The dimensions of the lug nut socket for the Mazda CX-9 vary depending on the year of manufacture. Prior to 2018, Mazda utilized a 21-millimeter hex head size, whereas since 2018, they have switched to a 17-millimeter size. Each wheel is secured with five lug nuts, and when replacing them, it is essential to ensure that the tapered end faces the rim. This not only guarantees that the wheel is centered but also prevents damage to the tire. Installing them incorrectly could potentially cause the rim to crack and, over time, could result in the wheel detaching while driving. Tighten the lug nuts in a crisscross pattern to the recommended torque: 90 ft-lbs for AWD models and 105 ft-lbs for the base model.
