Step 1: Get Materials
A pump, an extra tire, and the tire changing tools
Step 2: Check to Make Sure the Tire Is Flat
Press on tire to check sir pressure.
Step 3: Release Brake and Take Tire Off
All you have to do is loosen the brake and unscrew and take off the tire.
Step 4: Taking the Tire Off
Use the tire changing tools and put the flat end into the tire side, run the tool all the way around the tire, so half of the tire is not on the rim.
Step 5: Switch the Inner Tubes
Take the old inner tube out of the tire and inflate the new one just enough to give it some definition.
Step 6: Put the New Inner Tube Into the Tire
Start by putting the pump valve in first and than just rotate around the tire.
Step 7: Reconnect the Tire to the Rim
Use those useful nameless tire tools I told you about to put connect the tire and rim once again, the lash few inches are kind of hard but that's where we need to use some of that elbow grease.
Step 8: Put It All Back Together
Put the rim back on the bike than tighten it back on, after this you can retighten your brake.
Step 9: Now You Can Ride Your Bike
!Warning! Do not replace a tire that just popped, it will save you money to purchase a $5 patching kit rather than a $25 inner tube. Otherwise have fun.
