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.

Lexus IS 300 OE Wheel Specs

The 2001-2004 Lexus IS 300 (Sedan) uses a 5x114.3 bolt pattern with a 60.1mm center bore. Factory wheels are 17x7.0J 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

Flush Fitment

For a flush look, F/R 17x8.0J ET35 is a commonly used starting point — clearance must be verified on a stock or mildly lowered Lexus IS 300.

Maximum Aggressive Fitment

F/R 17x9.0J ET26 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Real-World Reference Cases

The examples below are compiled from typical ANKUSI customer configurations and are labeled as reference cases, not individually verified real-world builds.

Case 1: Daily Driver (Factory-Style)

Profile: Everyday driving, prioritizes comfort and low running cost.

Setup: 17x7.0J ET50

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: 17x8.0J ET35

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: 17x9.0J ET26

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 Lexus IS 300 owners.

Offset & Backspacing Reference

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

OE: 17x7.0J ET50 → ~5.97″ backspacing
Flush: 17x8.0J ET35 → ~5.88″ backspacing
Max: 17x9.0J ET26 → ~6.02″ 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 Lexus spec, or want a wheel built to a custom offset for your Lexus IS 300? 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 Lexus IS 300 use?

The 2001-2004 Lexus IS 300 uses a 5x114.3 bolt pattern.

How many lug bolts does the Lexus IS 300 use?

The Lexus IS 300 uses a 5-lug bolt pattern (5x114.3), so you need a 5-lug forged wheel to bolt straight on.

What is the center bore size on the Lexus IS 300?

The Lexus IS 300's center bore is 60.1mm. 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 Lexus IS 300?

Factory wheels on the Lexus IS 300 are 17x7.0J F/R.

What is the biggest wheel size I can fit on my Lexus IS 300 without rubbing?

The most aggressive fitment we recommend without fender work is 17x9.0J at ET26 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 Lexus IS 300?

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 Lexus IS 300.

Do I need wheel spacers for my Lexus IS 300?

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 Lexus IS 300?

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 Lexus IS 300?

The Lexus IS 300 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.
