A tire sized garden cart using inner tubes of this size seems to have arrived with a pinhole leak which I didn't find until I filled it to move a large amount of soil where the weight of the soil was causing the leak at the tires caused. The pipe becomes completely flat. This was noticed a few months after purchase as most applications up until then had not resulted in the tire's rigid sidewall looking flat. So I bought this replacement inner tube which fits perfectly and now I have 4 wheels that will keep the air in for more than a few days. This tube looks well built and I expect it will last me for many years. It came quickly and at a very reasonable price.
