The GR Corolla is the car Toyota built to be a hot hatch with a rally car’s drivetrain, and its wheel specification is easy to state and easy to get slightly wrong. This guide sets out what Toyota’s own documents say and what two independent Japanese wheel databases add, and it is explicit about the gaps.
For American readers there is a complication worth saying first: Toyota also sold a GR Corolla in the United States, so the car this guide covers is the Japan-market one (chassis code GZEA14H), and we did not verify the US-market wheel specification. If you are buying a Japanese-market car or a Japanese-market wheel, read on.
The Short Version
- The Japan-market RZ runs 18×8.5J +30 on 235/40R18 tyres. Toyota’s 2025 specification sheet states the 18-inch, 8.5J, +30 forged wheel and the 235/40R18 Yokohama ADVAN APEX V601. Toyota’s earlier sheet states the 8.5J forged BBS wheel but not the offset.
- The bolt pattern is 5×114.3. Toyota’s documents do not state it. Spec Tank and Cars Japan both list 114.3 / 5, and both list a 60 mm hub bore.
- The Morizo Edition wears a wider tyre. Toyota’s 2022 announcement lists 245/40R18 Michelin Pilot Sport Cup 2 on 18-inch BBS forged wheels with a TOYOTA GAZOO Racing logo. Toyota did not state the rim width or offset in that announcement; Cars Japan lists 18×8.5J +30.
- The 8-speed automatic car uses the same wheel and tyre in the databases we read.
The Grades and What They Wear
Toyota unveiled the Japanese-specification car in June 2022 as two models. The RZ is the five-seat car with a 1.6-litre turbocharged three-cylinder engine rated at 304 PS, a six-speed manual and the GR-FOUR four-wheel-drive system; Toyota lists it at 1,470 kg. The Morizo Edition is the two-seat version, listed at 1,440 kg, with the same engine and a higher torque figure. Toyota’s later specification sheet also lists an eight-speed automatic, which Toyota calls GR-DAT, alongside the manual.
Factory Specification
| Grade | Chassis | Period (as databases list it) | Wheel | Tyre | PCD / Holes |
|---|---|---|---|---|---|
| RZ, 6MT | 4BA-GZEA14H | 2022.12–2025.03 | 18×8.5J +30 | 235/40R18 | 114.3 / 5 |
| RZ, 8AT (GR-DAT) | 4BA-GZEA14H | 2025.03–2025.11 | 18×8.5J +30 | 235/40R18 | 114.3 / 5 |
| Morizo Edition | 4BA-GZEA14H | 2022.12–2023.07 | 18×8.5J +30 (Cars Japan only) | 245/40R18 | 114.3 / 5 |
The database period labels are the databases’ own, and the sites split the model run at slightly different dates. Treat them as approximate and check the build plate of a specific car.
What This Means When Shopping
The +30 offset is the figure to watch. A wheel built for a +55 car at the same 5×114.3, such as the Subaru WRX S4, would sit about 25 mm further inboard on this car; that is arithmetic from the offset difference, not a fitment result. Whether a given wheel clears the brakes, struts and arches on this car is not something the databases tell us.
Tyre size is the other detail. The RZ’s 235/40R18 has a sidewall of about 94 mm (235 × 0.40) and an overall diameter of about 645 mm; the Morizo Edition’s 245/40R18 works out to about 98 mm and about 653 mm. Both figures are arithmetic from the printed size, not measurements.
The factory wheel is a BBS forged piece, so a replacement set of the original design is a forged-wheel purchase. If you are replacing it with something else, the wheel needs to be 5×114.3, and its centre bore needs to be at least 60 mm, with a hub ring to make up any difference. For how to measure the hub bore yourself, see our hub bore reference below.
Importing
The databases list the first Japan-market GR Corolla from December 2022. In the US, the 25-year import exemption (49 CFR 591.5(i)) applies to a vehicle that is 25 or more years old, counted from the date of manufacture. On that reading no Japan-market GR Corolla can qualify before late 2047, and we have not verified the month the first cars were built. We did not check the import rules of other countries for this guide.
What We Could Not Verify
- The Morizo Edition’s rim width and offset. Toyota’s announcement gives the tyre and the 18-inch size but not the width or offset. The 8.5J +30 figure comes from one database, Cars Japan, and we found no second source.
- The factory offset on the earliest cars. Toyota’s 2023 specification sheet states 8.5J but not the offset. The +30 figure for the RZ is stated in Toyota’s 2025 sheet and agrees with both databases, but we read the earlier sheet only for the width.
- The bolt pattern and hub bore from Toyota itself. Neither is stated in the Toyota documents we read. The 114.3 / 5 and 60 mm figures rest on the two databases.
- A conflicting wheel size on one catalogue page. One used-car catalogue page for the RZ was summarised by our tools as listing 20-inch wheels. Toyota’s own documents say 18-inch, so we treated it as an error, but we did not resolve where it came from.
- Models after November 2025. Catalogues list newer entries; we did not check their wheel specification.
- The US-market GR Corolla, which we did not verify and which may differ.
- Wheel weight, nut seat type, and real-world clearance of any aftermarket wheel.
