What is the 79 Series GXL Factory Rim Size?
Knowing the factory rim spec on the 79 Series GXL is essential before any wheel upgrade. The dimensions affect speedometer accuracy, brake clearance, fender flare requirements and ADR compliance. The good news is that the factory spec has been consistent across the current production run, so any 79 GXL rim spec discussion applies to vehicles from 1999 through to the current 2024 facelift.
This guide covers the factory wheel dimensions, what they mean for aftermarket fitment, and the most common upgrade sizes.
1. Factory Rim Dimensions
The 79 Series GXL factory rim is 16 x 7 inches (16-inch diameter, 7-inch width). Offset is approximately ET+5 mm (positive 5 mm) - the mounting face sits 5 mm outboard of the rim centreline. Hub bore is 110.3 mm. Wheel studs are M14 x 1.5 thread with 21 mm hex factory wheel nuts.
Stud pattern is 5x150 (five studs on a 150 mm pitch circle diameter), the same as the 100 Series and 200 Series LandCruisers. This is the heavy-duty Toyota 4WD pattern - separate from the 5x150 used on Hilux and Prado.
2. Factory Tyre Size
The factory tyre on the 79 GXL is 265/70R16 - 31.6 inches overall diameter, 265 mm section width. Construction is typically a light-truck highway-terrain such as Bridgestone Dueler or Dunlop Grandtrek depending on production year.
3. Differences Across Production Years
Wheel and tyre dimensions have not changed across the HZJ79 (pre-V8), VDJ79 (V8 era 2007 to late 2024) and the GDJ79 (2.8L facelift, late 2024 onward). The 2024 facelift retained the 16-inch wheel size, the 5x150 stud pattern, the same offset and hub bore. Steel and alloy versions are interchangeable - same backspacing, same hub bore.
4. Aftermarket Wheel Fitment Guidelines
Aftermarket 16-inch or 17-inch wheels with 5x150 stud pattern, 110.3 mm hub bore (or hub-centric ring) and offset close to ET+5 will fit. Offset variations of ±15 mm from factory are common in aftermarket wheels; wider offsets (less positive or negative) push the wheel outward and may require fender flares for ADR compliance. Hub-centric rings (plastic or alloy spacers that fill the gap between a larger aftermarket hub bore and the 110.3 mm 79 Series hub) are recommended where the wheel hub bore is bigger than 110.3 mm.
5. Common Aftermarket Sizes
17 x 8-inch with 5x150 stud pattern is the popular touring upgrade - keeps the factory tyre diameter at 265/65R17 (31.5 inches) or moves up to 285/70R17 (32.7 inches) on a wider rim. 17 x 9-inch with -10 offset accommodates 33-inch tyres but requires fender flares. 16-inch steel sunraysia-style aftermarket wheels remain popular for working and rural use because they match factory geometry and are cheap to replace if damaged.
