Things You'll Need:
- Crescent wrench (monkey wrench)
- Hammer
- Clean rug
- Crow bar
- Cup of soapy water
- Air compressor
-
Step 1
Use a crescent wrench to unscrew and remove the lug nut and washer on the brake disc side of the tire. Then, pull the lug nut out and set it aside.
-
Step 2
Push the tire forward and roll the chain off the tire's sprocket. Gently slide the tire away from the tire and out of the braking assembly. Set the tire on a clean rug, sprocket side down.
-
Step 3
Use a flathead screwdriver or knife to press the core of the valve stem on the tire, and let all the air out of the tube.
-
Step 4
Pull up one side of the tire, using a crow bar, working your way from the point just above the valve stem, all the way around the tire. Reach under the tire and pull the tube out of the rim. Pull the rest of the tire up and off the rim.
-
Step 5
Press a side of the new tire onto the rim, making sure it is facing the correct way. Slide a new tube into the tire, matching it up with the valve stem.
-
Step 6
Use the crow bar once more to pry the other side of the tire back onto the rim. This is the point where many people end up pinching the tube. To prevent this, work slowly, watching under the edge of the tire, to make sure that the crow bar doesn't hook on the tube at all. Patience is key to prevent the tube from being pinched.
-
Step 7
Stand the tire on end, and pour a small amount of soapy water around the tire on both sides, just so it drizzles inside the rim. This will allow the tire to slide out onto its bead much more easily.
-
Step 8
Pump the tire up to the desired hardness, making sure the tire pops onto its bead. If the tire won't pop out, try thumping on it with a hammer several times.
-
Step 9
Place the tire back on the motorcycle just the way you removed it. Make sure that the brake disc is placed correctly within the braking assembly. Roll the chain gently back over the tire's sprocket. Slide the lug bolt back through the axle shaft, and replace the lug washer and nut.
