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 Dodge Ram 1500 runs a 5x139.7 bolt pattern, 77.8mm center bore, and a 17x7.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x9.0J ET20, which tucks the tire under the fender lip on a stock-height Dodge Ram 1500. Our Maximum Aggressive reference is 20x10.0J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Dodge Ram 1500 OE Wheel Specs
The 2009 Dodge Ram 1500 (Pickup) uses a 5x139.7 bolt pattern with a 77.8mm center bore. Factory wheels are 17x7.0J 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 Dodge Ram 1500 (2009) we drill the 5x139.7 pattern and cut the centre bore to 77.8mm 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: 17x7.0J ET19.05 → ~4.75″ backspacing
- Flush: 20x9.0J ET20 → ~5.79″ backspacing
- Max: 20x10.0J ET15 → ~6.09″ 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 Dodge spec, or want a wheel built to a custom offset for your Dodge Ram 1500? 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 Dodge Ram 1500 use?
The 2009 Dodge Ram 1500 uses a 5x139.7 bolt pattern.
How many lug bolts does the Dodge Ram 1500 use?
The Dodge Ram 1500 uses a 5-lug bolt pattern (5x139.7), so you need a 5-lug forged wheel to bolt straight on.
What is the center bore size on the Dodge Ram 1500?
The Dodge Ram 1500's center bore is 77.8mm. 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 Dodge Ram 1500?
Factory wheels on the Dodge Ram 1500 are 17x7.0J F/R.
What is the biggest wheel size I can fit on my Dodge Ram 1500 without rubbing?
The most aggressive fitment we recommend without fender work is 20x10.0J at ET15 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 Dodge Ram 1500?
For a flush look with minimal to no rubbing, we recommend 20x9.0J at ET20 offset as a starting point on a stock or mildly lowered Dodge Ram 1500.
Do I need wheel spacers for my Dodge Ram 1500?
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 Dodge Ram 1500?
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 5.79" 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 Dodge Ram 1500?
The Dodge Ram 1500 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.
