1. Find The Puncture On Your tire
This can be done by pumping up the tube a little and sticking it in a pail of water, so you can see the bubbles. Then use a tire tube patch kit to repair the hole, or replace the tire. Inspect the bike for glass, metal bits or anything that could be causing the flat. It’s best to fix the flat immediately, rather than letting it go for too long, as this can cause additional damage and even make you lose control of your bike.
2. Remove The Tube And Examine
Once you have a look at the tube, try to match it up with the hole on your rim and identify the source of the flat so that you can avoid repeating it. This is a good way to ensure you don’t get another one with your replacement tube, and it can save you a lot of time and hassle when fixing your flat. If the puncture is a bit of sharp debris, it’s better to patch it before replacing the tube, so you don’t re-puncture the flat again. Once you’ve patched the tire, remove the old tube and inflate the new one.
When you’re inflating the new tube, be careful not to hit it with too much force or it could break. This can be especially dangerous on a new tube since it’s so delicate, and it can easily break on the inside of the rim. If you are trying to patch a flat tire, apply the sealant or glue and let it dry for 2 minutes before riding your bicycle again. This will help the patch to stick better and prevent it from peeling off or cracking.
4. Final Checks
Check to make sure the tire is seated properly. You can do this by looking for a ridge about 1/8 of an inch above the rim on each side of the tire. If the ridge isn’t there or if it is too far out, you need to adjust the tire. And once you’ve inflated the repaired or replaced tube to the proper PSI, it’s finally time to get your bicycle back on the road! Remember, it’s always best to get your bike repaired before you head out on a long ride so you can be prepared in case the weather turns bad or the traffic gets worse!
