Before You Decide
Confirm the 26 inch wheel size, the 26 x 1.75 to 2.125 tire range, and the Schrader valve style before choosing an offer. The 2-pack format also matters if you only need one replacement tube.
Reading the Tire Size Marking
When checking the tire sidewall, compare the full size marking rather than relying on “26 inch” alone. In 47/57-559, the 559 identifies the rim diameter in millimeters, while 47/57 indicates the tire-width range. The marking helps cross-check the listed tube range against the tire already on the wheel.
