FAQs
Will this fit my 12.5-inch pram wheel?
Yes, this tube is compatible with 12.5 x 2.50, 12.5 x 2.25, and 12 1/2 x 124 tire sizes.
Can I use a regular car pump to inflate this?
Yes, it uses a standard Schrader valve, which is the same type found on most car tires and bicycles.
What is the benefit of the bent valve?
The bent or angled valve makes it significantly easier to attach a pump head to wheels where the valve is recessed or located in a tight space.
How do I know if my tire is 57-203?
Check the sidewall of your existing tire; the size specification is usually embossed into the rubber.
Does this tube come with a tire?
No, this is an inner tube replacement only. It does not include the outer rubber tire.
Troubleshooting
Tube loses pressure immediately after installation
Check the interior of the tire casing for sharp objects like glass or thorns that may have caused the initial puncture and remain embedded.
Valve is difficult to reach with the pump
Ensure the bent valve is oriented correctly through the rim hole and use a flexible pump extension hose if the wheel hub is too narrow.
Tube keeps pinching during installation
Inflate the tube only slightly until it holds a round shape before inserting it into the tire, which helps prevent it from getting caught between the tire bead and the rim.

Setup, Compatibility & Care
To install the 57-203 inner tube, deflate the old tube completely and use tire levers to carefully pry one side of the tire off the rim. Remove the damaged tube, slightly inflate the new Petrolscooter tube to give it shape, and tuck it evenly inside the tire. Carefully seat the valve stem through the rim hole, tuck the remaining tube into the tire, and push the tire bead back onto the rim. Care should be taken not to pinch the tube with tire levers during installation. Periodically check tire pressure every few weeks, as small leaks or cold temperature changes can reduce air volume over time.
