Have you ever had to change a mountain bike tyre? Are you terrified that this might happen to you one day and you won’t know how to handle it? If that is the case, you have arrived at the right place. We have created this step by step guide to help you.
Removing & reinstalling a mountain bike tyre
– Remove the wheel of your bike by loosening the bolts on each side of the axle.
– Remove the valve cap (valve is the spot in which you can inflate your tire).
– Deflate the tire by pressing the small pin in the middle of the valve. You do not need to wait until your tire is completely deflated. When it becomes very soft, it serves our purpose.
Tip: You can easily deflate the tire by using one end of a tire iron. Do not hesitate to consult our stores that deal with tires and tubes and offer puncture repair service too.
Now begins the actual work. To remove your tire, you must first press its sides towards the rim center. Normally, the tire would just detach itself from the walls of the rim and move towards its center. – This is the time to use tire irons. Use them as levers to grab the inside of the tire and bring it over the rim.
Be careful not to puncture the tube. You can usually hook the curved end of your tire iron around a spook to keep the tire off the rim. Repeat the process again till another side of the tire is removed completely from the rim. Once the first half of the tire comes off the rails of the rim, you can remove the tube and after removing the tube, you can easily remove the whole tire by pulling with hands. If you also want to remove the ‘rim tape’, place a screwdriver under it via valve hole and lift it. The rim tape is generally elastic and gets easily removed.
Reinstalling a tire
If you have a rim tape (sort of rubber lining around the rim below the inner tube) you can go directly to the next step, else, stay here! If there is no rim tape, we need to install one.
The rim tape protects the bike from punctures: Tube is likely to puncture if it wears out on the rim. Little trick for easy installation: Line up the hole at the bottom of the rim tape with the valve hole of the rim and put your screwdriver inside the valve hole to keep the position of the tape fixed. The rim tape is slightly elastic in general but this way, you can easily install it.
Direction of Tire. Yes, most tires have a rolling direction. It is generally marked directly on the tire with a small front and rear arrow indicating the rolling directions for the front and rear tire respectively.
Installing the tire
You must first put one side of the tire on the rim. This can be done by hand. Once the right or left side is put on the rim, you can move to the next step. –Then inflate the tube slightly. Fit the valve through the hole in the rim before placing the whole tube into the tire. Now the remaining task is to put the second side of the tire on the rim! You can begin to do this by hand and if it seems too hard, you can use tire irons as levers to place the rest of the tire. (Be careful not to pinch the tube!) –In the end, make sure that the tire is correctly installed on the rim and then re-inflate it. Once the little valve caps are fixed, you’re done!
Different types of valves
To make best use of B’TWIN bike pumps, here are some useful tips for you.
Valve is the essential part of tube that enables inflation or deflation of the tire. It is important to distinguish in first place the type of valve fitted to your bike. There are two types of valves: –Valves that are usually fit in ATVs are ‘Schrader’ valves. –Valves that are fit in city or road bikes are ‘Presta’ valves. The valve type determines what type of bike pump nozzle will be used. For optimal inflation, make sure that the pump nozzle suits the valve.
For some pumps, B’TWIN has developed a system which allows you to inflate the two valve types with a single pump. In such cases, the pump nozzle is flexible and adapts to the tube that you want to inflate. You just have to fit the pump nozzle to the valve tightly in order to optimally inflate your wheel.
