Figures marked "Owner's manual" link to the maker's own document. "Reported" figures are the maker's, read from a copy we could not get from the maker directly. A figure marked ≈ has been converted from the unit the manual prints. Nothing here has been checked against your vehicle: if it disagrees with the placard on the door jamb, the placard wins.

Tire pressure questions
What should the tire pressure be on a Mazda CX-90?
It depends on the tire size. For the sizes Mazda lists, the cold pressure is 36 psi at the front and 36–39 psi at the rear. Find your size in the tables above, and check the tires cold.
What size tires does a Mazda CX-90 take?
Mazda fitted the CX-90 with 255/60 R18, 265/55 R19 and 275/45 R21, depending on the model year and trim. The size is printed on the side of your tire; the pressures above are listed by size.
Where is the tire pressure placard on a Mazda CX-90?
On the driver's door jamb — the Tire and Loading Information placard. It gives the same cold pressures as the owner's manual, which is where the figures on this page come from; if the two ever disagree, go by the placard on your vehicle.
