What do you need to replace a Tomos tyre?

Make sure you have this to hand:

• New outer tyre (if you want to replace it as well)

• New inner tube

• Tyre levers

• Rim protector (strongly recommended)

• Tie-wraps / zip ties

• Tyre pump or compressor

• Spanner/socket set

• Lubricant (tyre paste or washing-up liquid / soap)

Step 1: Remove the wheel from your Tomos

Position your Tomos securely

Remove the Tomos front wheel or rear wheel

1. Removing the rear wheel? Then it helps to also loosen the chain. It’s not always necessary, but it does make the job a lot easier. Don’t know how to remove a chain, or simply want to know more about chains and sprockets? Click here for our blog about Tomos chains and sprockets
2. Disconnect the brake cable at the brake arm. Undo the nut and pull the cable out of the arm.
3. Then loosen the axle nut, but not all the way. Once the axle is loose you can slide the wheel out of the front fork or swingarm. Only on a new-model front fork do you need to fully remove the axle to take the wheel out.
• Pay close attention so you don’t lose any washers and spacers, and remember the order they are fitted in. Tip: Put everything back onto the axle straight away so you don’t forget the order and you don’t lose anything.
4. With the axle loose, you can remove the wheel from the front fork or swingarm.

Step 2: Remove the outer tyre and inner tube from the rim

1. Press the valve pin in to let all air out of the inner tube.
2. Use tyre levers (not screwdrivers!) and optionally rim protectors to prevent damage to the rim.
3. Lever one side of the outer tyre off the rim by placing the tyre lever between the tyre and the rim edge and carefully prying it over. Make sure you don’t catch the inner tube to avoid damage.
4. Now remove the inner tube from the outer tyre by undoing the valve nuts and pushing the valve out of the rim.
5. Replacing the outer tyre as well? Pull the entire outer tyre off the rim. This is easy by hand. If not, insert the lever again between the rim and the tyre, but this time work it between the entire tyre and the rim.

Step 3: Inspect the old tyre for damage

1. Inflate the old inner tube.
2. Coat the tube with soapy water or place it in water and look for escaping air bubbles.
3. Check the inside of the outer tyre and the rim for glass, stones or metal.
4. Feel it through and check properly, otherwise your new inner tube will be punctured again in no time.

Step 4: Fit the new Tomos tyre

When fitting a new Tomos inner tube and outer tyre there are two commonly used methods.

Method 1: Standard method

1. Lubricate the sidewalls of the outer tyre with tyre paste or soap.
2. Check the direction of rotation of the tyre (arrow on the sidewall).
3. Push one side of the outer tyre over the rim.
4. Place the new inner tube inside the outer tyre.
5. Insert the valve through the rim and tighten it lightly.
6. Inflate the inner tube slightly.
7. Push the last bead of the outer tyre over the rim.
8. Inflate the tyre fully and check it sits straight in the rim. Lock the valve with the nuts.

Tip: Don’t use tyre levers here to avoid pinching a puncture.

Method 2: Zip-tie method

1. Remove the outer tyre completely from the rim.
2. Place the inner tube inside the outer tyre.
3. Compress the tyre all the way round with zip ties.
4. Lubricate the sidewalls.
5. Insert the valve through the rim.
6. Push the complete tyre assembly over the rim.
7. Cut the zip ties and remove them.
8. Inflate the tyre and lock the valve.

Step 5: Refit the wheel on your Tomos

1. Refit the brake anchor plate into the rim.
2. Place the wheel back into the front fork or swingarm.
3. Slide the axle through the wheel and frame.
4. Fit washers, spacers and speedo drive correctly.
5. On the rear wheel, refit the chain and adjust it (2–3 cm slack).
6. Tighten the axle nut firmly.
7. Reconnect the brake cable and adjust it.

Always check the wheel spins freely and the brake works properly.

Conclusion

Replacing the tyre on your Tomos moped is a job you can easily do yourself within an hour with the right tools. Follow the steps in this blog carefully and make sure you have all the necessary materials ready before you start. Whether you choose the standard method or the zip-tie method, both are effective as long as you work carefully. Don’t forget to check after refitting the wheel that everything is tight and functioning properly. With a new tyre, you’re ready for many more safe kilometres on your Tomos moped!
