Signs you need to replace your bike tubes

A recurring flat tyre problem is probably the most obvious sign that you need to replace the tubes. You should also replace the tubes if the material gets punctured. To replace a defective tube, you’ll need to have some tools on hand such as tyre levers and workstands. You can easily replace your tubes in your workshop or even outside when you’re cycling on rough terrains. 

To replace the tubes, you should loosen the axle bolts first. From there, you can push the chain towards the sprocket - this way, you can remove the bike chains. Then, you need to use a tyre lever to remove the tyre from the rim. 

After detaching the tyre, you can access and remove the tube. Make sure to press the stem of the valve upwards before you pull out the worn or punctured tube. Then, carefully position the new tube. See to it that the valve stem lines up with the designed stem hole on the wheel's rim before you insert the rest of your bike tube.
