What's wrong?
The tires on the 2019 Mazda CX-9 carry the vehicle, hold air pressure, and use their tread to grip the road. The tread is the outer rubber layer that contacts the pavement and channels water away from the tire. On these vehicles, the concern is the original Sumitomo Falken ZIEX CT50 A/S tire installed in production.
During tire manufacturing, rubber compound meant for prototype production was mixed into the standard tread rubber. That incorrect compound reduced the strength of the tread rubber. As the tire rolls, heats, and flexes, the tread rubber can separate from the tire body and peel away. In NHTSA campaign 19V770, Mazda's filing says this does not break the base rubber or belt underneath, so rapid air loss or a blowout is not the stated failure mode. The concern is partial tread peeling that can make the vehicle unstable.
Owners can notice vibration, a flapping noise, partial rubber separation from the tread, or irregular tread wear before separation. Those signs mean the tire needs dealer inspection and replacement under the recall.
