FAQ: How To Figure Out What Size Bike Tube You Need?

Will a 26 inch tube fit a 700c?

It’ ll work fine. It ‘could’ work if the 700c tube diameter is similar to the 26 inch. Some 700c are quite small, and some 26 are very large. Another concern is the size of the hole for the valve stem.

Will a 27.5 tube fit 700c?

However, tires that are close in bead diameter may use the same inner tube. For example, an inner tube for an ISO 630 tire (27-inch) will also fit an ISO 622 (700c) tire. The inner tube should also match the tire width, but, because inner tubes are elastic, one inner tube may fit a range of tire widths.

Will a 26 inch tube fit a 27 inch tire?

26″ tubes work perfectly well with 27.5″ wheels.

Does inner tube width 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.

Is 26 inch the same as 700c?

A 26 inch, or a 650c wheel is about 1 inch smaller (about 2 inches smaller with road slicks) in diameter than a 700c. Some people think that because 700c wheels are the ‘standard’ for road bikes, they must be better.

27-inch and 700C tires are close enough in size that the inner tubes are compatible; i.e. you can use a 27-inch inner tube in a 700C tire, and vice-versa. However, you can NOT use a 27-inch tire on a 700C wheel, and vice-versa.

Will a 27.5 tire fit a 26 rim?

Is the inner tube the same size as the tyre?

The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work, e.g. 26 x 1.95-2.125″, indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches.

Can I use a smaller diameter inner tube?

Yes, you can, as long as you don’t go more than one size smaller, or the differential is not too extreme. A 1.25 in a 1.5 is fine. A 1.25 in a 2.25 is likely to have issues with flats. Your LBS will have tubes.
