Quick answer
The Hilux Surf KZN130 and KZN185 (and the 90-Series Prado, the 1996–2002 4Runner) all share the same wheel fitment specs:
- Stud pattern (PCD): 6 × 139.7 mm (also written as 6 × 5.5")
- Centre bore: 106.1 mm
- Stud thread: M12 × 1.5
- Factory wheel size: 15 × 7" (KZN130 and base KZN185), 16 × 7" (later/higher-spec KZN185)
- Factory offset (ET): +25 to +30 mm
- Wheel torque: 110 Nm
Tyre sizes that fit: 30" (265/75R15) is the stock-spec sweet spot. 31" fits with a 2" lift and mild guard work. 32" needs a 2"+ lift and trimming. 33" is build territory. 35" ("hilux surf 35s") requires significant lift, body work, and re-gearing, possible but not bolt-on.
Stud pattern and PCD
The 6 × 139.7 mm pattern is one of Toyota's standard 4WD bolt patterns. Vehicles that share it:
- All Hilux Surfs (1st through 5th gen)
- 1996–2002 Toyota 4Runner
- 90-Series Land Cruiser Prado (KZJ95 / KDJ95 / VZJ95)
- 100-Series Land Cruiser (some variants)
- 80-Series Land Cruiser (some)
- Toyota Hilux pickups of the same era
- FJ Cruiser
- Tacoma (some)
This is great news for wheel shopping, anything tagged for any of those vehicles will bolt up. Always verify offset and centre bore separately, same stud pattern doesn't guarantee good fitment.
Centre bore and hubcentric vs lugcentric
The Surf hub is 106.1 mm centre bore. Wheels that match this exactly are "hubcentric", they centre on the hub, not on the studs.
If you buy aftermarket wheels with a larger centre bore (say 110 mm or 113 mm), you need hubcentric rings to fill the gap. Without them, the wheels rely on the studs alone for centring, which causes vibration at speed and accelerates stud wear.
Standard Toyota 6-stud aftermarket wheels are usually hubcentric to the 106.1 bore. Universal multi-fit wheels often need rings.
Offset (ET): what to know
Stock Surf offset is around +25 to +30 mm, meaning the wheel mounting face is 25–30 mm outboard of the wheel centreline.
Lower offset = wheel pokes out further (more aggressive look, more strain on bearings, can rub guards)
Higher offset = wheel tucks in deeper (more conservative look, can rub strut/coilover, factory factor)
Common aftermarket Surf builds run +10 to +20 mm offset for a slightly poked stance with bigger tyres. Going much lower than +10 starts overloading the wheel bearings and causing handling issues.
If you're running a bull bar with mounted lights, you may want to keep closer to factory offset for clearance.
Tyre size, what fits realistically
Stock setup (LT265/75R15 or 31x10.50R15): - Fits with no modification - 30" overall diameter - Best ride quality, best fuel economy, lowest noise
31" tyres (e.g., 265/75R16, 31x10.50R15): - Fits stock with minor rubbing on full-lock turns - 2" lift eliminates the rub - Slight gearing change, slight economy hit
32" tyres (e.g., 285/75R16, 32x11.50R15): - Needs a 2" lift minimum - Mild guard trimming on full lock and full droop - Noticeable gearing change, first/second gear feel taller, may need to re-gear or accept it
33" tyres (e.g., 285/75R16 oversize, 33x12.50R15): - Needs 2.5"–3" of lift - Real guard / wheel arch trimming required - Should re-gear (4.56 or 4.88 diff ratios) to recover lost off-road crawl
35" tyres ("hilux surf 35s"): - 4"+ lift required, plus body lift, plus serious wheel arch surgery - Should re-gear to 4.88 or 5.29 - Brake performance becomes a real consideration - This is build territory, not bolt-on
Common wheel options that fit
Direct fitment options most owners look at:
- Factory 16" alloys from a higher-spec KZN185 or 90-Series Prado, clean, OE look
- Method Race Wheels, popular with the overland crowd
- King Off-Road / KMC, wide range of styles
- JDM steel wheels ("hilux surf alloys" search territory), period-correct look for restoration builds
Plus-sizing to 17" or 18" works on a Surf but loses sidewall and ride compliance, most off-road owners stay with 15" or 16".
Five things to check before you buy wheels and tyres
- PCD verification, yes the Surf is 6×139.7, but confirm the wheel listing matches exactly. Some "6×139.7" wheels are actually 6×135 or 6×127 in disguise.
- Hubcentric or lugcentric?, get rings if needed.
- Offset within ±15 mm of factory for daily use, ±20 mm for build use.
- Load rating on tyres, minimum load index 113 for a Surf (matches stock). Going below this is unsafe especially with a heavy build.
- Tyre speed rating, Q (160 km/h) is the minimum for a passenger Surf. R or S adds margin.
Where to source parts
The 3rd Gen collection and 2nd Gen collection are the catalogue starting points for fitment-specific parts. Wheels and tyres themselves we don't typically stock, we recommend a local 4WD wheel and tyre specialist for these.

FAQ
What's the wheel stud pattern (PCD) on a Hilux Surf? 6 × 139.7 mm (6 × 5.5"). Same as the 90-Series Prado, 1996–2002 4Runner, and many other Toyota 6-stud 4WDs.
What's the centre bore of a Hilux Surf wheel hub? 106.1 mm. Use hubcentric rings if your aftermarket wheels have a larger centre bore.
Will 90-Series Prado wheels fit my Hilux Surf? Yes, same stud pattern, same centre bore, similar offsets.
What's the biggest tyre I can fit on a stock Hilux Surf? 31" with mild guard rubbing on full lock. 32" needs a 2" lift. 33"+ needs serious modifications.
Can you fit 35" tyres on a Hilux Surf? Yes, but it's a build, not a bolt-on. You'll need 4"+ lift, body lift, wheel arch surgery, and ideally re-gearing.
What's the wheel torque spec for a Hilux Surf? 110 Nm (about 81 lb-ft) on M12×1.5 studs.
