Yes, the hub is identical
Same 5x114.3 PCD and same 66.1 mm centre bore: wheels from Infiniti QX55 bolt on and centre on Nissan Ariya without rings. You still need to check the offset and tyres, detailed below.
≈: width estimated from the original tyre size.
Wheel by wheel: offset and tyres
Each original wheel from Infiniti QX55 is compared with the one from Nissan Ariya of the same diameter: how much closer the wheel gets to the shock absorber or how far it sticks out of the wheel arch, and whether the tyre keeps the same overall diameter.

≈7Jx20 ET44 · 225/45R20 — Fits like the original
Compared with the original 8Jx20 ET45 on Nissan Ariya: shock absorber side −13.7 mm, wheel arch side −11.7 mm, tyre diameter −3.7 % : fit it with the original tyre size of Nissan Ariya (255/45R20), not that of Infiniti QX55.

Before fitting the wheels
An identical hub is not enough: offset, width and diameter change the position of the wheel, and larger calipers can touch a smaller wheel. Original wheels often use bolts or nuts with a specific seat: keep the fixings intended for the wheel, with the thread of Nissan Ariya (Ecrous - 12x1.25), tightened to the torque shown on its vehicle page. Finally, check that the size is among the approved fitments for your vehicle. This comparison is for guidance only: have the fitting approved by a professional.
