The Mark X is what Toyota built after it stopped building the Chaser. It arrived on 9 November 2004 as the replacement for the whole Mark II family — Mark II, Chaser, Cresta, Verossa — and it ran until December 2019.
If you are in the United States, one fact matters before all the others: the Mark X is not importable under the 25-year rule until November 2029. Nothing in this guide changes that. If you are in Japan, the UK, Australia or New Zealand, read on.
The Short Version
- 5×114.3 on a 60.1 mm bore, M12×1.5 — every Mark X, every grade, both generations.
- Same as the Chaser JZX100 and the contemporary Crown. The X120 was built on the twelfth-generation Crown platform.
- The chassis code tells you the engine. GRX120/130 = 2.5, GRX121 = 3.0, GRX133 = 3.5, and the 5 codes are all-wheel drive.
- Offset moved between generations — roughly +50 on the X120, +40 on the X130.
- The GRMN ran staggered 19-inch wheels. The only Mark X that did from the factory.
Reading the Chassis Code
| Code | Generation | Engine | Drive |
|---|---|---|---|
| GRX120 | X120, 2004–2009 | 2.5 4GR-FSE, 215 PS | RWD |
| GRX121 | X120 | 3.0 3GR-FSE, 256 PS | RWD |
| GRX125 | X120 | 2.5 4GR-FSE | AWD |
| GRX130 | X130, 2009–2019 | 2.5 4GR-FSE | RWD |
| GRX133 | X130 | 3.5 2GR-FSE, 318 PS | RWD |
| GRX135 | X130 | 2.5 4GR-FSE | AWD |
The pattern is simple once you see it: the last digit is the drivetrain — 0 and 3 are rear-wheel drive, 5 is all-wheel drive — and the middle digit steps up with displacement.
The X130 ran a very long time with two facelifts, in 2012 and 2016. A 2010 GRX130 and a 2018 GRX130 are the same chassis code and quite different cars.
Factory Wheel and Tyre
| Generation | Grade | Wheel | Offset | Tyre |
|---|---|---|---|---|
| X120 | 2.5 base | 7J×16 | +50 | 215/60R16 95H |
| X120 | 2.5 G package | 8JJ×18 | +50 | 225/45ZR18 91W |
| X130 (2009–12) | 2.5 base | 7J×16 | +40 | 215/60R16 95H |
| X130 (2009–12) | 2.5, 18″ | 8J×18 | +45 | 235/45ZR18 94W |
| X130 AWD | GRX135 | 7J×16 | +40 | 215/60R16 95H |
| X130 (2012–16) | 2.5, 19″ | 8J×19 | +40 | 235/40ZR19 92Y |
| X130 | 350S (GRX133) | not itemised | +43 to +47 | 18″ 94W / 19″ 92Y |
| X130 | 350S G’s | 8J×19 | +40 | not confirmed |
| X130 | GRMN | 19×8J front / 19×9J rear | +40 f / +50 r | 235/40ZR19 f / 255/35ZR19 r |
The offset moved between generations. X120 sits around +50; X130 around +40 to +45. That is a meaningful shift — roughly 10 mm of wheel position — and it means X120 wheels on an X130 will sit further in than the car was designed for, and X130 wheels on an X120 will sit further out.
They will bolt on. That is not the same as fitting.
The GRMN
Built from December 2014, manual only, with the 2GR-FSE and a Getrag six-speed. It is the only Mark X that left the factory on staggered wheels: 19×8J at +40 in front, 19×9J at +50 behind.
We should flag how we got that. It comes from two Japanese wheel-fitment databases that agree with each other, not from a Toyota press document. A lower-quality guide site gives 19×8.5 at +55 instead; we discarded it as inconsistent with both databases, but you should treat the figure as well-corroborated rather than certain.
Interchange With Chaser and Crown
Bolt pattern and bore are shared: 5×114.3 and 60.1 mm across Mark X, Chaser JZX100 and the Crown of the same era. The X120 was built on the twelfth-generation Crown platform, so this is a family relationship rather than a coincidence.
But interchange also depends on offset and hub geometry, and we did not verify those wheel by wheel. The pattern matching means the wheel will bolt on; it does not mean it will sit where you want. Check the offset of the specific wheel against the specific car.
Import Status
The Mark X launched 9 November 2004. Under the US 25-year rule, counted from the build month, the earliest cars become eligible in November 2029.
As of mid-2026 no Mark X is importable to the United States for road use. If someone offers to import you one now, ask them under what category — because it will not be that one.
What We Could Not Verify
- Whether the AWD cars (GRX125, GRX135) run a different offset from their rear-drive siblings. The databases mirror the RWD data rather than itemising AWD.
- Factory rim width for the GRX121 3.0 — tyre codes only.
- Wheel specification for the final 350RDS and 350RDS GR Sport (2016–2019) beyond “19 inch.”
- A Toyota document confirming the GRMN staggered fitment. Two Japanese databases agree; Toyota’s own material was not found.
- True cross-fit with Crown and Chaser beyond pattern and bore.

Getting Mark X Wheels From Japan
This is a domestic-market car, so the good used wheels for it are in Japan and stay in Japan. Tell us the chassis code and the year — the X130 ran a decade and the right answer for a 2010 car is not the right answer for a 2018 one. The Request page is the place.
