Fitting wheels on a Chevrolet C,K

A Chevrolet C,K (1988–2010) uses a 6x139.7 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: 6x139.7 required. See all vehicles with 6x139.7.
  • 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 ET31. 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 - 14x1.50. 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 6x139.7 PCD and same 78.1 mm centre bore: wheels from these vehicles bolt on and centre on a Chevrolet C,K without rings. Offset, width, diameter and caliper clearance still need checking.
