FAQs
What does the '57-203' size mean?
This is the ETRTO (European Tire and Rim Technical Organisation) standard size. '57' refers to the approximate width of the tire in millimeters, and '203' refers to the nominal diameter of the wheel rim in millimeters. It's crucial that your stroller's wheel matches this exact size.
What type of pump can I use with a Bent Valve (Schradar/Car Type)?
You can use any standard bicycle pump or an electric inflator that is designed for Schrader valves. These are the same valves found on most cars and many bicycles.
How do I know if my stroller uses this inner tube size?
Check the sidewall of your stroller's tire. The size designation (e.g., 57-203) is usually printed there. You can also consult your stroller's manual.
Can I use this inner tube with any stroller tire?
No, this inner tube is specifically designed for tires with the 57-203 size designation. Using it in a tire of a different size can lead to improper fit, poor performance, or damage.
What is the advantage of a bent valve?
A bent valve, especially a Schrader type, can be easier to access and inflate on wheels where space is limited, such as those on compact strollers or pushchairs. It angles the valve away from the spokes or frame.
Do I need to buy a new tire as well?
This product is for the inner tube only. You only need to replace the inner tube if the existing tire is in good condition. If the tire itself is worn, cracked, or damaged, you may need to replace both the tire and the inner tube.
Troubleshooting
Inner tube will not inflate
Ensure the valve cap is removed and the valve core is functional. Check that the tire bead is properly seated on the rim all the way around.
Inner tube loses air quickly after installation
Check for small punctures in the new tube. Ensure the tire is free of debris (glass, thorns) that could pierce the tube. Verify the tire is seated correctly on the rim.
Valve stem is difficult to access for pumping
This is inherent to bent valves. Try rotating the wheel or the valve itself slightly to find the best angle for your pump attachment. Ensure the pump head is fully engaged.
Tire feels wobbly or uneven after installation
The tire may not be seated evenly on the rim. Deflate the tire slightly, and carefully work the tire bead around the rim to ensure it sits flush, then reinflate.

Setup, Compatibility & Care
Compatibility:
- Ensure your stroller, pushchair, pram, or buggy wheel is explicitly marked with the size 57-203. Measure your existing tire's sidewall for this code.
- Verify that the valve type required is a Bent Valve (Schradar/Car Type). The valve stem is angled for easier access.
- This tube is designed for pneumatic tires; ensure your wheel rim is suitable for an inner tube setup.
Setup:
- Deflate the old inner tube completely.
- Carefully remove the tire from the wheel rim.
- Remove the old inner tube.
- Slightly inflate the new PetrolScooter inner tube to give it shape.
- Place the new inner tube inside the tire, ensuring the valve stem passes through the designated hole in the rim.
- Seat the tire back onto the rim, starting opposite the valve and working around.
- Ensure the valve stem is straight before fully seating the tire.
- Inflate the tire to the recommended pressure (usually found on the tire sidewall).
Care:
- Periodically check tire pressure and inflate as needed to maintain optimal performance and prevent premature wear.
- Inspect the tire for any embedded objects or cuts that could cause punctures.
- Store the stroller in a dry place to prevent rust and damage to components.
