Return and Exchange Notice

The inner tube is a consumable item. Once inflated and stretched, it cannot be returned or exchanged. After receiving the inner tube, please first check if it is completely deflated (vacuumed during production). Deflation indicates a sealed and leak-free state. If necessary, you can slightly inflate it and then immerse it in water to check for any leaks or bubbles.

The inner tube must be installed in the outer tire before being inflated and stretched under high pressure. Otherwise, due to the uneven pressure from the high-pressure airflow on the tire wall, the inner tube will be stretched unevenly, resulting in inconsistent thickness. This is not a quality issue and does not affect usage, but it may cause confusion for beginners.

Once the inner tube is inflated and stretched, it cannot be returned or exchanged. Please check before loading the vehicle.
