Collection: Infiniti G37 Replacement Rims

The Infiniti G37 is the sport-luxury coupe, sedan, and convertible that carried Infiniti's compact performance line from 2008 through 2013, before the nameplate gave way to the Q50 and Q60. Factory wheel sizes on the G37 vary more by body style and trim than by any true generation change, since the car ran on a single V36 platform for its entire production run while wheel width, offset, and tire size shifted noticeably between the base Sedan, the Coupe, and the performance-oriented Sport and IPL configurations. Because of that spread, body style and trim matter as much as bolt pattern when identifying the correct OEM wheel for a given G37. This guide covers the documented bolt pattern, center bore, and complete rim dimensions across the G37's production run, along with how the factory wheel lineup changed by body style and trim.

Quick Specs at a Glance

What Size Wheels Does the Infiniti G37 Have?

It depends on body style and trim. The base G37 Sedan runs a 17-inch wheel with a 225/55R17 tire, confirmed in factory tire-size documentation for the 2009 through 2013 model years, though the exact wheel width was not verified in the available source material. Sedan Journey and Sport trims step up to an 18-inch staggered setup, with a 18x7.5 wheel and 225/50R18 tire up front and an 18x8.5 wheel and 245/45R18 tire in the rear, both figures confirmed for the G37 Sport and G37x Sport Sedan.

The G37 Coupe's non-Sport configuration uses an 18-inch wheel with a square 225/50R18 tire front and rear. The Convertible's non-Sport configuration also uses an 18-inch wheel, but with staggered tire sizing of 225/50R18 front and 245/45R18 rear. Both of those tire sizes are confirmed in factory tire-size documentation, though the wheel width was not verified for either non-Sport configuration. Coupe and Convertible models equipped with the Sport Package, along with the Coupe Sport and Convertible Sport and Anniversary Edition trims, move to a staggered 19-inch setup: a 19x8.5 wheel and 225/45R19 tire up front, and a 19x9 wheel and 245/40R19 tire in the rear. Those dimensions are confirmed specifically for the Coupe's 19-inch 10-spoke Sport wheel.

The IPL Coupe, Infiniti's performance-oriented G37 variant, used a 19-inch staggered factory wheel that owner and parts documentation describes as sharing the same front dimension as the Sport Package wheel, a 19x8.5 front. Rear width and tire sizing for the IPL wheel are reported inconsistently across available sources, with some documentation showing a 19x9 rear matching the Sport Package and others showing a wider 19x9.5 rear with different tire sizing, so those specific rear figures are not treated as fully confirmed here.

What Is the Bolt Pattern on the Infiniti G37?

The documented G37 Sedan, Coupe, and Convertible configurations use a 5x114.3 bolt pattern throughout the 2008 through 2013 model-year range. A consistent bolt pattern across the lineup does not by itself mean every G37 wheel is a direct fit for every other G37, since wheel width, offset, and tire size still vary considerably by body style and trim, and the staggered Sport and IPL setups in particular are not interchangeable with the non-staggered wheels used on base trims.

Infiniti G37 Center Bore and Offset

Center bore is documented at 66.1mm across the G37's full production run, consistent across Sedan, Coupe, and Convertible body styles. Offset is confirmed at ET45 on the Sedan Sport's 18x7.5 front wheel and ET50 on its 18x8.5 rear wheel. On the Coupe's 19-inch Sport wheel, offset is confirmed at ET43 up front and ET45 in the rear. Offset was not verified for the base 17-inch Sedan wheel or for the non-Sport 18-inch Coupe and Convertible wheel, so those figures are left out here rather than estimated.

Do Infiniti G37 Wheels Interchange Between Model Years?

G37 factory wheels can vary by body style, model year, trim, and configuration. A shared bolt pattern and center bore alone do not establish complete direct-fit interchangeability. The 5x114.3 bolt pattern and 66.1mm center bore remain consistent across every documented G37 body style and model year, but wheel width, offset, tire size, and front-to-rear configuration still vary considerably. The staggered 18-inch Sedan Sport setup and the staggered 19-inch Coupe and Convertible Sport setup have different dimensions and intended tire sizing from the non-staggered base wheels, so each factory wheel specification should be considered individually rather than assumed to interchange across trims or body styles.

About the Infiniti G37

The Infiniti G37 is a sport-luxury car built for buyers cross-shopping the BMW 3 Series and Lexus IS who wanted a distinct, rear-wheel-drive-based alternative with available all-wheel drive. It replaced the G35 for the 2008 model year, arriving first as a coupe before the sedan and a retractable-hardtop convertible joined the lineup for 2009.

The G37 was built on the V36 platform throughout its production run, powered by a 3.7-liter VQ37VHR V6 making between roughly 325 and 330 horsepower depending on model year and trim. All-wheel drive, badged G37x, became available across all three body styles by the 2010 model year. Performance-oriented IPL versions arrived for the G37 Coupe in 2011 and the Convertible in 2013, adding a more performance-focused factory wheel and suspension package. Infiniti retired the G37 name after the 2013 model year, with the sedan becoming the Q50 and the coupe and convertible becoming the Q60 as part of the brand's shift to Q-based naming.

