TL;DR: The Australian Toyota LandCruiser 300 Series runs 245/75R17 on the GX, 265/65R18 on GXL, VX, Sahara and GR Sport, and 265/55R20 on the Sahara ZX. Wheels are 6×139.7 PCD with a 95.1 mm centre bore and roughly +60 mm offset. Every grade carries a full-size spare and tows 3,500 kg braked. Always set pressures from your door placard.
The LandCruiser 300 Series is one of the most capable large 4WD wagons sold in Australia, and it is bought to tow, tour and carry weight. That makes its tyres and wheels load-critical kit, not a styling choice. This guide pulls together the delivered sizes, wheel specs, spare, pressures and replacement costs for the current LC300 range, with every figure framed as a 2026 guide to confirm against your own vehicle.

What tyre sizes does the LandCruiser 300 use?
The LC300 does not use one size across the range. The entry GX rides on 17-inch steel wheels with a taller, tougher tyre, the mid grades sit on 18-inch alloys, and the flagship Sahara ZX moves to 20-inch rubber with a lower profile. Fitment is tied to the grade, so the first step is always to read what is actually on your vehicle.
| Grade | Wheel | Tyre size |
|---|---|---|
| GX | 17×8.0 steel | 245/75R17 |
| GXL | 18-inch alloy | 265/65R18 |
| VX | 18-inch alloy | 265/65R18 |
| Sahara | 18-inch alloy | 265/65R18 |
| GR Sport | 18-inch black alloy | 265/65R18 |
| Sahara ZX | 20-inch alloy | 265/55R20 |
Those three diameters are close in overall rolling diameter by design, so speedo accuracy and gearing stay consistent across the range. The 245/75R17 on the GX is the tourer’s favourite because the taller sidewall soaks up corrugations and sharp rock, and the 17-inch rim leaves more room for serious all-terrain and mud-terrain tread. If you want to understand why the numbers on the sidewall matter, our guide on how to read a tyre sidewall breaks every digit down, and aspect ratio explained covers why the ZX’s lower-profile 20s ride firmer.
What are the LC300 wheel specs (PCD, bore, offset, torque)?
Every LC300 shares the heavy-duty six-stud wheel pattern used across Toyota’s big 4WDs. The critical numbers for anyone buying aftermarket wheels are below.
| Spec | Figure (2026 guide) |
|---|---|
| Bolt pattern (PCD) | 6×139.7 mm |
| Centre bore | 95.1 mm |
| Factory offset (ET) | approx. +60 mm (OE) |
| Wheel nut torque | approx. 140 Nm |
| Studs | 6 |
The 6×139.7 pattern is shared with the HiLux, Prado, Ford Ranger, Isuzu D-Max and other six-stud utes and wagons, but sharing a bolt pattern does not make a wheel a straight swap. The LC300’s 95.1 mm centre bore and roughly +60 mm offset still have to match, or the wheel will not sit true. If a wheel’s bore is larger than the hub you need hub-centric rings, which our explainer on hub-centric vs lug-centric fitment covers, along with centre bore explained and wheel offset and backspacing. If you are not sure how to confirm your own pattern, start with bolt pattern and PCD explained.
Torque matters on a vehicle this heavy. Doing wheel nuts up with a rattle gun is the quickest way to warp a brake disc or over-stress a stud, so a torque wrench is not optional — see wheel nut torque and why you should re-torque after fitting. Deciding between the GX’s steels and the alloys on higher grades for touring? Alloy vs steel wheels lays out the honest trade-off.
Does the LandCruiser 300 have a full-size spare?
Yes. Unlike most monocoque SUVs, every LC300 grade carries a full-size spare slung under the rear of the vehicle. On the GX that is a matching steel wheel; on the alloy-equipped grades the spare is typically a full-size steel or alloy that matches the rolling diameter. A full-size spare is a genuine advantage for remote travel because you can rotate it into service indefinitely rather than limping on a space-saver.
Two things catch LC300 owners out. First, the spare’s pressure is easy to forget — a soft spare is useless when you finally need it, so check it when you do the other five tyres (spare tyre pressure). Second, an under-slung spare winch and cradle can seize with mud and salt, so exercise it occasionally. If you fit aftermarket all-terrains, remember the spare should match — our piece on whether you need a matching all-terrain spare explains why. The LC300 is one of the few remaining large vehicles that still ships this way; see which Australian new cars still come with a full-size spare.
What tyre pressures should an LC300 run?
Set LC300 pressures from the placard in the driver’s door jamb, not from a forum figure or the maximum printed on the sidewall. The placard gives the cold pressures Toyota specifies for your exact grade and tyre size, and it usually lists a higher rear figure for loaded running. As a general guide, large 4WD wagons sit around the low-to-mid 200s in kPa (roughly 32–40 psi) unladen, rising when you load up or tow, but the placard is the number that counts.
