If you're tired of changing flat tires or want to improve performance by reducing the weight of your bike, consider getting a tubeless tire system for your mountain bike. Tubeless tires are less likely to puncture and pinch flats are all but impossible thanks to the lack of a tube. Tubeless tires run on low pressure, allowing you to have maximum control of your ride. Another benefit is that some tubeless systems are lighter in weight than tube-filled tires.
Step 1
Line up the tire logo with the valve stem and rotate the wheel 180 degrees so you begin working on the tire opposite from the valve stem. Slide one side of the tire over the rim until it pops into place within the rim. Do this all around the tire until you finish at the valve stem.
Step 2
Liberally lubricate the second side of the tire and the rim with soapy water. Beginning at a point on the tire opposite the valve stem, use your hands and fingers to push, pinch and roll the second side of the tire under the rim until the bead catches in the rim well. Finish at the valve stem.
Step 3
To create the air tight seal and fix the bead in place, attach an air compressor to the valve or use a manual pump and fill the tire to 40 pounds per square inch. You might hear popping sounds as the bead seals to the rim.
Step 4
Deflate the tire to verify that the bead is locked and connected to the rim. If it isn't, repeat Step 3.
Step 5
Once your tire is sealed, re-inflate the tire to your intended psi value.
Tips and Warnings
- Ensure that your tire and rim are compatible. Look for products marked UST. An alternative is to use a conversion kit, but this will extend time to your installation.
- You might be tempted to use tire levers but only use them as a last resort. Incorrect use or slippage could cause damage to the tire's bead, rendering the tire unable to form a seal and hold air.
Things You'll Need
- UST rim and tire
- Air compressor or manual pump
