Tire Flat Spotting


Symptom: flat tire

Diagnostic: tire damage that requires repair

Most punctures, nail holes or cuts up to 7 mm (¼") confined to the tread may be satisfactorily repaired by a trained professional using industry-approved procedures.


Change your flat tire out with your spare tire. Then visit an authorized Michelin tire dealer for an inspection as soon as possible. They can then determine what damage (internally as well as externally) your tire has, and whether to repair or replace your tire.

Symptom: underinflated tire

Diagnostic: underinflation

A tire is called underinflated when it doesn’t have sufficient air pressure to meet the vehicle manufacturer’s recommended psi (pressure per square inch). Underinflated tires lead to flats and tire blowouts.


  • reduces tread life through increased tread wear on the outside edges (or shoulders) of the tire
  • generates excessive heat, which reduces tire durability and can lead to tire failure
  • reduces fuel economy through increased rolling resistance (underinflated tires make your vehicle work harder).

Add air to your tire until it reaches the proper air pressure (psi, as measured by an air pressure gauge). To find the proper air pressure, consult your vehicle’s owner’s manual or find your recommended psi on the sticker on your door jamb.
