Wheels from Alfa Romeo Giulietta on Jeep Cherokee: compatible?

No, the centre bore is too small

Same 5x110 PCD, but the centre bore of the wheels from Alfa Romeo Giulietta (65.1 mm) is smaller than the hub of Jeep Cherokee (71.6 mm): they will not fit without being re-bored by a professional.

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 Jeep Cherokee (M12x1.25), 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.
