My tire has gone flat. Is this covered by your warranty?

There may be a circumstance where air loss can be covered by warranty, however, this can only be determined when inspected by a tire professional at a Michelin authorized dealer.

Some common causes of sudden or slow air loss that are not covered by warranty are:

Road hazard injuries (punctures, cuts, impact damage to the liner, ply material or sidewall rubber).
Valve stem or core air loss form damage, loose or aged rubber stem.
Air loss from the bead seating area (corrosive buildup on the wheels which prevents a proper seal between the wheel flange and the tire beads, bead seating area damage from accidental mounting or dismounting, foreign material between the rim flange area and the tire bead seating area, bent rim flange).
