Key Takeaways
- Tire Size Compatibility: Inner tubes must match the tire size for proper fit and performance. Always check the tire's size markings.
- Width Range: Inner tubes are often compatible with a range of widths. Ensure the inner tube falls within the width range specified for your tire.
- Material Choices: Inner tubes are typically made from butyl rubber or latex. Butyl is more common and cost-effective, while latex is lighter and offers lower rolling resistance.
- Valve Types: Common valve types include Schrader and Presta. Ensure you select an inner tube with the correct valve type for your rims.
- Patching and Repair: It's useful to carry a repair kit for punctured tubes, especially for long rides.
