This innertube fits a number of different size tyres. Not all of the sizes this innertube fits will be printed on the innertube itself, as the space is limited. If your tyre or old innertube has 12.5 x 2.50 or 12.5 x 2.25 or 12 1/2 x 12 1/4 or 12.5x1.75 or 12.5x1.85 or 12.5x1.95 or 12.5x2.05 or 12.5x2.15 or 12.5x2.25 it will still fit.
