Fitting wheels on a Buick LaCrosse

A Buick LaCrosse (2005–2009) uses a 5x115 PCD and a centre bore of 70.3 mm. Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.

  • PCD: 5x115 required. See all vehicles with 5x115.
  • Centre bore: the wheel must have a centre bore of 70.3 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 70.3 mm.
  • Offset: the original is ET40 to ET52. 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.
  • Tyres: original fitment is 225/60R16. For another size, check the diameter difference with the equivalence calculator (under 3 % recommended).

Vehicles with the same PCD and centre bore

Same 5x115 PCD and same 70.3 mm centre bore: wheels from these vehicles bolt on and centre on a Buick LaCrosse without rings. Offset, width, diameter and caliper clearance still need checking.

Does a Buick LaCrosse need a hub centric ring?

The centre bore (hub diameter) of a Buick LaCrosse is 70.3 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 Buick LaCrosse?

The recorded original offset is ET40 to ET52 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 Buick LaCrosse?

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 Buick LaCrosse?

With the same PCD (5x115) and the same centre bore (70.3 mm), these include: Buick Lucerne, Buick Rendezvous, Buick Park Avenue, Buick Century. Offset, width and rim diameter still need checking for each vehicle.
