20" Inner Tubes
Used on the 1919-27 TT truck rear wheels and the 1928-31 AA truck wheels. We now offer our 20" inner tubes in two styles. A-1506-20 uses a TR150 Straight Rubber stem that is centered in the tube. A-1506-20-440 uses a TR440 Metal Stem. The stem is centered but has a right angle bend in the stem after it comes off the tube.
