Description
Flotation tires spread floaters, spreaders and other heavy equipment over soft ground at low pressure, so the tube inside works constantly. This natural rubber flotation tube flexes with the wide casing and keeps holding air through that steady working.
This is the 42x25.00R20 and 48x25.00R20 tube, with a TR218A air/water valve mounted at the center. The large bore valve is rated to 150 PSI, works with liquid ballast, and the tube is made in the USA. Firestone recommends lubricating natural rubber tubes before mounting, then inflating, deflating and reinflating so the tube settles into the tire without folds.
This listing includes one inner tube.
