Note:

Before installation, check that the hoses are completely tight by placing them in water. If there are bubbles, they are already damaged.

Please check the position of the valve and make sure you install it in the correct direction.

Do not mount the tire with a pointed stick, crowbar, or sharp tool.

Do not inflate the hoses that are too heavily inflated without the cover ring.
