Hahaha ok, I just go for high power. Fuels not that expensive... You probably get it cheaper then I do!!
