How to replace a punctured bike tyre tube
Don't you hate that horrible feeling when you realize you've got a puncture to your bike tyre and you're far from home? You can either call your Mum to come and pick you up…OR: You can learn how to do it yourself and never need an emergency rescue ever again!
We like the second option best so never be stranded out in the middle of nowhere with a puncture to your bike tyre again with this handy "how to" guide by Kiwi Ironman athlete Simon Cochrane. Read up on this step-by-step process and have a practise and in next to no time you'll be a pro at getting back on the road after a puncture.
Tools you will need:
2 x tyre levers
1 x C02 inflator/mini hand pump
1 x new inner tube
What To Do Next:
1. Loosen your brakes and undo your quick release lever to remove your bike wheel.
2. Completely deflate the tube by pressing down on the inner part of the valve (remove the locking ring if you have one)
3. Loosen the tyre beads from the rim by squeezing the tyre – this will help when removing the bike tyre.
4. Take your tyre levers and place one between the tyre and the rim to lift the tyre up over the edge of the rim. Move around the rim about 15cm and do the same with the 2nd lever – you should be able to slide the lever around the rim to release the tyre off one side.
5. Remove the punctured tube and thoroughly check the inside and outside of the tyre for anything that may have caused the puncture. This could be glass, a sharp stone or a nail, so be careful not to slice your finger!
6. Partially inflate the new tube before inserting into the tyre (this helps it to keep its shape and not get twisted)
7. Carefully re-seat the tyre back onto the rim by rolling it using your fingers if possible – If not use a lever to assist with the last bit. (If it is a tight tyre, push the bead into the middle channel of the wheel to create some slack)
8. Inflate the tyre ensuring that the bead has popped back into place and is seated on the rim.
9. Fit wheel securely back into the bike, and adjust the brakes back up.
Get back to training! This whole process should take 3-5mins with some practise.
