This guide is for owners of strollers, pushchairs, prams, and buggies with 8-inch wheels that require a 12.5-inch innertube when the tyre is fitted. The key benefit is restoring proper tyre inflation for a smooth ride. A potential caveat is ensuring your existing tyre or old innertube is compatible with this 12.4-inch size specification. This product is a replacement innertube designed for specific wheeled baby transport systems, featuring a Schrader (car-type) valve.

The innertube is designed for 8-inch wheels and fits a tyre with an approximate outer diameter of 12.5 inches. The inner diameter is around 7.72 inches, and the outer diameter is around 11.57 inches.
This innertube features a Schrader valve, which is the same type found on most cars and bicycles, making it easy to inflate with common pumps.
While designed for 8-inch wheels, compatibility depends on the specific tyre size. It's best to confirm that your tyre or old innertube measures approximately 12.4 inches as indicated in the product description.
Signs include the tyre being constantly flat, difficulty keeping it inflated, or feeling a significant loss of cushioning and stability when using the stroller.
You will typically need tyre levers to help remove and reseat the tyre, and a pump with a Schrader valve connection for inflation.
The recommended tyre pressure is usually printed on the sidewall of the tyre itself. If not visible, consult your stroller's user manual or manufacturer.
Ensure the Schrader valve cap is removed and the valve core is not stuck. Check that the valve stem is properly seated in the rim hole.
Check for leaks by submerging the inflated innertube in water. Inspect the tyre for punctures, check the valve stem for damage, and ensure the tyre bead is properly seated on the rim.
Deflate the tyre slightly and ensure the tyre bead is evenly seated all around the rim. Re-inflate carefully.
Compatibility Check: Before installation, verify that your stroller's tyre or old innertube has a 12.4-inch measurement and that your wheel rim is designed for an 8-inch tyre. The inner diameter is approximately 196 mm (7.72 inches) and the outer diameter is approximately 294 mm (11.57 inches).
