Query: Low Capacity - Cheap Tire

Bought these to replace a lost smaller 16" wheel. Hub can be knocked out for a 1" axle. The Wheels are fine, going slow over perfectly smooth terrain or with low weight loads. I had my wheels loaded (heavy) and they "potatoe Chipped" in that the wheel completely changed shape and the rubber came off. Easy enough to put back the rubber back on, but I'm looking for replacement.
