1 Remove the nuts that secure the wheel to the frame. If you cannot unscrew, use a special tool. Silicone grease or even vegetable oil will work. (Many modern bicycles do not have nuts. They have a quick release mechanism that can be easily loosened and the wheel removed.)

2 Loosen the brake, if you have one on your bike, as it will interfere with wheel removal. Different bikes will have different brake systems, but you will probably be able to remove the brake cable from the connector on the brake lever. On some brake systems, it is necessary to loosen the cable from the clamped position.

3 Pull out the wheel. To do this, you may need to disconnect the brake pads, and if you are removing the rear wheel, you will need to remove the chain from the sprocket (shifting to lower gears will make it easier to remove the chain). The front wheel is a little easier to remove.

4 Fully deflate the wheel by pressing the valve in the nipple. If the wheel has a French valve (presta valve), you need to unscrew the top of the stem to release the air. At this point, you also need to remove the retaining ring (if you have one on your bike) that is screwed to the bar and flush with the rim.

5 Squeeze the tire and walk around the entire circumference of the rim. Compression will help release the air.Also, by compressing the tire around the entire circumference of the rim, it will be easier to remove.

6 At the bike shop, you can buy a special "shovel" (like a shoe) that will make it easier to remove the tire. However, you can use a spoon or something similar, but there is a risk of damaging the wheel rim or puncturing the tube. Next, take 2 shoulder blades and insert them under the tire at a distance of 10-15 cm from each other. Then we take one key and carefully move in a circle in the opposite direction from the other key. The tire will then be removed halfway.

7 Remove the camera.

8 Swing the pump several times to fill the chamber with air. Examine the camera, find the hole through which the air passes. The best way to find the hole is to dip the camera in water. Bubbles in the water will tell you where the air is leaking.

9 Carefully check the inside of the tire around the entire perimeter; also inspect the rim for glass, nails, or any other object that could puncture the camera. Be careful when checking the tire to avoid injury from a nail or glass shard. If you find any sharp objects, be it a nail or a shard of glass, be sure to remove them with tongs or pliers. Adjust the rim tape to cover the protruding spokes.

10 Repair hole or replace tire / tube as needed. If you bought a new camera, unfold it, remove the plastic cap and retaining ring.

11 Place the new tube on the tire; make sure you don't twist it. Then pump up the camera. If you pump up the tube, you can avoid pinching it while installing the tire on the rim.

12 Put on the tire on each side in turn. This process is not easy, however it is best not to use a spatula or screwdriver or similar, otherwise you risk puncturing a new camera. The direction of travel must be marked on the tire in order not to put on the tire backwards. Insert one side first, then loosen the partially inflated tube and slide on the other side.

13 Make sure the camera is seated correctly, that the screw is on the retaining ring. Inflate the tube slowly and carefully to make sure the tire is level and not pinched anywhere.

14 Remove the pump and hand tighten the French valve and retaining ring.

15 Now you can put the wheel in place.

16 Secure the brake pads and replace the chain if you removed the rear wheel.

17 Good luck on the road!

Tips

Take care that there are no hot objects near the camera. The heat increases the pressure inside the chamber, which can cause it to explode!
Before inflating the camera with air or placing it in the tire, it can be dusted with talcum powder.

Warnings

Inflate the wheel at the pressure indicated on the tire. If pumped over, the tube / tire may burst.
There are different types of valves, so get a tube for the hole in the rim.
Under no circumstances must there be oil on the surface of the brakes (pads)! It should not be on the rubber and the camera either.
If your bike has rear brakes, be very careful with the axle. Move it to a safe place while changing the tire. Just bending the bridge a little, you will have to buy a new one.
After 10 years, tires usually deteriorate regardless of operating conditions, so pay attention to their condition.
If cracks appear on the tire (especially for the cord), then it is better to replace it with a new one.
After the puncture, you need to carefully examine the tire in order to detect the foreign body and remove it.
Before installing the camera, be sure to pump it up a little. This will help detect another puncture, if any. It also makes it easier to fit into the rim.
Be careful not to pierce the tube when removing the tire.
