The inner tube is your air-cushion, and when inflated beneath the tyre it provides you with a comfortable, safe ride. Unless you’ve converted your bike to tubeless, your bike almost certainly has inner tubes.
Do all bicycle tires have inner tubes?
Most bicycles today have tires with tubes inside. The tube is made of rubber, has a valve in it for inflation, and is just the right size and shape to fit inside the tire. When you inflate most tires, you are actually pumping air into the tube inside the tire, which fills the tire.
How do I know if my bike has an inner tube?
You can examine the rim of your bicycle and look for the valve. If it goes into the tire itself, it is a tube tire. If you see that it goes into the rim, you have a tubeless tire.
How do I know what inner tube to buy?
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.
Do modern bikes have inner tubes?
The vast majority of bikes around the world use the standard tyre and inner tube combination we’re all familiar with, but when you start looking at high-performance and special-purpose bikes, you run into a few other types.

Can I put a tube in a tubeless bike tire?
Putting a tube in tubeless tires
The procedure for tubing tubeless tires is the same as for regular tires. … With the tubeless valve removed, you can place a tube in the rim in much the same way as a regular tire. You will most likely have more difficulty getting the tire bead back over the rim.
What causes slow leak in bike tires?
The tire may still go on and work fine for awhile. But, as you keep riding and topping off your tires as usual, the rim strip at that spot where it’s too close to the rim holes will eventually yield to the air pressure opening gaps and causing a slow leak (or even a fast one).

In contrast Schrader valves are more robust, universally used, and have an easily removable core.
Do bike tubes expire?
Heat and UV light are very bad for latex, so where the tubes were stored could be a big factor. Latex tubes deteriorate only if outside and exposed to light, sun, UV and extreme temperatures. There are tubulars that are 20 years old and still run great, so the tube has a long life when protected.
