Toyota’s flagship — the only Japanese production car ever fitted with a V12, hand-finished, upholstered in wool because leather was considered too noisy — runs the same wheel as a Lexus LS400.
7JJx16, ET45, 5×114.3, 60.1 mm bore, M12x1.5. Unchanged for twenty years, from 1997 to 2017.
That is not an oversight. It is the entire philosophy of the car: nothing about a Century is intended to draw attention, least of all its wheels.
Section 1: OEM Wheel Specifications
| Model | Chassis Code | Years | Bolt Pattern | Hub Bore | Thread | OEM Wheel / Tyre |
|---|---|---|---|---|---|---|
| Century 5.0 V12 | GZG50 | 1997-2017 | 5×114.3 | 60.1 mm | M12x1.5 | 7JJx16 ET45 / 225/60R16 |
| Lexus LS400 (comparison) | UCF20 | 1994-2000 | 5×114.3 | 60.1 mm | M12x1.5 | 7Jx16 ET45 / 225/60R16 |
| Lexus LS430 (comparison) | UCF30 | 2000-2006 | 5×114.3 | 60.1 mm | M12x1.5 | 7.5Jx17 ET45 |
The G50 Century shares its bolt pattern, hub bore, thread and offset with the LS400 and LS430. Wheels interchange directly between all three.

Section 3: The Restraint Is the Point
A Century is 5,270 mm long and weighs around 2,000 kg. It is wider than an LS400 and taller. And Toyota put a 16-inch wheel on it — with a full-diameter hubcap on most cars, because an exposed alloy would have been ostentatious.
For an owner, this creates a straightforward choice with no middle ground:
- Leave it alone. A correct, unmodified Century on factory wheels is increasingly rare and increasingly valued. The 16-inch wheel is part of what the car is.
- Commit to VIP. The alternative tradition — large-diameter deep-lip multi-piece wheels, air suspension, negative camber — is equally established and equally Japanese.
There is very little appetite for anything in between, and that is worth knowing before you spend money.

Section 4: What Fits
The Century uses Toyota’s most common combination and is therefore mechanically easy:
- Lexus LS400, LS430, SC430, Soarer, Chaser, Supra, IS wheels all fit directly. See our LS400 guide and LS430 guide.
- Nissan wheels (66.1 mm) fit with a 66.1–60.1 hub-centric ring.
- Evo and RX-7 FD wheels (67.1 mm) fit with rings.
- The LS460 does not share this fitment — it moved to 5×120 with M14x1.5. See our LS460 guide.
Section 5: If You Go Large
Realistic steps, in order:
- 18×8 ET40 with 235/50R18 — a genuinely tasteful upgrade. Keeps the rolling diameter close to factory, fills the arch, requires nothing. Arguably the best-value change you can make.
- 19×8.5 ET35 with 245/40R19 — more presence, still no body work at standard ride height.
- 20×9.5 ET15 with 245/30R20 — full VIP. Air suspension, camber, rolled or pulled arches.
Two cautions specific to this car.
First, weight. A Century is a two-tonne car and large multi-piece wheels are heavy. A 20-inch three-piece with a wide lip can exceed 15 kg per corner — check the published load rating and look for the JWL and VIA stamps on any used Japanese wheel.
Second, ride quality. The Century’s entire engineering brief was isolation. Going from a 60-series sidewall to a 30-series undoes a substantial part of what makes the car what it is. That may be an acceptable trade — but it should be a deliberate one.

Buying Wheels for Your Century
Mechanically, nothing about the Century is difficult: 5×114.3, 60.1 mm, M12x1.5, and the widest parts pool in Japan. The only real decision is whether you are keeping the car as Toyota intended it, or joining the other tradition.
