How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
SUVs carry more curb weight higher off the ground, so wheel strength and rotational mass both matter more than on a comparable sedan — a heavier wheel amplifies body roll and slows steering response exactly where the platform is already working hardest. Forging keeps the wheel light without giving up the load rating the factory suspension geometry was tuned around.
The Toyota 4Runner Trailhunter runs a 6x139.7 bolt pattern, 95.1mm center bore, and a 18x7.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 18x8.5J ET25, which tucks the tire under the fender lip on a stock-height Toyota 4Runner Trailhunter. Our Maximum Aggressive reference is 20x9.0J ET20 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Toyota 4Runner Trailhunter OE Wheel Specs
The 2025 Toyota 4Runner Trailhunter (Rugged SUV) uses a 6x139.7 bolt pattern with a 95.1mm center bore. Factory wheels are F/R: 18x7.5J F/R.
Why the factory spec works for most owners:
- Supports the vehicle's curb weight and load capacity
- Preserves ground clearance for everyday and light off-road use
- Balances ride comfort with cargo and passenger stability
- Maintains clearance for the factory suspension travel and brake package
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Toyota 4Runner Trailhunter (2025) we drill the 6x139.7 pattern and cut the centre bore to 95.1mm on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Flush Fitment
For a flush look, F/R 18x8.5J ET25 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Toyota 4Runner Trailhunter.
Maximum Aggressive Fitment
F/R 20x9.0J ET20 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
1
What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.
2
What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.
3
How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.
4
Still unsure? Tier C (Balanced) is the default choice for most Toyota 4Runner Trailhunter owners.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F/R: 18x7.5J ET35 → ~5.63″ backspacing
- Flush: 18x8.5J ET25 → ~5.73″ backspacing
- Max: 20x9.0J ET20 → ~5.79″ backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Toyota spec, or want a wheel built to a custom offset for your Toyota 4Runner Trailhunter? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Toyota 4Runner Trailhunter (2025)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 6x139.7 pattern and the 95.1mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose — most Toyota orders on this platform land somewhere between the 18x8.5J ET25 flush setup and the 20x9.0J ET20 aggressive setup referenced above.

Toyota Tacoma Off-Road 6-Lug Forged Wheels – Matte Black Semi-Full-FaceFrequently Asked Questions
What bolt pattern (PCD) does the Toyota 4Runner Trailhunter use?
The 2025 Toyota 4Runner Trailhunter uses a 6x139.7 bolt pattern.
How many lug bolts does the Toyota 4Runner Trailhunter use?
The Toyota 4Runner Trailhunter uses a 6-lug bolt pattern (6x139.7), so you need a 6-lug forged wheel to bolt straight on.
What is the center bore size on the Toyota 4Runner Trailhunter?
The Toyota 4Runner Trailhunter's center bore is 95.1mm. If an aftermarket wheel has a larger center bore than this, hub-centric rings are recommended so the wheel centers on the hub itself rather than relying on the lug bolts alone.
What size are the factory (stock) wheels on the Toyota 4Runner Trailhunter?
Factory wheels on the Toyota 4Runner Trailhunter are F/R: 18x7.5J F/R.
What is the biggest wheel size I can fit on my Toyota 4Runner Trailhunter without rubbing?
The most aggressive fitment we recommend without fender work is 20x9.0J at ET20 offset. Going beyond this typically causes rubbing under compression unless you roll the fenders or add camber correction.
What does a flush wheel fitment look like on the Toyota 4Runner Trailhunter?
For a flush look with minimal to no rubbing, we recommend 18x8.5J at ET25 offset as a starting point on a stock or mildly lowered Toyota 4Runner Trailhunter.
Do I need wheel spacers for my Toyota 4Runner Trailhunter?
No. ANKUSI forges each wheel to your exact target offset, including the flush or max specs above, so you get the correct fitment without stacking spacers. Spacers are typically only used to push out an existing OE-offset wheel without replacing it, which isn't necessary when you're ordering a custom-offset forged wheel.
How do I calculate wheel backspacing for my Toyota 4Runner Trailhunter?
Backspacing (in inches) = wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance). For example, the flush spec above works out to roughly 5.73" of backspacing.
What's the difference between wheel offset and backspacing?
Offset is the distance in millimeters from the wheel's true centerline to its mounting face (positive offset pulls the wheel in, negative pushes it out). Backspacing is the distance in inches from the mounting face to the back edge of the wheel barrel. They describe the same fitment from two different reference points, which is why ANKUSI lists both above — some shops and tuning guides quote offset, others quote backspacing.
Can I run staggered wheels (different sizes front and rear) on my Toyota 4Runner Trailhunter?
The Toyota 4Runner Trailhunter runs the same wheel size front and rear from the factory, so staggered fitment is not required. ANKUSI can still forge a staggered set (wider rear) on request if you want a more aggressive stance.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.5, conical-seat lug nut.
Factory Torque Spec: 103-110 Nm (76-81 ft-lb). Range covers most Toyota passenger cars, crossovers, and light trucks on M12x1.5 studs.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