Because the LC300 is bought to carry and tow, you will be adjusting pressures far more than a car owner does. When you add the weight of a full tank, long-range fuel, water, drawers and a loaded roof, the rears in particular need more air to keep the tyre’s shape under load. Our guides on placard pressure vs sidewall maximum and tyre pressures for towing a caravan walk through the adjustments. Off the bitumen you drop pressures to suit the surface — see correct pressures for sand and pressures for corrugated dirt roads — then reinflate before you return to sealed roads. Summer heat also pushes pressures up, which is normal; check them cold (cold vs hot tyre pressure).
Best replacement tyres for the LandCruiser 300
The right LC300 tyre depends entirely on where you drive. The honest split is simple: the more dirt and remote travel you do, the more you lean towards a genuine light-truck-construction all-terrain; the more highway and towing you do, the more a quiet, long-wearing highway-terrain makes sense.
- Mostly highway and towing: a premium highway-terrain in the correct load rating prioritises quiet, economy and tread life. See best towing tyres for a large seven-seat SUV.
- 80% road, 20% dirt: an all-terrain is the sweet spot — best tyres for mixed 80/20 driving.
- Serious remote and rock: an LT-construction all-terrain or mud-terrain with a tough three-ply sidewall. Our all-terrain vs highway-terrain vs mud-terrain comparison and do you need LT-construction tyres are the place to start.
Whatever you choose, do not drop below the placard load index — on a 3.5-tonne tow vehicle that is a safety and legal issue, not a suggestion (load index chart, load ratings after a GVM upgrade). The difference between a P-metric and an LT tyre matters here too: LT vs P-metric tyres.
How much do LandCruiser 300 tyres cost?
LC300 tyres are large, heavy and load-rated, so they cost more than passenger rubber. As a 2026 guide, expect a wide spread depending on grade and tyre type, with the 20-inch Sahara ZX fitment at the top end and quality all-terrains for the 17s and 18s in the mid range. A full set of five (so the spare matches) is the realistic budget for tourers. Prices move constantly, so get a live quote rather than trusting a number online — our piece on how much 4WD tyres cost compared to passenger tyres explains the premium, and cost per kilometre is the fairer way to compare a cheap tyre against a long-wearing one.
For context on where the LC300 sits in the range, the 2025 line-up listed the GX from $96,991, GXL $108,791, VX $120,991, Sahara $138,191, GR Sport $144,791 and Sahara ZX $145,791 before on-road costs, per CarExpert. Tyres are a small fraction of that, but on a vehicle you rely on in remote country they are the wrong place to cut corners.
Can you upsize the LC300 to 33s or bigger?
Many owners go up a size for clearance and a tougher tyre, most commonly to a 285/70R17 (around 33 inches) on the GX-style 17-inch wheel. This is popular and well supported, but it is not consequence-free. Bigger tyres change your effective gearing and throw your speedo out, can foul guards and suspension at full lock or articulation without a lift, and — critically on a 3,500 kg tow vehicle — must still meet the placard load rating. Rolling-diameter increases are also regulated, with limits that vary by state and get more generous with a lift and engineering. Confirm before you buy.
Start with what is rolling diameter, then do you need to recalibrate your speedo after upsizing and the fuel-economy cost of 33s. If a lift is part of the plan you will also need an alignment after the lift, and towing owners should read tyre rules for towing. Sibling guides worth a look if you are cross-shopping tourers: the Toyota HiLux, Ford Ranger and Ford Everest guides.
Bottom line: The LC300’s tyre size follows its grade — 245/75R17, 265/65R18 or 265/55R20 — on a shared 6×139.7 wheel with a 95.1 mm bore and a full-size spare on every model. It is a heavy tow vehicle, so never drop below the placard load rating, set cold pressures from the door placard, and buy five tyres so the spare matches. Confirm every figure against your own vehicle before you buy.
Frequently asked questions
What size tyres are on a LandCruiser 300 GX?
As a 2026 guide the GX runs 245/75R17 on 17-inch steel wheels — the tallest-sidewall, most touring-friendly fitment in the range. Confirm against your placard.
What is the bolt pattern on a LandCruiser 300?
6×139.7 mm with a 95.1 mm centre bore and roughly +60 mm factory offset. It shares the pattern with the HiLux and Prado, but offset and bore still have to match for a clean fit.
Does the LandCruiser 300 come with a full-size spare?
Yes — every grade carries a full-size under-slung spare, one of the LC300’s real advantages for remote travel. Keep it inflated and exercise the winch cradle.
What pressure should LandCruiser 300 tyres be?
Follow the cold pressures on your driver’s door placard, which differ by grade and rise for loaded and towing use. Do not use the sidewall maximum as your everyday pressure.
Can I fit 33-inch tyres to a LandCruiser 300?
Many owners fit around 285/70R17 (~33 inches), but you must keep the placard load rating, manage speedo error and clearance, and stay inside your state’s rolling-diameter limits. A lift and engineering may be required — confirm first.
This guide is general information for Australian drivers and uses 2026 figures that change over time. Tyre sizes, pressures, load ratings and prices must be confirmed against your vehicle’s placard, owner’s manual and a licensed tyre retailer or your state road authority.
