Enormous hand strength has nothing to do with receiving tires off or on by hand. What need is simple mechanical principle design for all clincher rims and tires? The design is old, and people hardly heard about it. The real makers of tire lever promote the tire and the rim makers to place hands only.
The general bicycle tire is known as clincher tire, and it is made with a bead to the inside edge of the tire. The beads adjust snugly to the wheel rim. Since the inner tube is inflated, pushing the tire bead against the bead seat of the rim.
The rim which has hook can hold the bead. The tire bead and the size of the rim bead must match well. There are lots of bead diameter standards, none of them is interchangeable.
Sometimes tire beads may be a tight fit with the rim. So it is very natural to use the tire lever to pry tire bead up as well as over rim sidewall. Please do not use a knife, sharp object, screwdriver that can damage the tire and the tube.
Totally threaded valve shafts have a locking nut after the rim. Lose and remove the locking nut prior to deflating.
- Deflate tire completely. Even the little amount of air in the tube makes the task difficult to get the tire off. To have a good result, press the downward the on the wheel at the time of depressing the valve.
- Press 1 bead of the tire to the rim center. The tire bead can be pressed tight towards the rim. If you press inwards, it may be loosened from the rim. Do the same for the other bead.
- Use a tire lever beneath the bead of the tire. Use the 2nd lever one to two from the 1st lever and after that draw both levers to the spokes to raise bead off the rim. Next, disengage one lever. Press forward it 2 inches to the rim and apply lever in the bead. Draw lever to raise the following section of the bed off the rim.
- Do again engaging the lever as long as the bead loosens. After that glide the lever to the rim beneath the bead.
- Begins opposite the valve and draw the inner tube from the tire. Raise valve from the valve hole and alter tube from the wheel.
- Take out the second bead from the rim that removes tire totally from the rim. Notice the rim and tire well; it would be best to remove all completely.
How to Change a Bike Tube
Disclaimer: All bikes are not the same. It is an instruction for a road bike. You have to follow the instruction of different bikes to remove the wheels from it.
- Screwdrivers / Bike Tyre Lever
- Air pump
- Replacement Innertube
Safety Info: Take necessary precaution to deal with moving part since you can get pinched.
If you feel any problem or being confused for any step, notice the photos given on the instruction. Captions have been added sometimes to make the idea completely clear.
At first, remove the wheel from the frame of the bike.
Toss the bike over since it remains on the seat as well as on the handlebars.
When the tire is to the front, loosen the bolts on both sides of the tire.
When you get the tire is to the back, you should remove the chain from the gearbox prior stepping forward for the next step.
- Use a wrench, and then unscrew the bolts from both sides of the tire
- Drag the chain off at the time of rotating the pedals
- Take wheel off bike frame
Take out the Inner Tube
- Remove the cap from the valve and take of the fastener
- Keep screwdriver or stick lever between the wheel and the tire
- Move around the wheel, and then take the border of the tire out of the rim. Note: You don’t take the tire off. Only the sides of the tire are necessary to be taken out.
- Take out the interior tube
- Examine the tire once again to see anything that may puncture the new interior tube.
Inserting the New Inner Tube
- Choose a right one inner tube which is correct in the type and size. You may get the accurate one or the internal tube you have removed just now.
- Firstly, be sure about the type and size of the tire.
- Place the new inner tube by keeping the valve into the rim first.
- Enter the remaining part of the inner tube inside the tire. If the interior tube in half in, you may inflate it a little bit to make the task easier.
- Keep in the tire again back into the wheel.
- At the time of turning the wheel, insert the tire backside to the rim. You must be sure that the position you tucked back in doesn’t come out.
- When the tire is going to nearly the way, use prying tool or screwdriver to obtain the final bit back on. You should have taken more precaution here as this is the most difficult step. If you press the tools in very far, you may have the risk of popping the new internal tube.
Inflating the New Inner Tube
- Use an air compressor and a pump to inflate the new tire
- Keep the cap and the fastener back on you have completed.
- Always keep the inner tube far from hot objects. Heat increases the pressure inside the tube and makes the tube explode.
- Before entering air into the inner tube or keeping it inside the tire, you can dust it with talcum powder.
- Don’t over-inflate since you can blow out the internal tube. Notice the suggested pressure printed on the tire wall.
- Be sure, the rims are drilled for Presta valves. You apply this tube rather than Schrader, they wouldn’t fit well.
- Don’t use oil or lube on the brake surface or brake. Also, avoid getting oil on tubes and tires. Oil can cause rubber to fester.
- Your bike has a quick release to the back wheel. You must be careful with the axle. Tackle it carefully. Keep it in a place where it may not get stood upon at the time of changing the gear. A little bend may mean you have to purchase a new axle.
- Tires and tubes lose longevity after using ten to fifteen years. If the tires and tubes are older than ten years, think more about replacing them.
- If you notice cracks to the fabric piles, you must replace the inner tube and the tire. If 2 tires are of the same age, you should better replace them both. As one change makes the other older. Moreover, there is the risk of a blowout.
- While refilling the tire after a puncture, check inside the tire carefully with your fingers. You may get nail, thorn or whatever it is in the tire. This can puncture a new tube as soon as you enter it. Be careful of it, and then enter a new tube.
- Before setting up the patched tube inside the tire, keep some air inside the tire. It can help you to check if there remains a second puncture for fixing.
- At the time of putting the tire back on or taking off, don’t puncture the inner tube.
- Always keep the inner tube far from the hot objects. Heat increases the pressure of the tube. It also makes the tube detonate.
