A flat tyre or worn tread always comes at the worst time. But you don’t need to rush to the bike shop, with the right tools, you can replace your bicycle tyre yourself. In this blog, we'll show you step by step how to replace your inner tube, rear tyre, or tubeless tyre.
When should you replace your bike tyre?
If you notice a tear in the sidewall, a smooth wear-through of the tread, or a puncture that can't be patched, it's time for a new tyre. It may also be time for replacement if your tyre won’t hold air, this could indicate damaged valve beads or an inner tube issue. A good tyre provides comfort, grip, safety, and reduces the likelihood of breakdowns. Stay alert to these signs and replace your tyre in time to avoid accidents and unsafe situations.
Replacing the front wheel tyre
Changing the front tyre is straightforward, there’s no chain or gears to deal with.
- Stabilise your bike by turning it upside down (resting on the saddle and handlebars). Release the quick-release or axle nuts and remove the front wheel from the fork.
- Release all the air from the tyre by opening the valve. Use a tyre lever to gently pry one side of the outer tyre away from the rim. Pull out the inner tube, then inspect the inside of the tyre for sharp objects, that'll stop your new tube deflating instantly.
- Slightly inflate the new inner tube and insert it into the tyre, making sure the valve pierces through the valve hole in the rim. Work the tyre bead fully back onto the rim. Check the tyre is seated properly, then inflate it to the correct pressure.
- Reinstall the wheel into your fork, tighten the axles securely, and check the wheel spins freely.
Extra tip: Properly inflated tyres make a world of difference. Use a reliable pump with a pressure gauge, such as the ACID Pump RACE UHP, to get it spot on.
Replacing the rear wheel tyre: a bit more involved, but doable
The rear tyre is a bit trickier due to the chain, cassette, and derailleur, but it's manageable:
- Stabilise your bike using a workstand, or flip it upside down. Shift into the smallest rear cog to release tension on the chain and make wheel removal easier.
- Open the quick-release or axle nuts and slide the wheel slightly backwards to remove it from the dropouts. Carefully lift the chain off the cassette and set the wheel aside, note the position of the chain and derailleur for reinstallation.
- Fully deflate the tyre. Press the valve to release lingering air, then use a tyre lever to unseat one side of the tyre from the rim, start opposite the valve and work towards it. Remove the inner tube and inspect the tyre inside and out for sharp debris using a torch if needed.
- Lightly inflate the new inner tube for shape, insert the valve through the rim, then tuck the tube inside the tyre. Seat both beads of the tyre, starting opposite the valve and finishing at the valve. Make sure the tube isn’t pinched between tyre and rim.
- Inflate to the pressure marked on the tyre sidewall, checking that the tyre seats evenly as you pump.
- Slide the wheel back into the frame, guiding the chain onto the smallest cog, ensure the derailleur positions properly and the axle sits correctly in the dropouts. Secure the quick-release or nuts, then check for alignment and smooth rotation.
Final check: test your brakes and ensure the derailleur shifts correctly. Once everything is in place, you’re good to go.
Extra tip: A well-inflated rear tyre improves comfort, grip and prevents premature wear on your cassette and chain. Regular tyre‐pressure checks are a must, especially for frequent or long rides.
Replacing just the inner tube
First, inspect the outer tyre to make sure there are no sharp objects. If it’s clear, reinstall one side of the tyre bead onto the rim. Lightly inflate the tube to give it shape and insert it into the tyre. Push the valve through the rim hole.
Now comes the trickier part: reseating the tyre fully. Begin opposite the valve and work towards it using your hands. If necessary, use a tyre lever, but be careful not to pinch the tube.
Inflate to the tyre’s recommended pressure, check everything again, and reinstall the wheel. Make sure the chain lines up correctly if you're working on the rear.
Replacing a tubeless tyre: a more technical process
Tubeless setups offer lower puncture risk, comfort and grip, but replacing them is slightly more involved:
- Deflate completely. Use levers to remove one side of the tyre. Dispose of any old latex sealant and thoroughly clean the rim.
- Inspect the tubeless rim tape and replace if damaged or worn.
- Fit the new tubeless tyre, then pour fresh sealant inside. Spin the wheel to evenly distribute it.
- Inflate firmly using a floor pump or compressor until the tyre beads “pop” into place. Check that the tyre seats evenly, then let the pressure settle to your riding pressure.
Handy tips
- Use tyre levers sparingly to avoid damaging the rim or tube.
- Check tyre rotation direction. Usually indicated by an arrow on the sidewall.
- Replace tyres early rather than too late. Worn tyres are more prone to punctures and compromise safety.
- Always refit the valve cap. It helps protect the valve from dirt and moisture.
