Big wheels vs standard wheels for beach wagons: Balloon tires are the only real answer

Standard plastic wheels sink instantly in soft sand, while wide balloon tires (10–12 inches, low pressure) float on top like a dune buggy. Look for “balloon” or “fat” tires, a steel frame, and a weight rating 50% above your load. A $150–200 wagon with the right wheels beats a $400 one with bad tires.
