Summarize this article in one sentence.
Go over each side of the wheel. Look along the rims. Confirm that the tires are evenly placed over the rims. Adjust if necessary. First, find their recommended air pressure, which should appear on the tire itself. Then remove their caps and fasten your bike bump to the valve. Inflate them slowly so you don't go over the recommended air pressure and burst your tire by accident. Once the tires are inflated, give them a spin. Make sure they're still seated evenly over the rims once they come to a stop. If not, release the air, readjust the tires, and repeat until they're in the proper position once inflated. Replace the valve cap when you're all done. Center the wheel evenly between its fork and place it into the front fork's drop outs. Open the brake to do so if necessary. Tighten all bolts. As you do, tighten each just a little bit at a time, move on to the others and tighten them just as much, and repeat until you're all done. Then double-check that the wheel is still centered between the fork. Many bikes have a quick release on the front wheel, which allows for easy installation and removal without tools. With the quick release lever open, slip the wheel onto the dropouts. Tighten the nut by hand until you need to use a bit of force to close the lever (enough to leave an imprint of the lever on your hand). Instructions for this step possibly vary the most between designs. Refer to your owner's manual for precise steps for your specific wheel.

Summary:
Make sure each tire is mounted correctly on its rim. Inflate the tires. Recheck how the tires are seated on the rims. Attach the front wheel.
