Changing a motorcycle tire involves a series of methodical steps, from safely removing the wheel to properly seating the new tire and ensuring correct inflation. With the right tools and patience, it's a task many riders can accomplish at home.
Essential Tools for the Job
Before you begin, gather the necessary tools. Having everything organized will make the process smoother and more efficient.

| Tire irons (at least 2-3, with rim protectors) | Pry the tire on and off the rim. | |
| Tire lubricant (tire soap, Windex, or specialty bead lubricant) | Aid in breaking the bead and mounting the new tire. | |
| Tire Installation | Air compressor (with pressure gauge) | Inflate the new tire. |
| Rim protectors | Prevent scratching or damaging the rim with tire irons. | |
| Cleaning & Prep | Wire brush, rags, degreaser | Clean the rim and inspect for debris. |
Step-by-Step Guide to Changing a Motorcycle Tire
Follow these steps carefully to ensure a successful and safe tire change.
1. Preparing Your Motorcycle and Removing the Wheel
Begin by preparing your motorcycle. Secure the bike on a stable stand (e.g., paddock stands) to safely lift the wheel you intend to remove. Remove any components that obstruct wheel removal, such as brake calipers (do not disconnect brake lines) or chain adjusters. Carefully loosen and remove the axle nut, then slide out the axle. Gently guide the wheel off the motorcycle, being mindful of spacers and brake rotors. It's helpful to lay the wheel on a clean, soft surface to prevent damage.
2. Deflating the Old Tire
Once the wheel is removed, the next step is to deflate the old tire completely. Use a valve core remover tool to unscrew the small valve core from the tire's valve stem. You'll hear the air rapidly escaping. Ensure all air has been released before proceeding.
3. Breaking the Tire Bead
The tire bead is the reinforced edge of the tire that seals against the rim. Breaking this seal is crucial. You can use a dedicated bead breaker tool, which applies pressure to separate the tire from the rim. Alternatively, for a manual approach, you can stand on the sidewall near the rim or use a C-clamp and block of wood. Apply tire lubricant generously around both beads to assist in the process. Work your way around the tire until both beads are fully separated from the rim.
4. Removing the Tire from the Rim
With the bead broken, you can begin to pry the tire off the rim.
- First Bead: Place rim protectors on the rim edge. Insert the tip of one tire iron under the first bead, leveraging it up and over the rim. Hold it in place. A few inches away, insert a second tire iron and pry up another section of the bead. Work your way around the rim, using your tire irons to gradually lift the entire first bead over the rim edge.
- Second Bead: Once the first bead is off, flip the wheel over. Push the tire down on the side where the first bead was removed, so that the opposite (second) bead sits in the "drop center" of the rim. This gives you more slack. Use your tire irons to pry the second bead up and over the rim, similar to how you removed the first.
5. Inspecting and Preparing the Rim
Before installing the new tire, it's essential to clean and inspect the rim thoroughly. Use a wire brush or rag with a degreaser to remove any dirt, old rubber, or corrosion from the rim, especially in the bead seating area. Check for any dings, dents, or burrs that could damage the new tire or tube (if applicable). If using a tube, inspect the rim strip for damage or displacement and replace if necessary. This step also involves checking the new tire for any manufacturing defects and ensuring its rotation direction (if marked).
6. Mounting the New Tire
Mounting the new tire requires careful handling to avoid damage to the tire or rim.
- Orientation: Identify the rotation direction arrow on the new tire's sidewall and ensure it will spin correctly when installed on the bike.
- Lubrication: Apply a generous amount of tire lubricant to both beads of the new tire and the rim flanges. This significantly reduces friction and makes mounting easier.
- First Bead: Place the first bead of the new tire over the rim. Use your body weight or gentle pressure to push it down into the drop center. Start by pushing a portion of the bead over the rim by hand. Then, use tire irons to work the rest of the first bead onto the rim, being careful not to pinch any tubes if it's a tubed tire.
- Second Bead: For the second bead, ensure the portion already on the rim is in the drop center opposite where you're working. Use tire irons to lever the remaining bead over the rim. This part can be challenging; take small bites with the irons and avoid excessive force to prevent damage.
7. Seating the Bead and Inflating
Once the new tire is on the rim, you need to seat the beads and inflate the tire.
- Valve Core Reinstallation: If you removed the valve core, reinstall it securely.
- Inflation: Connect an air compressor to the valve stem. Begin to inflate the tire. You'll hear a series of pops as the tire beads seat firmly against the rim flanges. Continue inflating until the tire is seated evenly around the entire circumference. Do not exceed the maximum pressure listed on the tire's sidewall during this process.
- Final Pressure: Once seated, adjust the tire pressure to the manufacturer's recommended level for your motorcycle (usually found in the owner's manual or on a sticker on the swingarm).
- Check for Leaks: Spray a soapy water solution around the tire beads and valve stem. Look for bubbles, which indicate air leaks. If bubbles appear, the bead may not be fully seated, or there might be a puncture.
8. Reinstalling the Wheel and Final Checks
Carefully reinstall the wheel onto your motorcycle, ensuring all spacers, brake calipers, and chain adjusters are correctly positioned. Tighten the axle nut and any caliper bolts to the manufacturer's specified torque settings using a torque wrench. Check your brake system operation before riding.

Important Considerations for Tire Changes
Tubed vs. Tubeless Tires
The process described is largely applicable to both types. However, if you have a tubed tire, be extra careful not to pinch the tube with tire irons during installation. Always replace an old tube with a new one when changing a tubed tire, as they can stretch and weaken over time.
Tire Balancing
After changing a tire, it's highly recommended to balance the wheel. An unbalanced wheel can lead to vibrations, premature tire wear, and compromised handling, especially at higher speeds. This typically involves using a wheel balancer and adding small weights to the rim to achieve equilibrium. For a deeper dive into why this is important, consider Understanding Tire Balancing.
Safety First
Always work in a well-lit area, wear appropriate safety gear (gloves, eye protection), and ensure your motorcycle is stable. If you're unsure about any step, consult a professional mechanic.
