How to change a bike tire

Take the wheel off the bike.

Unscrew the valve cap and deflate the tube.

Empty it right out.

Pinch the tire and insert the tire lever.

It should come off pretty easily

Hook the tire lever to flip the bead of the tire outside the rim

Use the second tire lever in there and work around the tip

Pull out the inner tube

Put a bit of air in the tube to give it some shape - don't overinflate

Insert the valve stem into the hole of the rim

Begin to gently place the tube back inside the tire

Using your hands, begin to work the bead back into the rim

Move from one side to the other

Ensure the tube isn't caught in the bead or the rim

Inflate the tire to proper pressure and reattach your bike

Secure and tighten the wheel onto the bike

and you're good to go!
