Can I use a slightly bigger inner tube?
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. Having a slightly smaller or larger tube will be quite fine.
How do I know if my bike inner tube is too big?
If the tyre is a 700c x 23 or 25, then you should be OK. If it is anything larger than a 25, then you are pushing your luck a little, the tube is going to be very stretched inside that tyre.
Does bike tube have 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 a 26-inch tube in a 24 inch tire?
If a bike has clearance for 26”, it can obviously accept 24” wheels. However, the problem with rim brakes would still manifest because the braze-ons would be at the wrong place. If the bike uses disc brakes, this won’t be an issue. When the kid is large enough for a 26-inch bike, the original rims are installed.
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.
What inner tube size do I need?
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.

Why is my bike tube so big?
It isn’t normal, and will cause a problem. Tubes only expand when you put air in them, and will never get shorter. I’d try a different brand of tubes. Some (many) tubes are made to fit too wide a range of tire sizes and will tend to be a bit on the long side inside some tires.
How do I know my bike tube size?
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.
What is the difference between 24 and 26 inch bike?
What is the difference between a 24 inch bike and a 26 inch bike? 26 inch bikes have more tire clearance and a longer wheelbase than 24 inch bikes, which makes them easier to ride for taller riders. 26 inch frames are typically lighter and stiffer in order to compensate for the larger diameter tires they use.
Can you change tire size on a bike?
Bicycle wheels can handle a range of different widths, so it’s not absolutely necessary to replace your tires with one with the exact same width. In fact, there are often advantages to using a tire that is a little wider, as long as your bicycle has adequate clearance to handle the larger size.
Why does my inner tube seem too big?
Re: Why are inner tubes so much bigger than rims A new tube is (or should be) the length of the circumference of the mid height point of the tyre – and that diameter is greater than the diameter of the rim. hence it may appear too long.
