Mercedes-Benz SL wheel specs by year and trim
Factory wheel sizes on the Mercedes-Benz SL
Across the 48 Mercedes-Benz SL trims with a documented factory wheel, the OE diameter is 16-21 inch, width 8-10J. A forged wheel that keeps the 5x112 bolt pattern and the 66.6 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.

Vehicles With the Same Hub as the Mercedes-Benz SL (5x112, 66.6 mm Bore)
In our database, 368 other vehicle entries from 20 makes use exactly the same 5x112 bolt pattern and 66.6 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x112 is used by 21.9% of the vehicle entries in our database (1,403 of 6,396); 58.6% of those also use a 66.6 mm center bore.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 19x9.5J | ET59 | 7.57 in (192 mm) | — | — |
| Flush | 20x1J | ET28 | 6.60 in (168 mm) | −25 mm | +37 mm |
| Maximum | 21x10.5J | ET25 | 6.73 in (171 mm) | −21 mm | +47 mm |
Hub-Centric Rings for a 66.6 mm Center Bore
A wheel with a center bore larger than 66.6 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 67.1 mm | 67.1 → 66.6 mm |
| 70.1 mm | 70.1 → 66.6 mm |
| 70.5 mm | 70.5 → 66.6 mm |
| 71.6 mm | 71.6 → 66.6 mm |
| 73.1 mm | 73.1 → 66.6 mm |
ANKUSI forged wheels are bored to exactly 66.6 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Mercedes-Benz SL?
The Mercedes-Benz SL uses a 5x112 bolt pattern with a 66.6mm center bore across every SL variant in our database (53 guides, 1995–2025).
What is the Mercedes-Benz SL center bore?
The hub-centric center bore is 66.6 mm. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Mercedes-Benz SL 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 Mercedes-Benz SL?
Any wheel drilled 5x112 with a 66.6mm 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.
