Got a flat? This high-quality Xiaomi M365 Inner Tube – Upgraded is the ideal option to get you back on the road.
The upgraded CST tyre (size = 9×2) is the same brand that originally comes with the Xiaomi M365/M365 Pro/M187 but twice as thick – protecting you from further flats.

These slide perfectly over the wheels and are the perfect replacement for a torn/punctured tyre.
Don’t bother in the false economy of cheap, throwaway replacement tyres – buy original to save time, energy and money.
They are more durable. And the valves are better so they can retain more pressure.
