|---|---|---|---|---|
| 2011 | Mercury Grand Marquis | 5x114.3 | 70.5 mm | 17x7J |

Factory wheel sizes on the Mercury Grand Marquis
Across the 2 Mercury Grand Marquis trims with a documented factory wheel, the OE diameter is 17 inch, width 7J. A forged wheel that keeps the 5x114.3 bolt pattern and the 70.5 mm hub bore and matches the factory offset listed on the model page bolts on without spacers or hub rings. Going one inch up in diameter with a lower-profile tyre keeps the rolling circumference inside the usual 1.5% tolerance; every extra 0.5J of width moves the outer lip about 6 mm outward at the same offset, and each 5 mm less offset moves the whole wheel 5 mm outward.

Hub-Centric Rings for a 70.5 mm Center Bore
A wheel with a center bore larger than 70.5 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 71.6 mm | 71.6 → 70.5 mm |
| 72.6 mm | 72.6 → 70.5 mm |
| 73.1 mm | 73.1 → 70.5 mm |
| 74.1 mm | 74.1 → 70.5 mm |
ANKUSI forged wheels are bored to exactly 70.5 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Mercury Grand Marquis?
The Mercury Grand Marquis uses a 5x114.3 bolt pattern with a 70.5mm center bore across every Grand Marquis variant in our database (2 guides, 2003–2011).
What is the Mercury Grand Marquis center bore?
The hub-centric center bore is 70.5 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Mercury Grand Marquis years share the same wheel fitment?
The bolt pattern and center bore are the same across the years we cover, but OE wheel width and offset differ by trim, so check the exact model line before choosing an aftermarket size.
Which forged wheels fit the Mercury Grand Marquis?
Any wheel drilled 5x114.3 with a 70.5mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
