Why is the tube too long?

Asked by: Davin Edenfield

Why does bike tube seem too big?

If you installed the tube without inflating it first, just a tiny amount, then it hasn’t got the shape to sit in the tire completely, and it will appear to be too long. It isn’t, just add enough air to the tube to give it a little shape and try it again.

Can a bike tube stretch?

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. It’s always best to try and match as close as you can, but there is some flexibility.

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.

Can you put 25 tubes in a 28 tire?

Re: 20-25 tubes in 28mm tires??



It’s basically a no-no because as you pump up tyre the inner tube will stretch to fill the void of the wider tyre making it more likely to fail (or so the explanation went).

Can you use the wrong size 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.

How long do bicycle tubes last?

With proper maintenance and storage, bicycle inner tubes have been reported to last up to 15 years, and the shortest lifespan reported is less than 7 days. Common factors that determine the life span of a bike tube include storage, temperature, heat, light, exposure to elements and riding conditions.

Do lighter inner tubes make a difference?

‘ It stands to reason that a lighter tube is thinner and therefore more supple, which could result in an overall better ride experience – unless of course you experience an increase in punctures.

Can I put a bigger tube in a smaller tire?

How do I know what size inner tube to get?

The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.
