Description
Tall, narrow row-crop tires carry heavy loads on a slim footprint, and this natural rubber inner tube is made to move with them. Natural rubber stretches and recovers with the casing, so one tube covers a whole family of narrow sizes.
This is the 320/90R, 300/95R and 270/95R tube for 50, 52 and 54 in. rims, with a TR218A air/water valve set 2 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.
