This video explains why I chose to fix my wheelbarrow instead of throwing it away. (It has to do with conserving resources and reducing waste.)
Its inner chamber couldn’t be patched after too many punctures, and when I went to Home Depot and Lowe’s, I discovered I couldn’t buy a new inner chamber, because they’re no longer stocked. I’d have had to buy an entire new wheel and tire assembly, for almost the same price as a new wheelbarrow. What I did instead was to buy a new tubeless tire, which is made of solid rubber and never needs replacing, thus saving my wheelbarrow from the scrap heap and eliminating the need for new wheels in the future.
