No, they are specifically designed for wheels requiring 255x50, 255x55, 255x60, or 39-177 sizes. Always check your tire sidewall first.
These tubes use a standard Schrader valve, which is the same type found on most car tires and standard bicycles.
The bent valve design is used to provide clearance in strollers where the wheel hub or frame would otherwise block a straight valve stem.
This product includes a pack of two inner tubes.
If your tire is heavily worn, has exposed cords, or has large cuts, it is recommended to replace the tire along with the inner tube to prevent future flats.
Check for punctures caused by sharp debris left inside the tire casing or a pinched tube during reassembly.
Ensure the bent valve is angled outward for easier access with a standard pump head.
Deflate immediately. This indicates the tire bead is not seated correctly on the rim or the tube size is incompatible with your specific tire casing.
Installation typically requires tire levers to pry the tire bead away from the rim. Once the old tube is removed, inspect the rim tape to ensure it is covering the spoke holes, as exposed metal edges can puncture the new tube.
