Toyota LandCruiser 300 Tyre Size Guide Australia
Quick answer
The current Australian LC300 uses three factory tyre sizes: 245/75R17 on GX, 265/65R18 on GXL, VX, Sahara and GR Sport, and 265/55R20 on Sahara ZX. Toyota Australia's September 2026 specification table is the source. Confirm the individual vehicle placard for load index and speed rating before ordering, particularly where diesel and Performance Hybrid versions coexist.

Verified modified LC300 fitment
| Vehicle | Wheel | Tyre | Status |
|---|---|---|---|
| LC300 GR Sport workshop case | ROH Onyx 18x9 +35 | BFGoodrich All-Terrain T/A KO3 285/65R18 | Documented Autosport Tyre World modified fitment |
285/65R18 is not the factory tyre size in Toyota's current Australian table. It is a larger modified setup. Before copying it, confirm wheel load rating, wheel width and offset, brake and guard clearance, suspension height, rolling diameter, speedometer effect, spare-wheel compatibility, alignment and South Australian legality.
Tyre recommendations for factory 265/65R18 vehicles
| Use | Pattern and complete catalogue size | Fitment note |
|---|---|---|
| Balanced all-terrain touring | Continental CrossContact A/T2 265/65R18 122/119S | Confirm the LT/load and speed specification against the placard and intended load |
| Road-oriented all-terrain | Yokohama GEOLANDAR G015 265/65R18 114H | Suitable candidate where the full rating meets the individual vehicle requirement |
| Mixed touring and off-road | Toyo Open Country A/T III 265/65R18 114H or 114T | Choose the correct rating only after checking the placard and use |
| More aggressive all-terrain | BFGoodrich KO3 265/65R18 117/114S | Check construction, load, speed and ride trade-offs |
| Documented modified setup | BFGoodrich KO3 285/65R18 on ROH Onyx 18x9 +35 | Modified fitment only; requires full vehicle and legal inspection |
These are fitment candidates, not current-stock or universal-fitment claims. GX 245/75R17 and Sahara ZX 265/55R20 owners should use their exact placard specification and available matching catalogue options rather than substituting an 18-inch recommendation.
LC300 checks before fitting
- Confirm GX, GXL, VX, Sahara, Sahara ZX or GR Sport, plus diesel or Performance Hybrid.
- Match complete tyre size, load index, speed rating and construction to the placard.
- Keep all four tyres appropriately matched for the full-time 4WD system and check the spare.
- Account for passengers, accessories, towing load and axle loading.
- For modified wheels, verify PCD, centre bore, width, offset, load rating and brake clearance from the wheel documentation.
- Complete balancing and four-wheel alignment after a wheel or tyre-size change.
