- Speed we would like to achieve is around 6-7 ft/sec.


This makes for a rather unique situation. Since you're using 6 wheels total, with different diameters, I'll need slightly more information.

Are all 6 wheels going to be in contact with the ground at the same time
or
will you be having the 12" wheels centered and "rock" between the 10" having only 4 in contact with the surface?
or
Another situation?

Are these wheels the pneumatic or hard rubber?

With this known, I'll be more than willing to chug numbers.
