3. VERIFY L-RING SIZE
Check | Correct | Wrong |
Base ID | Sits in groove with light stretch | Too loose |
Lip Height | 0.20"--0.30" above groove | Crushed or too tall |

4. LUBRICATE
Silicone spray on:
L-ring (both sides + lip)
Rim groove
Tire bead (inside)
NO PETROLEUM --- destroys rubber.

5. INSTALL L-RING
Start at valve stem → work around.
Base in groove, lip facing OUTWARD (toward tire).
Roll lip with thumbs --- must stand upright.

6. MOUNT THE TIRE
Lay tire on rim --- bottom bead first.
Use plastic irons --- lip must stay under bead.
Top bead last --- push lip inward if needed.

7. INFLATE SLOWLY
Reinstall valve core.
10 PSI first → check lip is under bead.
Inflate to 40 PSI → beads "POP".

24-hr hold | <1 psi drop |
Low-PSI test | Run at 6--8 psi --- no slip |
