1. Remove the bike wheel: First, you need to remove the wheel that needs the tire changed. If it's the rear wheel, you'll need to disengage the bike chain from the gear cassette. Use the fast-release lever or, if your bike isn't equipped with one, you may need to use a wrench to loosen the nuts on the wheel axle.

2. Deflate the tyre: If the tire still has some air, remove the cap from the valve located on the inner part of the wheel. Some bikes have a Schrader valve (same as car tire valves) and some have a Presta valve (these are long and skinny). For Schrader valves, press on the small pin inside the valve to let the air out. For Presta valves, unscrew the small nut at the top, then press to release the air.

3. Remove the tyre: Use a tire lever (special tool) to pry the tire off the bike rim. Insert the flat end of the tire lever beneath the tire edge and use it to pry up the tire, revealing the inner tube.

4. Remove the inner tube: Once the tire has been freed, reach in and gently pull out the inner tube.

5. Inspect the tyre and inner tube: Look for any punctures or sharp objects that may have caused any flats. If you found a puncture in the tube, you may need to either patch it or replace the tube.

6. Mount the new tyre or inner tube: If you're replacing the inner tube, inflate it just enough so it maintains its shape, then place it inside the tire. Make sure the valve stem is sticking through the valve hole in the rim. If you're replacing the tire as well, place one side of the tire onto the rim before putting the tube in. Then, tuck the other side of the tire into the rim, making sure not to pinch the tube.

7. Inflate the tyre: Using a bike pump, inflate the tire to the recommended PSI (found on the sidewall of the tire).

8. Replace the wheel: Place the wheel back onto the bike frame. If it's the rear wheel, you'll need to re-engage the bike chain with the gear cassette. Ensure the wheel is aligned correctly and, with the fast-release lever or wrench, secure the wheel back onto the frame.

9. Check everything: Test your brakes, ensure the tires are seated correctly, and take a short cautious ride to confirm that everything works as expected.

The rarest color of zircon is green. Green zircon acquires its color from natural radiation exposure, affecting its crystal structure. This process is unique and less common than the conditions that lead to other zircon colors, making green zircon scarce and highly prized among collectors. Other colors of zircon, such as blue, red, yellow, and brown, are more frequently found and are often enhanced through heat treatment. However, the natural formation of green zircon is a slow and less common geological phenomenon, contributing to its rarity and desirability in the gem market.
