Size Selection Guide :
Always match the inner tube to your tire's sidewall markings (e.g., width/aspect ratio and rim size). Multi-fit tubes cover ±10-20mm width variations for flexibility; inflate slightly before measuring for a precise fit. Butyl rubber is standard for air retention in these sizes.
