A Chevrolet Trailblazer (2001–2005) 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.
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, tightened to 135 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 6x127 PCD and same 78.1 mm centre bore: wheels from these vehicles bolt on and centre on a Chevrolet Trailblazer without rings. Offset, width, diameter and caliper clearance still need checking.
Will wheels from another vehicle fit your Trailblazer?
Choose the vehicle the wheels come from: we compare the hub, then each original wheel to the millimetre.
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.
A Chevrolet Trailblazer (2001–2005) has a PCD of 6x127: 6 studs or bolts spaced around a circle 127 mm in diameter.
Does a Chevrolet Trailblazer need a hub centric ring?
The centre bore (hub diameter) of a Chevrolet Trailblazer 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 Trailblazer?
The recorded original offset is ET50. 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 Trailblazer?
The specified tightening torque is 135 Nm for Ecrous - 12x1.50 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 Trailblazer?
With the same PCD (6x127) and the same centre bore (78.1 mm), these include: Chevrolet Envoy, Saab 9-7X, Buick Rainier, GMC Envoy. Offset, width and rim diameter still need checking for each vehicle.
