Before You Start

What You Need

New Inner Tube: The correct size and valve type for your wheel and tyre.
Tyre Levers: Usually a set of two or three. Plastic levers are best to avoid damaging your wheel rim.
Pump: A floor pump (track pump) is easiest at home, while a mini-pump or CO2 inflator is essential for roadside repairs.
Optional: A puncture repair kit (if you plan to patch the old tube), a rag or gloves to keep your hands clean.

Safety, Timing, or Context Checks

Find a Safe Spot: If you're on a road or trail, move well away from traffic or other users. Give yourself space to work.
Check Your Brakes: Note how your brakes work. Rim brakes may need to be opened, and disc brakes require care to not squeeze the lever with the wheel out.
Gear Selection: Before removing the rear wheel, shift the chain onto the smallest cog (the outermost one). This makes removal and reinstallation much easier.

Check first: Ensure your new inner tube is the correct size for your tyre (e.g., 700x25-32c) and has the right valve type (Presta or Schrader) for your wheel's rim. Using the wrong size or valve will not work.

Step-by-Step Instructions

Step 1: Remove the Wheel from the Bike

First, you need to get the wheel off the bike. If it's the rear wheel, shift your chain onto the smallest cog at the back. This relaxes the chain and gives you clearance.

Next, release the brake. For rim brakes, there is usually a small lever on the brake caliper you can flip up to open them. For disc brakes, you don't need to do anything, but be careful not to squeeze the brake lever while the wheel is out. Finally, release the axle. Most modern bikes use a quick-release lever; open the lever, unscrew it a few turns, and the wheel should drop out. Some bikes have thru-axles (which you unscrew completely) or nuts that require a spanner.

Tip: If removing the rear wheel, gently pull the rear derailleur (the gear mechanism) backwards to guide the chain off the cassette as you lower the wheel.

Step 2: Fully Deflate the Tyre

Before you can remove the tyre, all the air must be out. The method depends on your valve type.

For a Presta valve (the thin type with a small nut on top), unscrew the nut, then press it down to release the air. You'll hear a loud hiss.
For a Schrader valve (the thicker, car-tyre type), use a small tool (like the end of a tyre lever or a key) to press down on the pin in the centre of the valve.

Press around the entire circumference of the tyre to make sure all the air is gone. This helps to break the seal between the tyre and the rim, making it easier to remove.

Step 3: Unseat the Tyre Bead from the Rim

The "bead" is the edge of the tyre that hooks under the rim. Over time, it can get stuck. With the tyre fully deflated, work your way around the wheel, pushing the edge of the tyre inwards, away from the rim, towards the centre. You might hear or feel a small pop as the bead releases from its seat. Do this for both sides of the tyre. This step is crucial for making the next one much, much easier.

Tip: If the bead is particularly stubborn, you can place the wheel on the ground, hold it steady with your feet, and use the heels of your hands to firmly push the tyre wall down and in.

Step 4: Use Tyre Levers to Remove One Side

Take your first tyre lever. Starting opposite the valve, slide the hooked end under the tyre bead and lever it up and over the edge of the rim. Now, hook the other end of the lever onto a spoke to hold it in place. Take your second lever and insert it about 10-15cm away from the first. Lever this section of the bead up and over the rim as well.

At this point, the tyre should be loose enough that you can slide the second lever along the rim, peeling the rest of the bead off as you go. You should now have one entire side of the tyre completely off the rim.

Warning: Never use a screwdriver or other sharp metal object as a lever. You will almost certainly damage your rim or puncture your new inner tube. Only use proper plastic tyre levers.

Step 5: Remove the Old Inner Tube and Inspect Everything

With one side of the tyre off, reach inside and pull out the old inner tube. Start at the valve; you may need to push it up from the outside of the rim to get it started.

This is the most important part for preventing another flat: find the cause of the puncture. Carefully run your fingers along the inside surface of the tyre. Be cautious, as there could be sharp glass, a thorn, or a piece of metal embedded in the rubber. Once you find it, remove it with pliers or the tip of a lever. Also, check the outside of the tyre for any damage and inspect the rim tape (the strip covering the spoke holes) to ensure it's intact and not exposing any sharp edges.

