2. If it’s a rear flat, shift onto the smallest rear cog. The first step in wheel removal is opening the brake, which makes it easier to get the wheel out. If you have side pull brakes, open by fully rotating the little lever on the brake upwards.
3. Open the quick release on the wheel with the flat and lift the bike to remove the wheel. To extract rear wheels, it helps to pull the derailleur back slightly to clear the axle parts as the wheel passes through. For the front tire, you’ll probably need to hold one side of the quick release and turn the other counterclockwise to create clearance to get past the wheel-retention tabs on the fork.
4. When you have the wheel removed from the bike, lay the bike on its side. You want the (right side) derailleur or drive train side facing up.
5. Remove the valve cap and nut Unscrew the tip and press down to let any remaining air out. Starting directly opposite the valve, wiggle a tire lever beneath the tire edge/bead and pry down to lift. If possible, hook the lever on a spoke, or hold it in place. Place another lever about 6 inches away from the first and pry here. Continue with your third lever until you can get one side of the tire off. Then reach inside and extract the tube. Pull the other side of the tire off the rim or pry it off with your levers.
6. It’s important to find whatever caused the flat and remove it. If you don’t, the sharp item might still be in the tire where it’ll just pop your new tube. To find it, remove your glove, and run it around inside the tire in both directions. If something sharp is still stuck in your tire, it’ll snag the glove. Remove it. Also, check inside the rim, too, to ensure the rim strip covers the nipples and anything else sharp.
7. If the tire has a large gash in it, simply place a dollar or Gu wrapper over it as you reinstall the tube. It’ll reinforce the tire at the hole and get you home. Replace the tire ASAP.
8. To start replacing the tire and new tube, Inflate the new tube just enough to round it out and remove any wrinkles, and place it inside the tire. Stand the wheel up (rest it against your shins) with the valve hole on top and hold the tire/tube over the wheel so that the valve is on top.
9. Place the valve partway into the hole and simultaneously push the part of the tire bead that’s at the valve and closest to your legs onto the rim. With both hands moving downward away from the valve, finish working the bottom tire bead (the one closest to your legs) onto the wheel all the way around.
10. With one bead in place, tuck the tube fully inside the tire and on top of the rim, which will cause the other bead to rest flush against the rim. Work this bead on, starting at the valve as you did with the first. You may have to push the valve into the tire to provide clearance for the bead. Once you’ve got it started, work your hands away from the valve pressing the bead onto the rim around the wheel.
11. With a few inches of bead left to pop onto the rim, the tire will resist. Let all the air out. Crouch and rest the wheel on your knee to have something to push against. Now, hold the bead in place with one hand and with your stronger hand, push down to roll the stubborn section onto the rim with the heel of your hand. But don’t try to pop it on all at once. Install an inch at a time, moving your hand along until you’ve fully installed the tire.
12. Place your pump on the valve and inflate the tire. To prevent valve damage, brace it by wrapping a finger behind a spoke so you’re pushing against your hand, not the valve. Inflate the tire until it’s just firm. At this point, inspect the tire to make sure it’s “seated,” which means that it’s sitting correctly on the rim. If the tube gets pinched, inflating further may blow the tire and tube off the rim! Make sure the bead of the tire is seated properly, once you are satisfied inflate tire to desired pressure. (Not exceeding manufactures max psi)
13. Reinstall wheel, reset brake and check to make sure the wheel is not rubbing on the brake. Now get back on the road!
