Essential Tools and Supplies for Your Rear Tire Swap
Before you even think about loosening a lug nut, having the right tools makes all the difference. A well-stocked toolkit is your best friend when you’re miles from civilization.
- Socket Wrench and Sockets: You’ll need a socket set that includes the correct size for your rear axle nut. Often, this is a large metric size.
- Torque Wrench: This is crucial for tightening the axle nut to the manufacturer’s specifications. Overtightening or undertightening can be dangerous.
- Tire Levers: A set of sturdy tire levers will help you pry the old tire off and the new one on. Metal ones are generally more durable than plastic.
- Tire Iron: Similar to levers, but often with a specific shape for bead breaking.
- Valve Stem Tool: For removing and installing the valve core, which is essential for deflating and inflating.
- Bead Breaker: This tool helps to unseat the tire bead from the rim. Some motorcycles have built-in ones, or you might need a portable one.
- Air Pump or Compressor: You’ll need to inflate the new tire. A portable 12V compressor is a lifesaver.
- Tire Mounting Lube: This makes sliding the new tire onto the rim much easier. Dish soap and water can work in a pinch, but dedicated lube is better.
- Gloves: To keep your hands clean and provide a better grip.
- Shop Rags or Towels: For cleaning up.
- Wheel Chocks: To prevent the bike from rolling.
- Jack or Lift: To safely support the motorcycle and lift the rear wheel off the ground. A motorcycle-specific jack is ideal.
- New Tire and Tube (if applicable): Ensure you have the correct size and type of tire. If you’re running a tube-type tire, have a new tube ready.
- Rim Strips (if applicable): For tubeless setups, check the condition of your rim strip.
- Optional: Tire Plug Kit: For temporary repairs on tubeless tires if you don’t have a spare.
Preparing Your Motorcycle for the Rear Tire Change
Safety and stability are paramount when working on your motorcycle. You don’t want your bike tipping over while you’re wrestling with a tire.
Securing the Motorcycle
First, find a level, stable surface. Avoid soft ground or slopes. Engage the parking brake if your bike has one, or use wheel chocks on the front wheel to prevent any movement.
Use a motorcycle jack or a sturdy block of wood under the frame to lift the rear of the bike. You want enough clearance to remove the wheel completely. Ensure the bike is stable on the jack before proceeding.
Removing Loose Components
Before you can access the rear wheel, you might need to remove a few things. This varies by bike model.
- Exhaust Canister: On some bikes, the exhaust can be in the way of the rear wheel. You might need to unbolt it.
- Chain Guard: The chain guard often needs to be removed to access the chain and sprocket area.
- Rear Fender or Hugger: Some fender designs can impede wheel removal.
- Brake Caliper: You’ll almost certainly need to remove the rear brake caliper from its mounting bracket. This allows the wheel to slide out freely.
Step-by-Step Guide: How to Change Back Bike Tire
Now that your bike is prepped and you have your tools, let’s get to the main event. Taking your time and following these steps carefully will ensure a successful tire change.
1. Loosen the Rear Axle Nut
With the rear wheel still on the ground (or at least before lifting), use your socket wrench to loosen the rear axle nut. You might need a breaker bar for stubborn nuts. Don’t remove it completely yet, just loosen it enough so it turns freely.
2. Remove the Brake Caliper
Unbolt the brake caliper from its mounting bracket. You don’t need to disconnect the brake line. Gently pull the caliper off the brake rotor and secure it out of the way. A zip tie or a piece of wire can hold it to the swingarm or frame.
3. Remove the Rear Wheel
Now that the axle nut is loose and the caliper is out of the way, you can lift the rear wheel completely off the ground.
- Adjuster Bolts/Nuts: Most bikes have chain adjusters on the swingarm. Loosen these nuts and turn the adjuster bolts to allow the wheel to move forward. This will give you slack in the chain and allow the wheel to slide out.
- Axle Removal: Once the wheel is positioned forward, you can fully remove the axle nut and then the axle itself. You might need to tap the axle gently with a rubber mallet to get it to slide out.
- Wiggle the Wheel Free: Carefully maneuver the rear wheel out of the swingarm. You might need to push the chain off the rear sprocket as you pull the wheel out.
4. Break the Tire Bead
This is often the most physically demanding part. The tire bead is the edge of the tire that seals against the rim. You need to break this seal on both sides.
- Use a Bead Breaker: If you have a dedicated bead breaker tool, follow its instructions.
- Manual Method: You can try standing on the tire (carefully!) or using the side stand of your bike to press down on the sidewall near the rim. Sometimes, clamping the wheel between your knees and using tire levers to pry the bead down works.
5. Remove the Old Tire
Once the bead is broken all the way around on both sides, you can start removing the tire.
- Deflate Completely: Ensure the tire is fully deflated. Remove the valve core with your valve stem tool if you haven’t already.
- Use Tire Levers: Insert a tire lever between the tire and the rim, prying the bead over the edge of the rim. Work your way around the wheel, using multiple levers to keep the bead pulled off.
