Make Your Wire Wheels Tubeless

1. Check wheel run out, correct if necessary.

2. Tighten all spokes to specified torque.

3. Thoroughly clean and degrease inside of wheel. Even a small spot of dirt or grease could keep the Silicone from adhering properly and you'll have a leak.

4. Break the glaze a bit on the chrome inside the wheel with sanding cloth.

5. Install the tubeless valve stem correctly and with care. You may have to drill a larger hole. Place a small piece of tape over the inside opening to protect the opening from the silicone.

6. Fill all spoke socket holes completely with "Silicone II Aluminum and Metal formulation"  Fill around spoke sockets completely. This is an extra step for those who use the rim band. 

7. Allow to cure for 24 hours. This is critical.

8. Alternatively or additionally, cover the spoke area with silicone lavishly and fit the rim band over the spokes. Allow to dry a bit.
