Steps:

1. Unscrew the axle nut with a 19 mm wrench.
2. Unscrew the the axle bolt with a 19 mm socket wrench.
3. Remove the wheel from the wheelchair.

4. Insert the 19 mm socket wrench between the rubber tire and the metal frame.
5. Any rigid flat metal object can be used for this step.
6. Carefully slide the 19 mm socket wrench all the way around the tire. Bend the wrench down to pop the tire out of the bead of the rim.
7. When undoing the tire, be careful using the back of the wrench because the tool can damage the tire tube and or wheel frame.
8. Reach inside the tire and remove the tube from the metal frame.

9. Take the inner tube from inside the tire and submerge the tube in water.
10. Squeeze the tube gently looking for bubbles from the tube in the water.
11. You can use where the bubbles are forming to locate the hole in the tube.

12. Dry off the tube.
13. Pull the tube out of the water and mark the location of the hole on the tube so that it can be found again.

14. Use sand paper to texturize the tire tube.
15. Wipe off any excess rubber that was sanded off the tube.

16. Apply a thin layer of rubber cement over the area that was marked.
17. The layer should be slightly bigger than the size of the hole.
18. Let the rubber cement set for 5 minutes.
19. Peel the patch off of the plastic backing.
20. Place patch over the area with the rubber cement and firmly press down until the patch is securely attached.

21. Feel along the tire to check for and remove any objects stuck in the tire before replacing the tube.
22. Line up the air valve on the newly patched (partially deflated) tube with the hole on the metal frame before trying to insert the tube.
23. Working all around the tire, carefully push the tube back into place inside the tire.

24. Inflate the tire to 50 psi. If there is no gauge, inflate the tire until the tire is hard.

25. Insert the axle bolt into the center of the rear wheel.
26. Insert the wheel with the axle bolt into the lower back of the frame by screwing in the bolt.

27. Secure the nut on the opposite side of the axle bolt and wheel. Tighten with 1/2 in or 19 mm wrench.
