The Way to Change Bicycle Tires and Tubes
In my experience after reading some articles about bicycle tires and tubes, I think changing bicycle tires and tubes is very simple and easy, and we can do on our own. The tools that we need are Tire lever and tube. A few things that we need to know before changing bicycle tires and tubes , we need to wear eye protection because during installation bicycle tires and tubes it is possible for tube to pinch or explode. Make sure the valve stem stays in place when installing bicycle tires and tubes, because any unusual strain on the valve stem could cause a pinch or flat. It is better to turn the tire inside out when inspecting the tire from foreign objects.
The following is the simple way to change bicycle tires and tubes:
1) By loosening the quick release skewer , remove wheel from bicycle.
2) Remove air from bicycle tubes.
3) We need to use our tire lever and hook the outer edge of the bead.
4) Pull the tire lever around the bicycle rim, such that the tire bead pops out.
5) Remove bicycle tires and tubes, such that you remember its exact positioning on the bicycle rim. (This will aid in locating the cause of the puncture).
6) Slightly inflate the tube to approximately 15 psi and inspect for puncture location.
7) Once the puncture location is found, look in the same spot on the tire and the rim. Often times, a thorn or nail could have penetrated the tire and caused the puncture. It is also important to make sure that the rim tape is in position and in good shape. Often times, the spoke nipple will protrude and cause a puncture in the tube.
When you have determined what has caused the flat, make the appropriate repair.
9) Grab your new tube and inflate just enough to give the tube shape.
10) Place the slightly inflated tube inside of the bicycle tire.
11) Orient the tube and tire such that the valve stem is inserted into the rim first.
12) Slowly roll the bead over the rim with your thumbs. (Do not use tools! This could cause a pinch flat!).
13) Inflate the tube to approximately 20 psi and fondle the tube all the way around the rim to ensure it is seated properly.
14) Inflate tire to appropriate pressure. (i.e. 40 to 60 psi for most mountain bike tires).