Step 6: Prepare and Install the New Inner Tube

Take your new inner tube and inflate it with your pump just enough to give it some shape – it should look like a floppy circle, not a fully inflated tube. This small amount of air helps prevent the tube from twisting or getting pinched under the tyre bead during installation.

Locate the valve hole on your rim. Push the valve of the new inner tube through the hole, and then gently tuck the rest of the tube up into the space inside the tyre, working your way around the entire wheel.

Tip: A small dusting of talcum powder on the new inner tube can help it slide into place more easily and reduce friction against the tyre, but this is an optional step.

Step 7: Reseat the Tyre Bead by Hand

Now you need to get the tyre bead back inside the rim. Do not use tyre levers for this if you can avoid it, as they can easily pinch and puncture your new tube. Starting at the opposite side of the wheel from the valve, use both thumbs to push the bead of the tyre back up and over the edge of the rim. Work your way around the wheel, pushing the bead in with both hands simultaneously, moving them towards the valve.

The last section will be the tightest. Push the valve stem up into the tyre to ensure the bead has room to sit in the deepest part of the rim channel. Then, try to roll the final section of tyre on using the palms of your hands.

Step 8: Check the Tyre is Seated Correctly

Before you inflate the tyre fully, you must perform a final check. Look at the line (the "witness line") moulded into the tyre's sidewall, just above the rim. Rotate the wheel and check that this line is an even distance from the edge of the rim all the way around, on both sides. If you see it dipping down into the rim at any point, the tyre is not seated correctly. If you inflate it like this, you'll have a bumpy ride and risk the tyre blowing off the rim.

If it's not seated, deflate the tyre slightly and push or massage the problem area until the bead pops into place. Sometimes, inflating to a higher pressure can help it snap into place, but be careful.

Step 9: Inflate the Tyre to the Correct Pressure

With the tyre correctly seated, you can now inflate it to the recommended pressure. Look on the sidewall of your tyre; you'll find a printed range, for example, "Inflate to 80-120 PSI" or "3.5-5.5 BAR". Using a pump with a pressure gauge is highly recommended. For road bikes, you'll be towards the higher end of the range, while mountain and hybrid bikes will be lower.

Proper inflation is key for preventing future punctures, especially "pinch flats" caused by hitting a pothole with an under-inflated tyre.

Tip: If you used a small hand pump on the road, your tyre might still be under-inflated. It's a good idea to top it up with a floor pump when you get home.

Step 10: Reinstall the Wheel and Check Brakes

It's time to put the wheel back on the bike. For a rear wheel, pull the derailleur back and guide the top section of the chain onto the smallest cassette cog as you lift the wheel into the dropouts. Ensure the axle is fully seated in the dropouts before tightening.

Tighten the quick-release lever or axle nut firmly. The quick-release lever should be tight enough that it leaves an imprint on your palm when you close it. Finally, don't forget to re-engage your brakes! If you have rim brakes, flip the release lever back down. For disc brakes, pump the brake lever a few times to reset the pistons. Spin the wheel to make sure it rotates freely without rubbing, and you're ready to ride.

Quick Reference

Situation	Use this	Why
The last bit of tyre is impossible to get on.	Push both tyre beads into the centre channel of the rim all the way around.	This creates maximum slack at the tight spot, making it easier to roll the final section on by hand.
Tyre has a bulge or dip after inflation.	Immediately deflate the tyre completely.	This is a sign the bead is not seated correctly. Deflating allows you to fix it and prevents the tyre from blowing off the rim.
You get another flat straight away.	Re-check the inside of the tyre for the original sharp object.	The most common cause of a repeat flat is failing to remove the tiny piece of glass or thorn that caused the first one.
The inner tube was punctured near the valve.	Check that the rim tape is properly covering the spoke holes.	A sharp edge from an uncovered spoke hole can easily cut the inner tube at its base.

