You have to think outside of the box.
That contraption started life as an electric scooter, I found two of those in the trash and robbed the wheels for my swap meet wagon. They are pneumatic, have a very smooth tread and good ball bearings so the rolling resistance is almost nothing:thumbsup:. If you have ever had to drag a V-8 engine block out of a swap meet with a regular radio flyer type wagon with hard wheels you know what I'm talking about:laugh:
It's kind of hard to see in the pic but this is the best i have in my albums for now....
