This video will go through everything you need to know to change your flat tire. See one being changed in about a minute - no reason to lose a lot of time on race day if you practiced.

Dean and Mark of the Massachusetts Fitwerx bicycle shop will show you how to change a flat tire in about a minute.  See how fast a tire can be changed at the end of the video.

Tools and Materials:

• Tire Levers
• Extra Tube
• Inflator 
  
  REMOVING THE TIRE

1. Remove the wheel, let any remaining air out of the tire.
2. Start on the side of the tire opposite the valve stem.
3. Use the cup end of the tire lever to pry the tire off of the rim, attach the hook-end of the lever to the spoke.
4. Repeat 4"-6" away from the first tire lever.
5. With the second or third tire lever, you can slide it around the spoke to remove the rest.
6. Remove the tube from the tire.
   
   FIND OUT WHAT MADE THE FLAT
    
7. Inflate the tube and listen to try to find the cause of the flat.  Spraying the tube with a liquid will let you see the bubbles from the leak.
8. Check to make sure there is not something still lodged in the tire itself where the tube had a hole.
9. Check to make sure that your rim tape is covering all of the spoke holes.
   
   INSTALL THE TIRE
     
10. Insert the valve stem into the rim. 
11. Position the tub into the tire.
12. Start at the valve stem and work the tire back onto the rim until it is too tight to go any further.
13. Using your tire lever, push the remaining tire back onto the rim in 1/2" increments until it is all on the rim.
14. Inflate your tire with about 40-60psi and check to make sure the tire is fully seated on the rim.
15. Spin the tire to make sure that there are no bumps on the tire from the tube not being set correctly.
16. Continue to inflate your tire up to the recommended psi.