- Second Side: Once one side of the tire is off the rim, flip the wheel over and repeat the process for the other side.
6. Inspect and Clean the Rim
With the tire off, take the opportunity to thoroughly inspect your rim. Look for any dents, cracks, or damage. Clean any dirt or old rubber residue from the rim.
7. Install the New Tire
This is where your tire mounting lube comes in handy.
- Lubricate: Apply tire mounting lube generously to the beads of the new tire and the rim edges.
- First Bead: Place the new tire over the rim. Start by pushing one bead onto the rim by hand as much as possible. Then, use your tire levers to work the rest of the first bead over the rim edge.
- Second Bead: This is the trickier part. Work the second bead onto the rim, starting opposite the valve stem. Use your levers to pry it on. You might need to push the tire down into the rim’s center channel to create slack.
8. Seat the Tire Bead
Once the tire is on the rim, you need to seat the beads.
- Inflate: Remove the valve core again. This allows air to flow in faster, helping to pop the beads into place. Inflate the tire rapidly. You should hear a loud “pop” or two as the beads seat against the rim.
- Check Seating: Inspect both sides of the tire to ensure the bead is evenly seated all the way around the rim. There’s usually a molded line on the tire sidewall near the rim that should be an even distance from the rim edge.
9. Reinstall the Wheel and Chain
Now it’s time to put everything back together.
- Position the Wheel: Maneuver the wheel back into the swingarm. You might need to rotate the wheel slightly to align it with the chain and sprocket.
- Install the Axle: Slide the axle back through the swingarm and wheel.
- Reattach Brake Caliper: Slide the brake caliper back onto the rotor and rebolt it to its bracket.
10. Adjust Chain Tension and Align Wheel
This is a critical step for safety and proper handling.
- Align the Wheel: Use your chain adjusters to align the rear wheel precisely with the swingarm markings. Ensure the wheel is straight.
- Set Chain Tension: Consult your owner’s manual for the correct chain slack. Adjust the adjuster bolts until the chain has the specified amount of free play. Too tight or too loose can cause serious problems.
- Tighten Axle Nut: Once the wheel is aligned and chain tension is set, tighten the rear axle nut. Do not guess the torque.
11. Torque to Specification
This is where the torque wrench is essential. Tighten the rear axle nut to the manufacturer’s specified torque value. This is a crucial safety step. If you don’t have a torque wrench, take it to a shop to have it torqued correctly.
12. Final Checks
- Spin the Wheel: Rotate the wheel to ensure it spins freely without any rubbing or binding.
- Check Brakes: Squeeze the rear brake lever several times to pump the brake pads back against the rotor. Test the brake’s effectiveness.
- Tire Pressure: Inflate the tire to the recommended pressure found in your owner’s manual or on the tire sidewall.
- Reinstall Components: Reinstall any parts you removed earlier, such as the exhaust, chain guard, or fender.
Common Pitfalls and How to Avoid Them
Even with a step-by-step guide, some issues can pop up. Being aware of these common problems can save you a lot of frustration.
- Stuck Axle: If the axle is difficult to remove, it might be corroded or dirty. Try wiggling it or tapping gently with a rubber mallet. Ensure all adjusters and nuts are fully loosened.
- Tire Bead Won’t Seat: This often happens if the tire isn’t properly lubricated, or if there’s a pinch in the bead. Ensure the bead is in the rim’s center channel. Sometimes, removing the valve core and inflating rapidly helps.
- Pinching the Tube: If you’re using a tube-type tire, it’s easy to pinch the tube between the tire bead and the rim. Inflate the tube slightly before fully seating the tire to give it some shape and prevent pinching.
- Incorrect Chain Tension: This is a major safety concern. Always refer to your owner’s manual for the correct slack.
- Overtightening/Undertightening Axle Nut: This can lead to wheel bearing damage, loosening of the wheel, or even accidents. Always use a torque wrench.
Frequently Asked Questions About Changing a Rear Bike Tire
How often should I change my motorcycle tires?
Tires wear out based on mileage, riding style, and road conditions. Visually inspect your tires regularly for tread depth, cracks, and bulges. A general guideline is to replace them every 5,000-10,000 miles, but this can vary significantly.
Can I use a car tire on my motorcycle?
Absolutely not. Motorcycle tires are designed specifically for the unique stresses and handling characteristics of a motorcycle. Using a car tire is extremely dangerous and can lead to a catastrophic failure.
What’s the difference between tubeless and tube-type tires?
Tubeless tires seal directly against the rim, eliminating the need for an inner tube. They are generally safer as they are less prone to sudden deflation. Tube-type tires require an inner tube to hold air and are often found on older bikes or certain off-road models.
Do I need to balance my motorcycle wheel after changing the tire?
Yes, balancing is highly recommended. An unbalanced wheel can cause vibrations at speed, uneven tire wear, and affect handling. Most tire shops can balance your wheel for you when they install the tire.
