How To Pick the Correct Tire and Tube Size? - inSPORTline (2024)

Conversion table: Orientation table of compatible rim and tire widths:

Bike tires are made in different sizes, depending on the type and purpose of the bike. Tubes also need to be the right size for your bike. We’ve prepared a detailed guide to help you make sense of it.

Tire size is mainly given in inches, with the tires being made in diameters of 12, 14, 16, 18, 20, 22, 24, 26, 27.5, 28 and 29 inches.

You can also find the size given in millimetres – according to ETRTO (European Tire and Rim Technical Organisation) – and it is the most precise measurement. With bikes, you can find tire size 26x2,.1 (54-559), which denotes a tire withtire / rim inner diameter of 26 inches in (559 mm) and the width of 2.1 inch (54 mm).If given, it is advisable to follow this dimension in particular, as there are the same outer dimensions of the casing with a different inner diameter. For example, a 28 "tire may have an inside diameter of 622 mm or 635 mm. The tire may not fit in the rim.

Other accepted measure is the so called French standard that gives an approximate outer diameter and the width of the tire, i.e. 700x35C – approximate outer diameter (700 mm) and tire width (35 mm). The letter C stands for inner diameter, in this case 622 mm. The French standard does not apply to all available tires.

If you are picking out tires for your bike, find at least two dimensions (i.e. on the original tire) and use them to choose a new one. While doing so, keep in mind that the diameter always has to be the same as the current tire while the width can vary. However, you can only buy a tire that will fit within your bike frame and the size of its rims. The basic principle is that the width of the rim should always be smaller than the width of the tire. If the tire is too wide, however, it may not fit into the frame or the fork.

Tube sizes are similar, but there is usually a range of width given. Thanks to the flexibility of the tube, you can use one tube for more rim (tire) diameters.
