Full details
This replacement inner tube set is designed for parents and caregivers who need a reliable, easy-to-install solution for strollers, prams, and buggies featuring 12.5-inch wheels.

FAQs
Will these fit a 12-inch wheel?
These tubes are designed specifically for 12.5-inch tires. While they may fit some 12-inch tires, compatibility depends on the specific tire profile.
Can I use a standard bicycle pump?
Yes, because these use a standard Schrader (car-type) valve, any standard bicycle or floor pump will work.
How many tubes are in the box?
This set includes two replacement inner tubes.
Why is the valve bent?
The bent valve is designed to make it easier to reach the valve stem in tight spaces where a straight valve would be blocked by spokes or the rim.
What is the Schrader valve?
It is the standard valve type found on almost all car and bicycle tires, recognizable by the central pin that depresses to release air.
Troubleshooting
Tube does not hold air after installation
Check for a 'pinch flat' where the tube was caught between the tire bead and the rim during assembly, or ensure the valve core is tightened securely.
Bulge visible on the tire surface
Deflate the tire and re-seat the tube; the tube is likely twisted or caught underneath the tire bead.
Pros and Cons
Pros
- Convenient two-pack set for complete maintenance
- Bent valve design simplifies inflation on small wheels
- Compatible with a wide range of common stroller tire sizes
- Uses standard Schrader valve for universal pump compatibility
Cons
- Requires manual removal of the wheel and tire
- Not suitable for foam-filled or solid non-pneumatic tires
- Bent valve may not suit every rim configuration
Setup, Compatibility & Care
To install these tubes, you must first remove the wheel from the stroller chassis using a wrench or quick-release lever. Deflate the old tube completely before using tire levers to pry the bead of the tire off the rim. Once the old tube is removed, inspect the inside of the tire casing for thorns, glass, or debris that might cause a repeat puncture.
Care instructions:
- Lightly inflate the new tube until it holds a round shape before inserting it into the tire to prevent twists.
- Ensure the bent valve is aligned correctly through the rim's valve hole.
- Inflate slowly, checking that the tire bead sits evenly on the rim edge.
- Avoid over-inflation; check your tire sidewall for the recommended PSI range.
