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

A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.

The Chrysler 300C SRT8 runs a 5x115 bolt pattern, 71.5mm center bore, and a 20x9.0J, front and rear, wheel from the factory. Our Flush Fitment reference is 20x10.0J ET18, which tucks the tire under the fender lip on a stock-height Chrysler 300C SRT8. Our Maximum Aggressive reference is 20x10.5J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.

Chrysler 300C SRT8 OE Wheel Specs

The 2005 Chrysler 300C SRT8 (Sedan) uses a 5x115 bolt pattern with a 71.5mm center bore. Factory wheels are 20x9.0J F/R.

Why the factory spec works for most owners:

Balances ride comfort with everyday fuel efficiency
A widely used size in this segment, so tire and wheel availability stays strong
Keeps unsprung weight low for stable, predictable handling
Maintains clearance for the factory brake calipers and suspension components

ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Chrysler 300C SRT8 (2005) we drill the 5x115 pattern and cut the centre bore to 71.5mm 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 with minimal rubbing, F/R 20x10.0J ET18 is the recommended starting point on a stock or mildly lowered Chrysler 300C SRT8.

Maximum Aggressive Fitment

F/R 20x10.5J ET15 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Cost: ~$620

Outcome: Minimal visual change, ride and fuel economy essentially unaffected.

Case 2: Balanced Enthusiast (Balanced / Flush Fit)

Profile: Wants a sportier stance without sacrificing daily usability.

Setup: 20x10.0J ET18

Cost: ~$3,000

Outcome: Noticeable visual upgrade, fuel economy drop within the expected range.

Case 3: Show Build (Max Aggressive)

Profile: Built primarily for shows or occasional track/show use.

Setup: 20x10.5J ET15

Cost: ~$5,500

Outcome: Maximum visual impact; daily comfort and fuel economy are heavily compromised, physical test fit required before production.

Decision Guide

What's your primary use? Daily commuting → Tier A/B. Weekend street driving → Tier B/C. Show or occasional track use → Tier D/E.

What's your budget? Under $800 → Tier A. $800-3,400 → Tier B/C. $3,400+ → Tier D/E.

How much does fuel economy matter? Very important → Tier A. Somewhat important → Tier B/C. Not a priority → Tier D/E.

Still unsure? Tier C (Balanced / Flush Fit) is the default choice for most Chrysler 300C SRT8 owners.

Offset & Backspacing Reference

Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):

OE: 20x9.0J ET24 → ~5.94″ backspacing
Flush: 20x10.0J ET18 → ~6.21″ backspacing
Max: 20x10.5J ET15 → ~6.34″ backspacing

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 Chrysler spec, or want a wheel built to a custom offset for your Chrysler 300C SRT8? 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 Chrysler 300C SRT8 (2005)

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 5x115 pattern and the 71.5mm 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 Chrysler orders on this platform land somewhere between the 20x10.0J ET18 flush setup and the 20x10.5J ET15 aggressive setup referenced above.

Designs we already tool for the 5x115 pattern — each one is re-cut to your sizes and offsets:

Frequently Asked Questions

What bolt pattern (PCD) does the Chrysler 300C SRT8 use?

The 2005 Chrysler 300C SRT8 uses a 5x115 bolt pattern.

How many lug bolts does the Chrysler 300C SRT8 use?

The Chrysler 300C SRT8 uses a 5-lug bolt pattern (5x115), so you need a 5-lug forged wheel to bolt straight on.

What is the center bore size on the Chrysler 300C SRT8?

The Chrysler 300C SRT8's center bore is 71.5mm. 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 Chrysler 300C SRT8?

Factory wheels on the Chrysler 300C SRT8 are 20x9.0J F/R.

What is the biggest wheel size I can fit on my Chrysler 300C SRT8 without rubbing?

The most aggressive fitment we recommend without fender work is 20x10.5J 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 Chrysler 300C SRT8?

For a flush look with minimal to no rubbing, we recommend 20x10.0J at ET18 offset as a starting point on a stock or mildly lowered Chrysler 300C SRT8.

Do I need wheel spacers for my Chrysler 300C SRT8?

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 Chrysler 300C SRT8?

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 6.21" 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 Chrysler 300C SRT8?

The Chrysler 300C SRT8 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.
