How do I know what size inner tube I need for my tires?

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.

Are all tire tubes the same?

The range for widths is usually between 1 and 3 inches. For example, a 26 x 1.75 size means the tire diameter is 26 inches and the tire width is 1.75 inches. 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.

Can you put a smaller tube in a bigger tire?

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.

Will a 26 inch tube fit a 700C tire?

This brings us around back to the same answer; they are the same diameter, but a 26-inch tire will fit onto a 700c rim but not the other way around because of the difference in rim thickness.

Will a 29 inch tube fit a 700C?

So a 29 inch MTB tube will have the same diameter as a 700c road wheel, while a 27.5 inch tube will be the same diameter as a 650b road wheel. You can also get 26 inch MTB tubes.

Will a 1.75 tube fit a 1.95 tire?

Answer: Yes. The 1.75 to 2.125 is the range for m small to large for tube that would ll fit. 1.9 to 2.125 fits in that range.

What happens if you use the wrong size inner tube?

If the inner tube is a lot larger than the tire, it will cause folds and wrinkles inside the tire, which may affect your ride. If you have a tube that is only a little bit larger, then it probably won’t make a difference. While larger tubes will weigh more, they will retain air better.

Will a 27 inch tube fit a 27.5 inch wheel?

27-5. 26″ tubes work perfectly well with 27.5″ wheels.

Do punctured bike tires need to be replaced?

If you’ve had a tube punctured as a result of a thorn poking through or a ‘pinch flat’ (which can happen when tubes are under-inflated), then the tire will probably still be perfectly usable. If the tube was damaged as a result of being slashed by broken glass or a blade, then the tire may well need to be replaced as well.

Do your inner tube and tire need to match exactly?

Perhaps you have an older bike or a bike with an unusual tire size. Or you have a bunch of inner tubes left over for a previous bike and wondering if they can fit your new bike. So does your inner tube and tire need to match exactly? No, tubes and tires don’t need to match exactly. Tubes are made from butyl rubber which can stretch.

Should I get a smaller or larger tube for my tires?

Larger tubes may be more susceptible to getting pinched between the tire and rim. It’s always best to try and match as close as you can, but there is some flexibility. Having a slightly smaller or larger tube will be quite fine.

What size tube should I get for my road bike?

Tube No. 17 can fit tire widths between 28 mm and 47 mm and that is a big advantage to the trade and simultaneously it vouches for the tube’s quality. Another reason is due to a lot of variation when it comes to manufacturer’s labeling.
