Fitting wheels on a Chevrolet Avalanche

A Chevrolet Avalanche (2001–2006) 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, tightened to 190 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
  • Tyres: original fitment is 265/70R17. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

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 Avalanche without rings. Offset, width, diameter and caliper clearance still need checking.

Frequently asked questions

What is the PCD of a Chevrolet Avalanche?

A Chevrolet Avalanche (2001–2006) has a PCD of 6x139.7: 6 studs or bolts spaced around a circle 139.7 mm in diameter.

Does a Chevrolet Avalanche need a hub centric ring?

The centre bore (hub diameter) of a Chevrolet Avalanche is 78.1 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.

What offset (ET) for a Chevrolet Avalanche?

The recorded original offset is ET31 depending on the version and wheel size. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.

What tightening torque for the wheels of a Chevrolet Avalanche?

The specified tightening torque is 190 Nm for Ecrous - 14x1.50 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.

Which vehicles have the same PCD as a Chevrolet Avalanche?

With the same PCD (6x139.7) and the same centre bore (78.1 mm), these include: Chevrolet Astro 4WD, Chevrolet Silverado, Chevrolet Tahoe, Chevrolet C,K. Offset, width and rim diameter still need checking for each vehicle.
