Addendum: They don't hold air for long even when stored. Just bad tires. Big discount on tires from China. They were a bit thinner than the originals in my wagon, but they did the job. The originals also had bent metal valve stems, but since they were off center (as shown in the picture) I took a chance. They worked, but if it was a newer hand truck that is used regularly I would have spent an extra $3 on metal valve stems. Also, they claim to be 4 times thicker than other brands, but I seriously doubt it.
