Factory wheel sizes on the Mazda MX-5
Across the 8 Mazda MX-5 trims with a documented factory wheel, the OE diameter is 14-17 inch, width 5.5-7J and offset ET45-55. A forged wheel that keeps the bolt pattern and hub bore of your generation (see the table above) and stays inside that offset range bolts on without spacers or hub rings. The offset spread between trims is 10 mm, so read the year-by-year row for your exact car before choosing a width. 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 Mazda MX-5 (4x100, 54.1 mm Bore)
In our database, 121 other vehicle entries from 19 makes use exactly the same 4x100 bolt pattern and 54.1 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.
4x100 is used by 6.7% of the vehicle entries in our database (426 of 6,396); 32.9% of those also use a 54.1 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) | 16x6.5J | ET45 | 5.52 in (140 mm) | — | — |
| Flush | 17x7.5J | ET38 | 5.75 in (146 mm) | +6 mm | +20 mm |
| Maximum | 17x8J | ET35 | 5.88 in (149 mm) | +9 mm | +29 mm |
Hub-Centric Rings for a 54.1 mm Center Bore
A wheel with a center bore larger than 54.1 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 56.1 mm | 56.1 → 54.1 mm |
| 57.1 mm | 57.1 → 54.1 mm |
| 60.1 mm | 60.1 → 54.1 mm |
| 63.4 mm | 63.4 → 54.1 mm |
| 73.1 mm | 73.1 → 54.1 mm |
ANKUSI forged wheels are bored to exactly 54.1 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Mazda MX-5?
The Mazda MX-5 uses a 4x100 bolt pattern on most variants we cover with a 54.1mm center bore. Other generations use 5x114.3 / 67.1mm (2013–2014). Always check the exact year and trim before ordering.
What is the Mazda MX-5 center bore?
The hub-centric center bore is 54.1 mm on the most common generation; see the table for variants. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Mazda MX-5 years share the same wheel fitment?
No. The bolt pattern or center bore changed between generations, so wheels are not interchangeable across all years. Use the year-by-year table on this page to pick the right specification.
Which forged wheels fit the Mazda MX-5?
Any wheel drilled 4x100 with a 54.1mm 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.
