Fitting wheels on a GMC Envoy

A GMC Envoy (2002–2009) uses a 6x127 PCD and a centre bore of 78.1 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

PCD: 6x127 required. See all vehicles with 6x127.
Centre bore: the wheel must have a centre bore of 78.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 78.1 mm.
Offset: the original is ET50. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
Fixings: thread Ecrous - 12x1.50. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.

Vehicles with the same PCD and centre bore

Same 6x127 PCD and same 78.1 mm centre bore: wheels from these vehicles bolt on and centre on a GMC Envoy without rings. Offset, width, diameter and caliper clearance still need checking.

Same PCD, different centre bore

These vehicles also use 6x127 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 78.1 mm, and will not fit if it is smaller.
