How would your project be if you were to cut one of the sidewalls out - put a piece of cardboard on the bottom of the remaining sidewall - and then fill the "bucket" you have made? If you could find an "easy" way to cut the side wall out, it would make it easier to fill the tire.

Hi Tom,
I think that is an interesting idea, but my guess is that it is harder to do than packing dirt into an intact tire, or more people would use that method.

It works, but is much less stable. Drill a hole in the sidewall to start the cut. Then cut the side out with a sawzall. I used a tamper to pack the dirt. However, I was only comfortable going up 6-7 courses vs the 10-12 needed for a full size wall in a home.

@Bill
Or the reason could be structural :)... I just figured it was more work. I learned something today.

iirc - Ed Paschich, another NM architect working with tires, cuts the sidewall off & has a study showing little to no structural difference between cutting & not cutting.
