Toyota GR Corolla Tyre Size and Modified Fitment Guide Australia
Quick answer
The current Australian Toyota GR Corolla GTS uses 235/40R18 Yokohama ADVAN Apex V601 tyres on 18-inch Enkei alloy wheels. This applies to the current six-speed manual and eight-speed automatic GTS specification. The earlier two-seat Morizo Edition used a separate 245/40R18 Michelin Pilot Sport Cup 2 package and must not be treated as the current GTS specification. Confirm the complete load index and speed rating on the vehicle placard before ordering.
Australian OEM tyre size guide
| Australian version | Wheel | Factory tyre reference | Status and boundary |
|---|---|---|---|
| Current GTS manual | 18-inch Enkei alloy | 235/40R18 Yokohama ADVAN Apex V601 | Current grade; verify complete placard rating |
| Current GTS 8-speed automatic | 18-inch Enkei alloy | 235/40R18 Yokohama ADVAN Apex V601 | Current grade; verify complete placard rating |
| 2023 Morizo Edition | 18-inch forged alloy | 245/40R18 Michelin Pilot Sport Cup 2 | Earlier 25-unit, two-seat limited edition; not a GTS replacement size |

Normal Corolla Hatch and Sedan dimensions do not apply to the GR Corolla. Earlier GTS vehicles should still be checked by build date because Toyota has updated the model since its 2023 Australian launch.
Documented Autosport modified fitments
| Wheel package | Tyre package | Workshop evidence | Classification |
|---|---|---|---|
| BBS RIA 18x9.5 +22, 5x114.3 | Continental SportContact 7 245/40R18 | Documented GR Corolla installation | Modified; tyre load/speed suffix was not recorded in the case |
| WedsSport TC105X 18x9.5 +25, 5x114.3 | Yokohama ADVAN AD09 265/35R18 | Documented GR Corolla installation | Modified; tyre load/speed suffix was not recorded in the case |
These are evidence of specific workshop builds, not Toyota-approved universal upgrades. Before copying either package, verify wheel load rating, exact hub fit, offset, brake-caliper and guard clearance, suspension height, tyre shoulder shape, rolling diameter, speedometer effect, alignment, insurance and South Australian road legality. All four GR-FOUR tyres must remain suitably matched.
Specific tyre recommendations for placard-confirmed 235/40R18
| Use | Pattern and complete catalogue size | Fitment note |
|---|---|---|
| Factory-pattern direction | Yokohama ADVAN Sport V601 235/40R18 95Y | The current factory tyre family is ADVAN Apex V601; confirm the precise Australian placard suffix |
| Performance road | Continental MaxContact MC7 235/40R18 95Y XL | Road-performance candidate; verify rating |
| Performance road alternative | Michelin Pilot Sport 5 235/40R18 95Y XL | Daily performance candidate; verify rating |
| Focused road / occasional track direction | Yokohama ADVAN AD09 235/40R18 95W | Confirm speed-rating compliance and wet/cold-road trade-offs |
These are size-matched catalogue candidates, not stock or price claims. The placard's complete load and speed requirement takes priority.
GR-FOUR and performance checks
- Identify current GTS, earlier GTS or Morizo Edition before selecting a tyre.
- Keep all four tyres matched in size, construction, circumference and compatible tread depth.
- Check tyre pressures, balance, alignment and uneven wear.
- Do not present 245/40R18 or 265/35R18 workshop builds as the current GTS factory size.
- Track-focused tyres can trade wet, cold-road, noise and wear performance for dry grip.

Does the Morizo Edition use the same size?
No. The earlier Australian Morizo Edition used 245/40R18 Michelin Pilot Sport Cup 2 tyres and was a distinct limited two-seat model.
