Fitting wheels on a Chevrolet G20 Van

A Chevrolet G20 Van (1971–1996) uses a 5x127 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: 5x127 required. See all vehicles with 5x127.
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 ET19. 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 - 1/2 - 20 UN, tightened to 140 Nm. 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 5x127 PCD and same 78.1 mm centre bore: wheels from these vehicles bolt on and centre on a Chevrolet G20 Van without rings. Offset, width, diameter and caliper clearance still need checking.
