Description

Big radial tractor tires flex hard under drawbar load and run long hours at low pressure, and this natural rubber inner tube is made to move with them. Natural rubber stretches and recovers with the casing, so it rides with the tire instead of fighting it.

This is the 20.8R42 tube, which also fits 520/85R42, 620/70R42, 650/65R42 and 520/70R42, with a TR218A air/water valve set 4 7/8 in. off 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.
