How to remove clincher tire

The clincher tire, namely the common bicycle tire, is standard for bicycles. The wire bundle in the tire bead prevents the tire from expanding with the pressure and thus from jumping off the rim. Clincher is the international designation for this type of tire. So, how to remove a clincher tire? Let’s figure out together.

Step1 Deflate the tire completely
The first step is to deflate the tire completely, because even a small amount of air left in the tube will make it much more difficult to get the tire off. To achieve best results, press downwards on wheel when depressing the valve.

If your wheel is equipped with Presta valve, look first for any stem nut along the shaft. Loosen and remove this nut, then unthread the locknut at the tip of the valve stem.

For a Dunlop valve, unthread the cap only a few turns, and then pull outward on the tip.

Step2 Push the bead of tire towards the rim center
Push both sides of the tire toward the center of the rim to loosen the bead from against the rim sidewall.

Step3 Engage a tire lever under the bead of tire
Engage one tire lever anywhere on the rim except right at the valve. Pull back and lift the bead out of the rim. Take a second lever a few inches away and repeat. Continue the process until you feel the bead become loose enough to run the lever across the bead.

Step4 Remove tire and tube
Starting opposite the valve, pull inner tube from tire. Lift valve from valve hole and remove tube from wheel. Remove second bead from rim, which removes tire completely from rim. To fully inspect the tube and tire, it is best to remove both completely.

Step1 Reinflate the inner tube.
When possible, reinflate the inner tube to at least twice its normal width and look for leaks. By over-inflating the tube, you’re allowing any small pinholes in the tube to be detectable.

Step2 Find the leaks
Listen and feel for air escaping from the inner tube. Be sure to inspect the entire tube.

In some cases, immersing the inflated tube underwater will make the hole easier to find.

Step3 Mark the hole, and deflate the tube
The type of hole tells us about how the tube was punctured, and helps us prevent another flat. A small pin hole in the tube may indicate a puncture from a thorn or small wire. Feel carefully inside the tire body as you look for thorns, pieces of wire, glass or metal. Remove whatever you find. As a temporary fix, you can use the Park Tool TB-2 Tire Boot. Peel the backing and apply over the damaged area. However, change a new tube is the fastest and safest way to repair the tire.

Step1 Inflate the tube
Unfold the new inner tube4. Put enough air into the tube for it to hold its shape. Install the tube inside the tire. To make it’s easier to find the tire’s pressure recommendations when inflating, try to line up the valve with the recommendations on the tire.

Step2 Align the tire with the rim accordingly
Check for any arrows printed on the sidewall that indicates direction of wheel rotation. Align the tire with the rim accordingly. Engage the valve stem into the rim, making sure to align it so that it is not crooked.

Step3 Put the bead onto the rim
Work one bead at a time onto the rim. After one bead is installed, make sure the tube is stuffed inside the tire body. Beginning at the valve, push the other bead up and into the rim seat. Only when necessary, use tire levers to finish the bead installation. Work with care not to pinch the inner tube, or you may be repeating the entire process. Inspect the wheel to make sure the bead is uniformly seated and the inner tube is not poking out from underneath the tire.

Step4 Inflate the tire
Partially inflate the tire and check to make sure the bead is properly seated. It’s possible the tire bead can be seated either up or down too much. Inspect the bead seat line for irregularities. If the bead rises up in one spot, deflate the inner tube and push it back down to re-seat the bead. If the tire dips down in one spot, the bead needs to come up.

Once the bead is properly seated, continue to add full pressure.
