Mazda Miata bolt pattern by generation (NA, NB, NC, ND): 4x100 or 5x114.3, hub bore, lug nuts and torque
Published · Updated
What is the bolt pattern on each Miata generation?
Short answer: It depends on the generation. The NA (1990-97), NB (1999-2005) and ND (2016+) all use 4x100 with a 54.1 mm hub bore. The NC (2006-15) is the odd one out: 5x114.3 with a 67.1 mm hub. Every generation uses M12x1.5 lug nuts with a conical (60-degree) seat. Mazda's owner's manuals give 88-118 N·m (65-87 ft-lbf) for the NC and 108-147 N·m (80-108 ft-lbf) for the 2016 ND. NC wheels do not bolt onto any other Miata, and NA/NB/ND wheels do not bolt onto an NC.
Miata wheel specs by generation
Facts as of 2026-11-10, US model years. Each row is restated from the generation's wheel spec and the linked answer pages, with their sources listed below.
| Generation | Bolt pattern | Hub bore | Lug thread and seat | Lug nut torque |
|---|---|---|---|---|
| NA (1990-1997) | 4x100 | 54.1 mm | M12x1.5, 60-degree conical | 86 ft-lb in a wheel guide (Mazda figure not read) |
| NB (1999-2005, incl. Mazdaspeed) | 4x100 | 54.1 mm | M12x1.5, 60-degree conical | 86 ft-lb in a wheel guide (Mazda figure not read) |
| NC (2006-2015) | 5x114.3 | 67.1 mm | M12x1.5, 60-degree taper | 88-118 N·m (65-87 ft-lbf), 2006 and 2009 owner's manuals |
| ND (2016+, incl. RF) | 4x100 | 54.1 mm | M12x1.5, conical seat | 108-147 N·m (80-108 ft-lbf), 2016 owner's manual |
NA and NB (1990-2005): 4x100
Two rimlist wheel guides (NA and NB, both re-read on 2026-11-10) list the same hub for every first- and second-generation car: 4x100, a 54.1 mm center bore and M12x1.5 studs, with factory wheels using a 60-degree conical seat. Both give 86 ft-lb for the lug nuts. We have not read a Mazda manual for 1990-2005 cars, so treat that torque as the guide's figure and check the owner's manual for your year.
Factory NA wheels are 14x5.5 or 14x6 at +45 (15x6 +45 on some special editions). NB wheels run from 14x6 to 17x7 depending on year and trim, mostly at +40. Sizes and offsets by year are on the Miata NA/NB wheel fitment guide and the linked answer pages.
NC (2006-2015): 5x114.3, the odd one out
The NC switched to five lugs. Its hub is 5x114.3 with a 67.1 mm bore, and its lug nuts are M12x1.5 with a 60-degree taper seat. Mazda's 2006 and 2009 owner's manuals (the 2006 one re-read on 2026-11-10) give 88-118 N·m, which is 65-87 ft-lbf. Grip Theory, a wheel maker, quotes 108 N·m (80 ft-lb), which sits inside Mazda's range.
Because the bolt pattern differs, NC wheels do not bolt onto an NA, NB or ND, and NA, NB or ND wheels do not bolt onto an NC. The guides we read do not recommend adapters; shop for wheels made for the NC's 5x114.3 pattern. Aftermarket M12x1.5 60-degree lug nuts sold for the NC need a deep 19 mm socket according to the vendor.
ND (2016 on): back to 4x100
The ND returned to 4x100 with a 54.1 mm hub, M12x1.5 lug nuts and a conical seat, per Miatafy's ND fitment guide (re-read 2026-11-10); Flyin' Miata sells its 54.1 mm centering rings for the ND and RF as well as the NA and NB. The 2016 owner's manual gives 108-147 N·m (80-108 ft-lbf), higher than the NC range. We read only the 2016 manual, so the torque is confirmed for that year; check yours for later cars.
Sharing the pattern does not mean every older Miata wheel fits an ND. The US 2.0 L ND's front brakes rule out most 15-inch wheels unless the smaller global 1.5 L brakes or compact calipers are fitted, and no source we read has checked NB 16-inch wheels on an ND. ND wheels do bolt onto an NA or NB, though their +45 offset and taller tires look awkward and read the speedometer low.
Hub-centric rings and lug nuts
- Most aftermarket 4x100 wheels have a 67.1 or 73.1 mm bore. Rings sized from that bore down to 54.1 mm center them on an NA, NB or ND hub.
- Sources differ on how much rings matter. A wheel guide says they prevent vibration and should be used; Flyin' Miata says a 67.1 mm bore wheel centers itself on the tapered lug nuts once torqued, so rings make installation easier rather than being a necessity. Aluminum rings are suggested over plastic for track use.
- Match the lug nut seat to the wheel. The guides warn against ball-seat (common on Honda) or flat-washer nuts on conical-seat wheels.
- Longer studs: the NC and ND take the ARP 0.507 in knurl extended stud; the vendor says to press studs in rather than pull them through with a lug nut.
- Never oil or grease lug nuts or studs. Mazda's NC and ND owner's manuals warn against it, and the ND manual says the nuts could loosen while driving.
What we could not confirm
A Mazda lug nut torque figure for the NA and NB; the ND torque for model years other than 2016; and whether every ND year and trim (including the 2024 refresh) keeps exactly the same stud and nut spec. We will add these when we have read a Mazda source for them.

FAQ
What is the ND Miata lug pattern?
4x100, with a 54.1 mm hub bore and M12x1.5 conical-seat lug nuts. Mazda's 2016 owner's manual gives 108-147 N·m (80-108 ft-lbf) lug nut torque. It is the same pattern as the NA and NB, not the NC.
What is the NC Miata bolt pattern?
5x114.3 with a 67.1 mm hub bore and M12x1.5 lug nuts with a 60-degree taper seat. The 2006 and 2009 owner's manuals give 88-118 N·m (65-87 ft-lbf). It is the only Miata generation with five lugs.
What is the NA and NB Miata bolt pattern?
4x100 on every 1990-2005 car, including the Mazdaspeed, with a 54.1 mm center bore and M12x1.5 studs. Wheel guides give 86 ft-lb for the lug nuts; check your owner's manual.
Do NC Miata wheels fit an ND, NA or NB?
No. The NC is 5x114.3 and the others are 4x100, so NC wheels do not bolt on, and the reverse is also true.
Do I need hub-centric rings on a Miata?
Most aftermarket 4x100 wheels have a larger bore than the 54.1 mm hub. A wheel guide recommends rings to avoid vibration; Flyin' Miata calls them a convenience because the tapered lug nuts center the wheel. Factory Miata wheels are already hub-centric, and the Flyin' Miata rings do not fit them.
