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
Trucks live and die on unsprung weight and load capacity — every pound added at the wheel is a pound the suspension has to control over every bump, fully loaded or not. Forging the wheel instead of casting it lets us hold the factory load rating while cutting rotational mass, which pays off directly in ride quality and steering response on a vehicle that spends real time towing or hauling.
The Toyota Tacoma TRD Pro Series runs a 6x139.7 bolt pattern, 106.1mm center bore, and a 16x7.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 17x8.0J ET35, which tucks the tire under the fender lip on a stock-height Toyota Tacoma TRD Pro Series. Our Maximum Aggressive reference is 18x8.5J ET30 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Toyota Tacoma TRD Pro Series OE Wheel Specs
The 2015 Toyota Tacoma TRD Pro Series (Off-Road Pickup) uses a 6x139.7 bolt pattern with a 106.1mm center bore. Factory wheels are F/R: 16x7.0J F/R.
Why the factory spec works for most owners:
- Supports higher payload and towing capacity
- Preserves ground clearance for towing, hauling and light off-road use
- Matches tire sizing commonly available for this class of vehicle
- Maintains clearance for the factory suspension and brake package
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Toyota Tacoma TRD Pro Series (2015) we drill the 6x139.7 pattern and cut the centre bore to 106.1mm 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.
Converting these ET figures to backspacing? Use the wheel offset and backspacing calculator.
The figures on this page are part of our open wheel fitment dataset — 10,093 vehicles, free to download, CC BY 4.0.
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F/R: 16x7.0J ET30 → ~5.18″ backspacing
- Flush: 17x8.0J ET35 → ~5.88″ backspacing
- Max: 18x8.5J ET30 → ~5.93″ 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 Tacoma TRD Pro Series? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Frequently Asked Questions
What bolt pattern (PCD) does the Toyota Tacoma TRD Pro Series use?
The 2015 Toyota Tacoma TRD Pro Series uses a 6x139.7 bolt pattern.
How many lug bolts does the Toyota Tacoma TRD Pro Series use?
The Toyota Tacoma TRD Pro Series 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 Tacoma TRD Pro Series?
The Toyota Tacoma TRD Pro Series's center bore is 106.1mm. 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 Tacoma TRD Pro Series?
Factory wheels on the Toyota Tacoma TRD Pro Series are F/R: 16x7.0J F/R.
What is the biggest wheel size I can fit on my Toyota Tacoma TRD Pro Series without rubbing?
The most aggressive fitment we recommend without fender work is 18x8.5J at ET30 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 Tacoma TRD Pro Series?
For a flush look with minimal to no rubbing, we recommend 17x8.0J at ET35 offset as a starting point on a stock or mildly lowered Toyota Tacoma TRD Pro Series.
Do I need wheel spacers for my Toyota Tacoma TRD Pro Series?
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 Tacoma TRD Pro Series?
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 5.88" 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 Tacoma TRD Pro Series?
The Toyota Tacoma TRD Pro Series 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.
