How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.


ANKUSI Engineering Expert Advice
On a vehicle this heavy, the wheel is a structural part before it is a styling part - it carries the load, the brake heat and the cornering forces all at once. A forged wheel buys back unsprung weight without giving up the load rating an SUV actually needs, which is the one number most cast aftermarket wheels quietly fall short on.
We publish the factory specification for the Buick GL8 III Facelift below. We have not yet been able to verify aftermarket flush or maximum-aggressive offsets for this exact variant against a source we trust, so we are not listing any - an invented offset is worse than no offset when a wheel has to clear a caliper.
Buick GL8 III Facelift OE Wheel Specs
The 2024 Buick GL8 III Facelift (SUV) uses a 5x120 bolt pattern with a 66.9mm center bore. Factory wheels are 17x7J F/R.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Buick GL8 III Facelift (2024) we drill the 5x120 pattern and cut the centre bore to 66.9mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Aftermarket Fitment Data — Coming Soon
Published aftermarket fitment for this exact variant is still thin, so we have not committed to a flush or maximum-aggressive figure. Our engineering team is still collecting verified data for this variant. In the meantime the factory specification above is accurate and is the safe reference point for ordering.
Need a wheel for this car now? Contact ANKUSI with your target diameter, width and offset and our engineers will confirm the correct forged spec against your brake package before anything is cut. You can also use our Offset & Backspacing Calculator to work through the numbers yourself.
Custom Forged Wheels for the Buick GL8 III Facelift (2024)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 5x120 pattern and the 66.9mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
