The Toyota Land Cruiser 20 Series (J20), produced between 1955–1960, represents one of the earliest civilian-oriented Land Cruiser models. Built on a rugged ladder chassis with leaf suspension, it was designed primarily for durability and off-road use rather than modern comfort.

Due to its age, factory specifications are less standardized compared to modern vehicles, but based on historical data and cross-referencing with Land Cruiser fitment databases, we can establish accurate working specifications for tyre, wheel, and hub data.
Factory Wheel & Tyre Specifications
OEM Tyre Sizes (Period-Correct)
- 6.00-16 (factory standard cross-ply)
- 6.50-16 (optional upgrade)
- 7.00-16 (heavy-duty / off-road use)
Modern Equivalent Tyre Sizes
For customers running restored or modified vehicles:
- 215/85R16
- 235/85R16
- 245/75R16
These maintain similar rolling diameter while improving drivability and availability.
Factory Rim Specifications
- Rim Size: 16x4.5 – 16x5.5
- Wheel Type: Steel (multi-piece / split rim common)
- Offset: Approx. 0 to -10 mm
- Stud Pattern (PCD): 6x139.7 mm
The 6x139.7 PCD remains consistent across most Land Cruiser generations, making wheel upgrades easier.
Centre Bore (CB)
- Centre Bore: ~110 mm (hub-centric design varies due to early production tolerances)
Important note:
Early Land Cruisers are typically lug-centric, meaning centre bore is less critical than modern vehicles. However, correct hub fitment is still recommended for safety and load distribution.
Wheel Nut / Stud Specifications
- Thread Size: M12 x 1.5
- Seat Type: Conical (varies depending on aftermarket wheels)
Torque Specifications
- Wheel Nut Torque:
90–110 Nm
Because of the age of these vehicles, always:
- Re-torque after 50–100 km
- Inspect studs regularly (common wear point on vintage 4WDs)
Fitment Notes & Upgrade Guide
Common Upgrades
Owners typically upgrade to:
- 16x7 or 16x8 wheels
- All-Terrain tyres such as 235/85R16
Aggressive Off-Road Setup
- 285/75R16 (requires lift and clearance mods)
- Negative offset wheels for wider stance
Key Considerations
- Brake clearance (especially upgraded disc conversions)
- Steering lock clearance
- Guard trimming for larger tyres
A neutral offset (~ET0) is widely recommended for Land Cruiser platforms to balance clearance and stability.
Recommended Tyre Options (Australia Use)
For classic Land Cruiser builds in Australia:
- All Terrain (AT): Best balance for road + off-road
- Mud Terrain (MT): For heavy off-road builds
- Highway Terrain (HT): For restored / show vehicles
