Remove the wheel from the frame

To change a rear tire, you first need to take the wheel off the bike. Flip the bike upside down so it rests on the handlebars and seat, or use a bike stand if you have one. This keeps your hands free and the wheel at a comfortable working height.

Locate the quick-release lever or axle nuts on the rear hub — the center of the wheel where it connects to the frame. If your bike has a quick-release lever, open it by flipping the lever away from the wheel. You may need to unscrew the opposite side slightly to loosen it enough to remove. If your bike has axle nuts instead, use a wrench to unscrew both nuts on either side of the hub.

Once the lever is open or the nuts are loose, pull the derailleur (the chain mechanism on the right side) backward and lift the wheel up and out of the frame. The chain will hang loose. Set the wheel on a clean surface so the tire does not roll away.

Key Takeaways

  • Remove the wheel by opening the quick-release lever or unscrewing the axle nuts, then pull the derailleur back and lift the wheel free of the frame.
  • Use tire levers to pry the old tire bead away from the rim, starting opposite the valve, and work your way around both sides.
  • Check the inside of the rim and tire for thorns, glass, or sharp objects before installing the new tire, because the same debris will puncture the new tube.
  • Seat the tire bead evenly in the rim all the way around before inflating, or the tire will bulge unevenly and may not hold air.
  • Reinstall the wheel by threading the axle back into the frame dropouts, then close the quick-release lever or tighten the axle nuts firmly.

Remove the tire and inner tube

Insert a tire lever — a flat plastic or metal tool — under the tire bead (the edge of the tire that sits in the rim). Start on the opposite side of the wheel from the valve stem. Pry the bead up and over the rim edge, then hook the lever to a spoke to hold it in place.

Move around the wheel, inserting a second lever a few inches away and repeating until one side of the tire is completely free of the rim. You do not need to remove the entire tire yet. Reach in and pull out the inner tube, starting at the valve. If the valve is threaded, unscrew the locknut first.

Once the tube is out, you can either remove the tire completely or leave it partially seated while you work. Leaving it partially on makes reinstalling easier because the tire stays in the correct orientation.

Inspect the rim and tire for damage

Before you install a new tube, run your fingers carefully along the inside surface of the rim. Feel for thorns, glass shards, sharp metal, or anything else that punctured the old tube. Even a tiny piece of debris will puncture the new tube in the same spot, and you will be back here in a few days.

Also inspect the inside of the tire itself, especially if the puncture was on the sidewall or if the tire is old. Look for cracks, splits, or embedded objects. If the tire is damaged beyond a small puncture, you will need to replace it along with the tube. If it looks sound, wipe the inside clean with a dry cloth.

Check the rim tape — the strip of rubber or plastic that covers the spoke holes. If it is torn or missing, the spoke holes will puncture the new tube. Rim tape is inexpensive and takes a few minutes to replace; it is worth doing now rather than repeating this job.

Install the new tube and tire

Inflate the new tube slightly — just enough so it holds its shape and is not completely flat. This makes it easier to seat evenly in the tire and prevents twisting. Unscrew the locknut on the valve stem if it has one.

Insert the valve stem through the rim hole first, then tuck the tube into the tire all the way around. Start at the valve and work your way around in both directions, making sure the tube sits flat and does not bunch up or twist.

Once the tube is seated, begin pushing the tire bead back into the rim. Start opposite the valve and work your way around both sides, using your hands rather than levers at first. When the tire becomes tight, use the levers again, but be careful not to pinch the tube. You will feel the tire snap into place as the bead seats fully.

Inflate the tire to the correct pressure

Before you inflate fully, spin the wheel and watch the tire bead. It should sit evenly in the rim all the way around, with no bulges or flat spots. If one section is sitting higher than the others, deflate slightly, adjust the tube, and try again. An unevenly seated tire will not hold air properly.

Once the bead is seated, inflate to the pressure marked on the tire sidewall. Most road bike tires use 80 to 130 PSI (pounds per square inch), while mountain bike and hybrid tires use 30 to 50 PSI. Check your tire sidewall for the exact range. Use a floor pump with a pressure gauge so you can see when you have reached the target.

After inflating, spin the wheel again and watch the tire. It should be round and centered in the rim. If it still looks uneven, let out a little air, adjust, and reinflate.

Reinstall the wheel on the frame

Flip the bike right-side up or keep it on the stand. Pull the derailleur back with your hand and guide the wheel axle into the frame dropouts — the slots where the wheel sits. The chain should fall naturally onto the smallest cog on the cassette (the gears on the rear hub).

If you have a quick-release lever, close it firmly. It should require real pressure to flip closed; if it closes too easily, open it and tighten the opposite side slightly, then try again. If you have axle nuts, thread them by hand first, then use a wrench to tighten both sides evenly. Tighten until the wheel does not move side to side, but do not overtighten.

Spin the wheel to make sure it does not rub on the brake pads or frame. If it does, the wheel may not be seated fully in the dropouts. Lift the wheel slightly and try again. Once the wheel spins freely, you are done.

Frequently Asked Questions

What if I cannot get the tire bead off the rim?

The bead may be stuck because the tire is old or the rim is dirty. Try using a tire lever with more mechanical advantage — a metal lever works better than plastic. You can also try loosening the valve stem to release air pressure, which reduces the tension holding the bead in place. Work slowly and do not force it, or you may bend the rim.

Can I patch the old tube instead of replacing it?

Yes, if the puncture is small and in the tube body (not the valve or sidewall). Patch kits are inexpensive and work well for emergency repairs. However, if you are already at home with tools, replacing the tube is faster and more reliable. Keep a patched tube as a spare for future rides.

How tight should the quick-release lever be?

The lever should require firm pressure to close — you should not be able to flip it with one finger. If it closes too easily, open it and turn the adjustment nut on the opposite side clockwise a quarter turn, then try again. The wheel should not move side to side when the lever is closed.

What pressure should I use if the tire says 50–65 PSI?

Start at the middle of the range (57 or 58 PSI in this example) and adjust based on how the bike feels. Higher pressure gives a faster, harder ride but less grip. Lower pressure gives more comfort and traction but uses more energy to pedal. You can experiment over a few rides to find what feels best.

Do I need to remove the cassette to change the tire?

No. The cassette (the stack of gears) stays on the wheel. You only need to pull the derailleur back to create space for the wheel to slide out. The cassette comes off only if you need to clean it deeply or replace it, which is a separate job.