The factory wheel lineup reflects that body-style and trim spread more than any single redesign. The documented base Sedan configuration uses a 17-inch wheel, the documented Sedan Sport configuration uses a staggered 18-inch setup, and the documented Coupe and Convertible Sport configurations use a staggered 19-inch setup. The IPL Coupe introduced a more performance-focused staggered factory wheel package, although its exact rear wheel dimension is inconsistently reported in the available documentation.

G37 Sedan vs. Coupe vs. Convertible Wheels

Wheel sizing differs by body style mainly at the entry level. The Sedan's base wheel is a 17-inch design not offered on the Coupe or Convertible, both of which start at 18 inches. Even at that shared 18-inch non-Sport level, the two body styles are not identical: the Coupe runs a square 225/50R18 tire, while the Convertible runs staggered 225/50R18 front and 245/45R18 rear tires. Once a G37 is optioned with the Sport Package or a Sport trim, the Sedan and the Coupe/Convertible diverge again: the Sedan Sport setup stays at 18 inches (staggered 18x7.5 front, 18x8.5 rear), while the Coupe and Convertible Sport setup steps up to a staggered 19-inch wheel (19x8.5 front, 19x9 rear). Because these details vary by body style, trim, and even non-Sport configuration, body style and trim should both be confirmed together rather than assumed from one or the other.

OEM Wheel Sizes & Fitment by Trim (V36, 2008-2013)

Why Choose Genuine OEM Wheels?

• Factory fit and specifications. Genuine OEM wheels are designed around the G37's factory bolt pattern, offset, and hub bore for the specific body style and trim.
• Correct staggered configuration. OEM wheels preserve the correct front-to-rear width and offset relationship on Sport and IPL models, rather than approximating a staggered look.
• Original styling and factory appearance. A stock-style wheel keeps the G37 looking factory-correct, which matters if you plan to sell later.

OEM vs. Replica & Aftermarket Wheels

How the G37 Compares

Shoppers cross-shopping the G37 typically also look at the BMW 3 Series and the Lexus IS, both established competitors in the sport-luxury segment. The G37 has its own model-specific bolt pattern, center bore, and offset specifications, so competitor wheels should not be assumed to be direct-fit replacements.

Frequently Asked Questions

What size wheels does the Infiniti G37 have?
It depends on body style and trim. The base Sedan uses a 17-inch wheel, non-Sport Coupe and Convertible models use an 18-inch wheel, the Sedan Sport uses a staggered 18-inch setup (18x7.5 front, 18x8.5 rear), and the Coupe and Convertible Sport trims use a staggered 19-inch setup (19x8.5 front, 19x9 rear).

What is the bolt pattern on the Infiniti G37?
The documented G37 Sedan, Coupe, and Convertible configurations use a 5x114.3 bolt pattern throughout the 2008 through 2013 model-year range.

What is the center bore of the Infiniti G37?
The G37 uses a 66.1mm center bore across its entire production run and all three body styles.

What offset do Infiniti G37 wheels use?
Offset is confirmed at ET45 front and ET50 rear on the Sedan Sport's staggered 18-inch wheel, and ET43 front and ET45 rear on the Coupe Sport's staggered 19-inch wheel. Offset was not verified for the base 17-inch Sedan wheel or the non-Sport 18-inch Coupe and Convertible wheel.

Do Infiniti G37 wheels interchange between model years?
The 5x114.3 bolt pattern and 66.1mm center bore remain consistent across every documented G37 body style and model year, but that does not establish complete wheel interchangeability. Wheel width, offset, tire size, body style, and trim still vary, so each factory wheel specification should be considered individually.

Do G37 Sedan and Coupe wheels differ?
Yes. The Sedan's base wheel is a 17-inch design not offered on the Coupe, and the Sedan Sport setup stays at 18 inches while the Coupe Sport setup steps up to a staggered 19-inch wheel with different offsets.

What is the largest factory wheel size on the Infiniti G37?
The largest fully documented factory rim dimension in the available source material is the Coupe and Convertible Sport's 19x9 rear wheel, paired with a 19x8.5 front wheel. Some IPL documentation reports a 19x9.5 rear wheel, but that dimension is not consistently confirmed.

Are OEM Infiniti G37 wheels better than replicas?
A genuine OEM wheel is designed around the G37's factory fitment for its specific body style and trim, including the correct staggered front-to-rear relationship on Sport and IPL setups, while keeping the car's original appearance.

Final Thoughts

The Infiniti G37's wheel fitment stays consistent at the hub level across its entire 2008 through 2013 run: a 5x114.3 bolt pattern and a 66.1mm center bore apply to every body style and trim. What changes is wheel width, offset, and tire size, from the base Sedan's 17-inch wheel through the staggered 18-inch Sedan Sport setup and the staggered 19-inch Coupe and Convertible Sport setup. The IPL Coupe adds a more performance-focused factory wheel package, though its exact rear dimension is reported inconsistently across available documentation. Genuine OEM wheels remain the simplest way to get factory-correct fit and styling for your specific G37, whether replacing a curbed rim or shopping for a full set.
