Tubeless losing air after 2 months: diagnostic checklist

6-step diagnostic

  1. Sealant level — top up if dry (60-80 mL)
  2. Valve — tighten, clean valve core
  3. Bead seating — check bead is in rim's central channel
  4. Rim tape — uniform, no holes, 2 layers
  5. Porous tire — soap test in basin
  6. Damaged bead — inspect with light
