. A 700×25 inner tube works in a 700X32 tire, but in a 700X45 could experience issues.

What happens if your inner tube is too big?

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

How do I know my bike tube size?

The best way to check what size inner tube you need is to

Can I put 20 inch wheels on 24 inch bike?

Can you put 24 inch tires on a 26 inch bicycle?

Your 26′′ tires sit on wheel rims, whose diameter is probably 559 mm.

Does inner tube width matter?


All inner tubes will come with a recommended range for tyre width

– for example 700 × 20–25 for traditional road tyres, 700 × 25–32 for wider road tyres. A narrower inner tube will balloon out to fill a tyre a few millimetres wider than its recommended width – but don’t take it too far or it might explode.

How much will an inner tube stretch?

If an inner tube is inflated outside of a tire, it will expand to

2 or 3 times its nominal size

, if it doesn’t pop first. Without being surrounded by a tire, an inner tube can’t withstand any significant air pressure.

Can you use a smaller bike tube?

The inner tube doesn’t have to match the tire size. That means

you can use a smaller or bigger tube, provided that it’s one size bigger or smaller

. Besides, there are advantages to using a bigger or smaller inner tube, as I’ll explain. Overall, however, there is nothing better than getting the inner tube size right.

What do bike tube sizes mean?
