How do I choose a bike inner tube?

To choose the right inner tube for your bike, you must determine three things: the size of your wheel, the width of your tire at the type of valve that is compatible with your wheel rims.

Do bike tubes need to be exact size?

While your diameter measurement needs to be exact, your width measurement does not. Because inner tubes stretch, they typically come in a range of widths. For example, one of our most popular tubes is the 26 x 1.75-2.125” which means it fits a 26-inch diameter tire with a width in the range of 1.75 to 2.125 inches.

Does the width of a bike tube matter?

No, tubes and tires don’t need to match exactly. Tubes are made from butyl rubber which can stretch. Bike inner tubes will accommodate a limited range of sizes. Larger tubes may be more susceptible to getting pinched between the tire and rim.
