## How to Find the Right Tire/Tube

1. Check the side of your existing tire — look for size like 26x1.95 or ETRTO 50-559
2. First number = wheel diameter (must match)
3. Second number = tire width (range usually compatible)
4. For ETRTO: width-mm × bead-diameter-mm (e.g., 50-559 = 50mm wide × 559mm rim)
5. Tubes fit a width range — one tube usually covers several tire widths
