Preparing Your Dirt Bike: Securing the Bike and Removing the Wheel

Before changing a dirt bike tire, properly preparing your motorcycle is crucial. This involves securing the bike to prevent it from toppling over and removing the wheel that needs the tire change. Here’s how to do it step by step:

Secure the Bike

  • Place your dirt bike on a stable and level surface. If you have a dedicated bike stand, use it to support the cycle.
  • Ask a friend for assistance if you don’t have a bike stand. They can help keep the process steady while you work on it.
  • Engage the bike’s transmission into gear (usually first gear) to lock the rear wheel in place. If you’re working on the front wheel, use a front wheel chock or have your helper hold the front brake to prevent it from spinning.

Remove the Wheel

  • If you’re changing the front tire, remove the front axle nut. Use the appropriate size socket or wrench to do this. Place the nut in a safe location so you don’t lose it.
  • Carefully slide the front axle out from the wheel hub, taking note of any spacers or washers on either side of the wheel. Keep these organized for reassembly.
  • For the rear tire, locate and remove the chain tension adjusters on both sides of the swingarm. This step is necessary to create enough slack in the chain for wheel removal.
  • Once the chain has sufficient slack, remove the rear axle nut using the appropriate tool. As with the front axle nut, could you keep it in a secure place?
  • Slide the rear axle out, and avoid spacers or washers. Keep them organized.
  • With the axle removed, carefully lower the wheel out of its position, not damaging the brake rotor or sprocket.

Now that you’ve secured your dirt bike and successfully removed the wheel that needs the tire change, you’re ready to move on to the next steps in the tire-changing process. These steps will involve tire removal and installation, which we’ll cover in detail in the upcoming sections.

Removing the Old Tire: Deflating the Tire, Breaking the Bead, Levering Off the Tire

The first significant step to replace a dirt bike tire is removing the old one. This process involves deflating the tire, breaking the bead, and levering the tire from the rim. Here’s a detailed guide:

Deflating the Tire

  • Make sure the tire is completely deflated before attempting to remove it. To remove the valve core, use a valve stem tool. This will let all of the tire’s air out. As the valve core is removed, hold onto it because you’ll need it later.
  • Gently push on the tire to ensure all remaining air is expelled. Confirm that the tire is completely flat.

Breaking the Bead

The bead is the tire’s inner edge that sits against the rim. Breaking the bead is necessary to separate the tire from the perimeter. You can do this using a bead breaker tool or a modified C-clamp:

  • Using a Bead Breaker Tool: Position the tire on the tire stand or a flat surface with the bead facing up. Place the bead breaker tool beneath the tire’s bead and apply downward pressure to break it loose. Move the device around the tire’s circumference to ensure the entire dot is free.
  • Using a C-Clamp: If you don’t have a bead breaker tool, a C-clamp with a soft-jaw attachment can work. Position the C-clamp so that one jaw is on the inside of the tire and the other is on the rim. Gradually tighten the clamp to break the bead.

Levering Off the Tire

Once the bead is broken, levering the tire off the rim is time. You’ll need one or more tire irons for this step:

  • Insert a tire iron between the tire and the rim, starting at the spot on the tire opposite the valve stem. Pry the tire’s bead over the edge of the trim using leverage. If your tire has an inner tube, don’t squeeze it.
  • Insert a second tire iron a few inches away from the first and repeat the process. Continue this process, gradually working your way around the tire until one side of the tire is completely off the rim.
  • Carefully remove the inner tube (if your tire has one) and set it aside.
  • Flip the wheel over and repeat the procedure opposite the valve stem to remove the other side of the tire.

Following these steps, you’ll successfully remove the old tire from the rim, preparing it to install a new tire or tube, if necessary. Proceed with caution, as excessive force can damage the rim or tire.

Inspecting the Rim: Cleaning and Inspection

Before installing a new tire or tube, inspecting and cleaning the rim thoroughly is crucial. A clean and well-maintained edge ensures a proper fit for the new tire and helps prevent issues down the road. Here’s how to inspect and prepare the edge:

Cleaning the Rim

  • They clean both rim sides of any dirt, debris, or leftover old tire material. Clean the area with a firm brush or a cloth to remove dirt and grime. Make sure the rim is free of any foreign objects and adequately clean.
  • If there’s any stubborn residue, you can use a mild degreaser or soapy water to help loosen it. Be sure to rinse and dry the rim thoroughly after cleaning.

Inspection of the Rim

  • Carefully examine the rim for any signs of damage or wear. Look for cracks, dents, or bends in the edge. Even minor imperfections can lead to tire mounting difficulties or affect tire performance.
  • Check the rim’s bead seating area. It should be smooth and free from any irregularities. Any rough spots or damage can make it challenging to install the new tire properly.
  • Look for any damage or protruding edges in the valve stem hole that can cause the inner tube to rip. If required, use a file to smooth off any jagged edges.
  • Ensure any rim locks or strips are in good condition and properly seated.
  • Verify that the rim’s size matches the tire size you intend to install. Check the markings on the edge to confirm the size.

Mounting the New Tire: Lubricating the Bead, Using Tire Irons, and Inflating the Tire

Now that you’ve inspected and prepared the rim, it’s time to mount the new tire onto it. This process involves lubricating the bead, using tire irons to secure the tire, and inflating it to the correct pressure. Here are the steps:

Lubricating the Bead

  • Apply a thin layer of soap and water solution to the inside of the tire’s bead and the rim’s bead seating area. This lubrication helps the tire slide onto the edge more efficiently and reduces the risk of damaging the tire or inner tube during installation.

Using Tire Irons

  • Begin by positioning one side of the new tire onto the rim. Start at the valve stem hole, as this can be a reference point for alignment.
  • Work the tire bead over the rim as far as possible using your hands. Then, insert one tire iron between the tire bead and the edge, a few inches from the valve stem.
  • Use light leverage to pry the tire bead over the rim’s edge. Take care to avoid damaging the tire or pinching the inner tube. To continue mounting the tire, gradually move the iron around the edge.
  • Insert a second tire iron a few inches away from the first, and repeat the process. Continue this process, alternating between the two tire irons until the tire is entirely mounted on one side of the rim.
  • Carefully insert the valve stem through the valve stem hole and secure it with the valve core, which you removed earlier. Tighten it to ensure it’s airtight.
  • Now, work on mounting the other side of the tire. Begin opposite the valve stem hole and use the same levering technique with the tire irons to carefully climb the tire onto the rim. Take your time to avoid damaging the tire or inner tube.

Inflating the Tire

  • Before inflating the tire, double-check that the tire bead is seated correctly on both sides of the rim. Ensure there are no pinches or folds in the inner tube, which can lead to air leaks.
  • An air compressor inflates the tire to the manufacturer’s recommended pressure. Refer to your bike’s owner’s manual for the correct PSI (pounds per square inch) or kPa (kilopascals) specifications. It’s crucial not to overinflate the tire, which can cause damage.
  • As you inflate, listen for any unusual sounds or air leaks. If you notice air escaping, stop inflation immediately and check for issues like improperly seated beads or pinched inner tubes.
  • Once the tire is inflated correctly, please give it a final inspection to ensure it’s evenly seated on the rim and properly aligned.

With the new tire successfully mounted, you’re one step closer to completing the tire-changing process. In the following steps, we’ll cover balancing and reinstalling the wheel on your dirt bike.
