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
The Toyota 4Runner 40th Anniversary's factory suspension tuning already accounts for a specific unsprung mass target. Forged construction lets ANKUSI match the factory strength spec while keeping rotational weight down, which is where the real handling benefit comes from on a taller, heavier SUV platform.
The Toyota 4Runner 40th Anniversary runs a 6x139.7 bolt pattern, 106.1mm center bore, and a 17x7.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x8.5J ET0, which tucks the tire under the fender lip on a stock-height Toyota 4Runner 40th Anniversary. Our Maximum Aggressive reference is 18x9.0J ET-5 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Toyota 4Runner 40th Anniversary OE Wheel Specs
The 2023 Toyota 4Runner 40th Anniversary (SUV) uses a 6x139.7 bolt pattern with a 106.1mm center bore. Factory wheels are F/R: 17x7.5J 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
Flush Fitment
For a flush look, F/R 17x8.5J ET0 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Toyota 4Runner 40th Anniversary.
Maximum Aggressive Fitment
F/R 18x9.0J ET-5 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F/R: 17x7.5J ET15 → ~4.84″ backspacing
- Flush: 17x8.5J ET0 → ~4.75″ backspacing
- Max: 18x9.0J ET-5 → ~4.8″ 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 40th Anniversary? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

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.