Common Problems When You Change a Bike Tire

Pinch Flats or "Snake Bites"

A pinch flat happens when the inner tube gets caught between the tyre bead and the wheel rim during installation. When you inflate the tyre, the pressure can rupture the tube, often creating two small, parallel holes that look like a snakebite. The best way to avoid this is to add a small amount of air to the new tube before installing it to give it shape, and to use your hands, not tyre levers, to refit the tyre. After refitting, push the tyre wall away from the rim and check all the way around to ensure no part of the tube is visible.

The Tyre Won't Seat Evenly

Sometimes, a section of the tyre bead stubbornly stays in the deep central channel of the rim instead of popping up into place. This creates a low spot or dip in the inflated tyre. To fix this, you can try over-inflating the tyre slightly (but not exceeding the maximum PSI rating) to force it out. A more reliable method is to deflate the tyre, spray some soapy water on the bead and rim in the problem area, and then re-inflate. The soap acts as a lubricant, helping the bead slide into its correct position.

The Tyre is Extremely Tight to Get On or Off

Some tyre and rim combinations are notoriously tight. The key is to use the geometry of the rim to your advantage. The rim's diameter is smallest in the centre channel (the 'well'). When removing the tyre, once you have one section levered off, push the bead of the opposite side of the tyre into this central channel. This will create slack, making it easier to remove the rest. The same principle applies when installing it: make sure the bead is sitting in the well all the way around to give you the slack you need to pop the final, tight section on.

Advanced Tips for Changing a Bike Tire

Using a Tyre Boot for Emergencies

If the object that caused your puncture also created a large gash or hole in your tyre, a new inner tube will simply bulge out through the hole and puncture again. For a roadside fix, you can create a "tyre boot". This is a strong, flexible patch placed on the inside of the tyre to cover the hole. You can use a dedicated product, but in an emergency, a folded-up banknote, a piece of an old energy bar wrapper, or a section of an old tyre will work to get you home.

The World of Tubeless

Many modern bikes, especially mountain and gravel bikes, now use tubeless tyres. These systems use a liquid sealant inside the tyre to automatically plug small punctures, eliminating the need for an inner tube. While the setup is more complex, they offer better puncture resistance and the ability to run lower pressures for improved grip. If you find yourself getting frequent flats, converting to a tubeless setup might be a worthwhile upgrade.

CO2 Inflators for Speed

For racers or anyone wanting the fastest possible roadside repair, a CO2 inflator is a great tool. These devices use a small, pressurised cartridge of carbon dioxide to inflate a tyre in seconds, far quicker than a mini-pump. However, they are a one-shot deal, and CO2 leaks out of rubber faster than air, so you'll need to re-inflate your tyre with a regular pump later on.

How To Change A Bike Tire FAQ

Can I patch an inner tube instead of replacing it?

Yes, absolutely. A good quality patch, properly applied, is a permanent and reliable repair. Carrying a small patch kit is lighter and cheaper than carrying multiple tubes. However, changing the tube is often faster and easier on the roadside, and you can take the punctured tube home to patch it in a clean, controlled environment.

How often should I change my bike tyres?

This refers to the tyre itself, not the inner tube. There's no set mileage. You should replace your tyres when they show significant signs of wear. Look for a flattened centre profile (a 'squared-off' look), cracks in the sidewall, numerous cuts and nicks, or when the tread wear indicators (if present) are gone. Riding on worn-out tyres dramatically increases your risk of punctures.

What's the difference between Presta and Schrader valves?

Presta valves are thin, typically found on road and higher-end bikes, and have a small locknut at the tip that you must unscrew before inflating. Schrader valves are thicker, the same type used on cars, and have a spring-loaded pin in the centre. Your rim will be drilled for one type, so you must use a tube with the matching valve. Most pumps can accommodate both types, sometimes requiring you to reverse an internal part in the pump head.

Do I need any special tools?

The only truly essential, specialist tools are tyre levers. While you can sometimes remove and refit a tyre with your bare hands, many are too tight to manage without levers. Everything else—a pump and a spanner for non-quick-release wheels—is a fairly standard tool.
