Things You'll Need:
- Screwdriver
- Bicycle pump
- Adjustable wrench
- Street tire (the same width as your mountain tires)
-
Step 1
Remove the entire wheel from the bike. Use the wrench to loosen the nuts that secure the axle, and slide the wheel out.
-
Step 2
Connect the pump to the tire, but do not pump in air. Instead, use the pump to drain the air from the tire. Some pumps are reversible, but even if your pump is not reversible you can simply hold the valve open and let the air drain on its own.
-
Step 3
Use the screwdriver to pry one edge of the tire out of the wheel rim, all the way around the circumference of the wheel.
-
Step 4
Remove the inner tube from the tire, extracting it in between the wheel rim and the edge of the tire you have pulled out. This will protect the inner tube from being damaged while you change the tires.
-
Step 5
Remove the other edge of the mountain tire, using the screwdriver as necessary.
-
Step 6
Slide one edge of the street tire into the wheel rim. Make sure the replacement tires are the same width as the original tires for a good fit.
-
Step 7
Reinsert the inner tube and align it carefully along the center of the wheel rim.
-
Step 8
Use the screwdriver to wedge the final edge of the new tire into place within the wheel rim.
-
Step 9
Inflate the new tire to proper pressure.
