FAQ

• Question: Why does the inner tube inflate unevenly?
• Answer: Newly manufactured inner tubes have not been inflated. If inflated excessively without the outer tire, the air may not distribute evenly inside the tire, causing uneven inflation. The correct method is to insert the inner tube into the outer tire, inflate one-third of the air, gently tap the outer tire around the rim, let the air distribute evenly, repeat the process with half the air, and finally inflate fully for durability.
• Question: What should I do if the inner tube has been inflated unevenly?
• Answer: If the inner tube has been inflated unevenly, release the air quickly, which will not affect the durability of the inner tube. Follow the above method to reinflate the tube evenly, ensuring its longevity.
