Inner Tube 255 x 50 Bent Valve

This inner tube is designed for tyre sizes 255x50, 255x55, 255x60, or 39-177.

It features a Schrader valve, which is the same type used on car tires. It also has a bent angle for potentially easier access during inflation.

You need this inner tube if your stroller, pushchair, pram, or buggy has a wheel tyre size matching one of the specified dimensions (255x50, 255x55, 255x60, or 39-177) and requires a bent Schrader valve.

No, this inner tube is only compatible with strollers and similar mobility devices that use the specific tyre sizes listed (255x50, 255x55, 255x60, or 39-177).

The inner diameter is 96 mm (3.78 inches) and the outer diameter is 190 mm (7.48 inches).

While not strictly required, tyre levers can be very helpful for safely removing and installing the tyre onto the rim. Basic hand strength is also needed.

The tyre size is typically printed on the sidewall of the tyre itself. It usually appears as a series of numbers and letters, such as '255x50'.

Ensure the Schrader valve is properly seated and not damaged. Check that the valve core is not clogged or stuck. Use a compatible pump.

Inspect the inner tube for punctures, especially around the valve stem. Check the tyre for any remaining sharp objects or debris that may have caused the initial puncture. Ensure the tyre is properly seated on the rim.

Ensure the inner tube is only slightly inflated, just enough to hold its shape. Double-check that the tyre size is compatible with the inner tube. Use tyre levers carefully if needed.
