FAQs
Does this fit my 3.50-4 tyre?
Yes, this inner tube is designed to be compatible with 3.50-4, 350-4, and 3.50x4 tyre sizes.
Why is the valve bent?
The bent valve design is intended to make inflation easier on small 4-inch wheels where access to the valve stem is limited.
Can I use this on a wheel larger than 4 inches?
No, this tube is specifically sized for 4-inch wheels and will not fit larger rims correctly.
What should I do if the tyre feels loose on the rim?
Ensure you have the correct tyre size for your rim and that the tyre bead is fully seated on the rim shoulder.
Is this tube suitable for high-speed use?
This tube is designed for petrol scooters and small machinery, which are typically low-speed applications.
Troubleshooting
Inner tube will not hold air after installation
Check for 'pinch flats' caused by installation tools or ensure the valve core is fully tightened.
Tube punctured shortly after replacement
Inspect the inside of the tyre carcass for debris, thorns, or sharp wire that may have caused the initial failure.
Difficulty seating the tyre back onto the rim
Use a light coating of tyre mounting lubricant or soapy water on the tyre bead to help it slide over the rim edge.
Pros and Cons

- Bent valve design allows for easier access with standard pumps

Setup, Compatibility & Care
To install, deflate the old tube completely and use tyre levers to remove one side of the tyre from the rim. Carefully pull out the old tube, ensuring no debris remains inside the tyre casing. Inspect the inner surface of the tyre for thorns or sharp objects before inserting the new tube. Once seated, inflate partially to ensure the tube is evenly distributed. This tube is compatible with common 3.00-4 through 3.50-4 tyre designations. For care, regularly check your tyre pressure, as under-inflation is the leading cause of pinch flats and sidewall damage in small-diameter tyres.
