If you know how to deal with it, it’s no big deal to change your bicycle tire after a puncture. This will eventually happen whether you are riding on a flat road, a rugged gravel road, or a rugged monorail trail, so you might as well prepare the necessary tools and knowledge to solve the problem.
Below, we will detail everything you need to know about how to change your bicycle tires. For tools, you should always carry a tire lever, a spare tube of the correct size, and an inflation device, whether it’s a small pump or a CO2 cylinder. You may also need a patch kit or tire plug, which will come in handy for some riders. If you are using a tubeless tire, scroll down to skip to the tubeless section.
Start by removing the wheels. Keep your bike upright, and if the rear wheel is flat, shift the transmission to the hardest gear. If your bike has rim brakes (many bikes are still in use), you may also need to release the brakes.
Next, place yourself on the non-drive side of the bicycle (opposite the chain), and then open the quick release or loosen the axle to remove the wheel.
Now you can remove the tires. Hook the round end of a tire lever under the tire bead (outer edge) to remove it. Fix the other end to the spoke to hold the lever in place and prevent the unmounted tire from springing back to the rim. Then hook the second lever under the bead next to the first one and push it clockwise around the rim until one side of the tire comes off. You do not need to completely remove the tires.
Find the culprit
After the tire is loose, pull out the old inner tube (if applicable) and look for the source of the puncture, which may be thorns, glass pieces or other sharp objects. Carefully slide your fingers along the inside of the tire and rim, making sure that nothing sharp is left; otherwise, you may get another apartment. Also check the outside of the tire and again look for any foreign objects that may still be stuck in the rubber.
If you are using a pipe and want to do some detective work, inject some air into the old pipe to find the leak. The two holes side by side indicate pinching, and the inner tube is sandwiched between the tire and the rim. A single hole indicates that your apartment is most likely caused by a sharp object. By aligning the inner tube with the tire using the valve as a reference point, you can carefully check the area where the hole is located to ensure that the culprit is removed.
Fix the problem
If you are a thrifty type who likes to reuse old pipes, or if you get multiple units during the ride and don’t have more spare parts, then you can use a repair kit to repair your pipes. If you have a new tube, please skip to the next section.
First clean the perforated area and rough the surface with emery cloth. For a non-adhesive patch, just stick it on the hole and press firmly. For patches that require glue, add a thin layer of glue to the tube and patch. Wait for the glue to become sticky, then attach the patch and press firmly until it adheres.
If you prefer to reuse old pipes or run out of spare parts, you can try to repair the holes with a repair kit.
Now inflate your new or repaired tube to keep it in shape. This makes it easier to place inside the tire. Next, install the valve stem directly in the valve hole of the rim and position the inner tube inside the tire. Roll the tire rim away from yourself by hand and reinstall the tire on the rim. Try not to use the lever to reinstall the tire, because you may accidentally puncture the new inner tube. When you reach the valve stem, tuck the sides of the bead into the lower part of the rim, and then push the valve stem upwards so that the inner tube enters the tire.

By gently pushing the tire aside while working around the rim, check to make sure that the tire bead is not pinching the inner tube. Then inflate to the proper PSI and check that the beads are properly seated.
Reinstall the wheel
If everything is normal, please re-install the wheels and make sure that the quick release lever or the barrel shaft is on the other side of the power transmission system.
If your rear wheel is flat, place the top of the chain around the smallest gear on the flywheel, and then carefully push the wheel back into the frame. Turn off the quick release device (and rim brake, if applicable) or reinsert the tube axle into the frame and hub and tighten them. Finally, raise the rear wheel and rotate the crank once to make sure everything is back in place and running smoothly. If all goes well, please re-ride the bike and enjoy the rest of the journey.
Or insert a tubeless tire
For tubeless settings—almost the standard on mountain bikes, and growing in popularity on gravel, cross-country bikes, and even some road bikes—your sealant should work without you even realizing it. Be sure to check your sealant regularly (approximately every three to six months) to ensure that the tires are adequate and not dry, and to maintain normal use.
But if there are larger punctures or sidewall tears, you may need a tire plug to prevent air loss. The plug kit comes with a small piece of rubber and an insertion device that allows you to insert the hole without removing the wheel. After finding the puncture and inserting the rubber plug, reinflate the tire to the proper pressure to see if it has air. If so, please start riding again and check the repairs frequently to make sure it stays firm. You can also add more sealant, but you need to bring the spool removal tool and a small bottle of sealant to ensure stability
If the air leak is caused by a puncture that is larger than the plug repair while riding, you can try to patch the tire or boot. But a fair warning: the dirt around the tire is too large and the area is not thoroughly cleaned, and it may be difficult to apply a patch on a tire coated with sealant. Adding more sealant or patch can also create another problem, because let all the air out and break the seal between the rim and the tire. It can be difficult to reinstall the bead onto the rim on the spot. The easiest way to ensure that your tires keep air at this time is to simply use a spare emergency tube to complete the ride and solve it at home or bicycle shop.
Tyre inflation method
After carefully assembling the tire and the wheel hub and filling it with a little air, test whether there is any air leakage, manually adjust the waterproof line (safety line) and the outer edge of the wheel hub to maintain a certain roundness, and then inflate to standard air pressure. .
Before putting the tire back into the car, you can use detergent to clean the tire tread, so that the tire life will be longer

Put the tires back on the car
Ignore the above point. If you change gears, you must first remove the rim without a tyre, install the inner tube first, first blow 20% of the air, and then align the valve core with the eye on the rim, then put it on the rim and then put the tire cover Use a small crowbar to pry in the outside of the inner tube (note that one side enters the rim first) and use a small crowbar to pry it in (this process should be careful not to sandwich the inner tube between the outer tire and the rim) and then inflate 40% of the air. Flick the independent rim on the ground a few times (to prevent the inner tube from being pinched) and then assemble the tire on the bicycle. Tighten the axle (!!!) Finally, it is finished! !
