Installation Tips

• Lightly inflate the new tube before installation to give it shape and prevent twisting.
• Inspect the inside of the tire and rim for sharp objects or debris.
• Ensure the rim strip correctly covers all spoke nipples.
• Avoid using tools to lever the last section of the tire bead on, as this can pinch the tube.
• Confirm the valve stem is straight before inflating to the recommended tire pressure.
