I have a Radio Flyer Steel and Wood All-Terrain Wagon (model #32).
The tubes keep losing air but Harbor Freight doesn't have tubes with bent valves.
Radio Flyer's website has a "wheel kit" -- which includes the tire, wheel and inner-tube -- but it's very pricey.
The tires are 10" in diameter; the sidewalls say "4.10/3.50 - 4"; the axles are 1/2-inch in diameter; and the hubs are offset.
Where else can I buy tires, wheels and tubes to replace the factory ones?
