Wheels from Renault Captur II on Opel Vivaro: compatible?

No, the centre bore is too small

Same 5x114.3 PCD, but the centre bore of the wheels from Renault Captur II (66.1 mm) is smaller than the hub of Opel Vivaro (71.1 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 Opel Vivaro (M14x1.50), 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.
