Collection: Genesis G90 Factory Wheels

The Genesis G90 is the brand's full-size flagship sedan, sitting above the G80 and G70 as the top of the Genesis lineup. The G90 was developed through two generations, with the first generation receiving a facelift before the redesigned RS4 generation: the original HI generation (2016 to 2019), the HI Facelift (2018 to 2022), and the RS4 generation that arrived for the 2023 model year in the U.S. The bolt pattern and center bore remain the same across these G90 periods, while lug thread size changes on the RS4 generation. Wheel diameter, width, and offset shift by trim, generation, and front-versus-rear position, particularly on the staggered setups used by upper trims. This guide covers the confirmed bolt pattern, center bore, and complete rim dimensions for the documented G90 configurations supported by the available source, along with how the factory wheel lineup has evolved since the model's launch.

Quick Specs at a Glance

What Size Wheels Does the Genesis G90 Have?

It depends on generation and trim. On the original HI generation (2016 to 2019), the base Premium trim used an 18x8 wheel with a 245/50R18 tire. The Elite trim moved to a staggered setup: a 19x8.5 front wheel with a 245/45R19 tire, paired with a wider 19x9.5 rear wheel and a 275/40R19 tire. The top Royal and Ultimate trims stepped up to a staggered setup with a 20x8.5 front wheel and a 245/40R20 tire, paired with a 20x9.5 rear wheel and a 275/35R20 tire.

The HI Facelift (2018 to 2022) carried a similar spread of tire sizes, including 245/50R18, 245/45R19, 245/50R19, 275/40R19, 245/40R20, 245/45R20, and 275/35R20 across its trim lineup, with confirmed rim widths ranging from 8.5 inches on the 19-inch wheels up to 9 inches on the 20-inch rear wheel. Exact ET values by individual trim were not consistently verified for this generation, so they are left out here rather than assumed from the HI or RS4 figures.

The redesigned RS4 generation (2023-present) starts with a non-staggered 19x8.5 wheel on the base 3.5T-GDi trim, running a 245/50R19 tire. Upper trims move to a staggered setup with a 20x8.5 front wheel and a 245/45R20 tire, paired with a 20x9.5 rear wheel and a 275/40R20 tire. The largest confirmed factory setup is a staggered 21x8.5 front wheel with a 245/40R21 tire, paired with a 21x9.5 rear wheel and a 275/35R21 tire.

What Is the Bolt Pattern on the Genesis G90?

Every Genesis G90, from the original HI generation through the RS4 generation introduced for 2023, uses a 5x114.3 bolt pattern with a 67.1mm center bore. Lug thread size differs by generation: the HI and HI Facelift generations use an M12 x 1.5 thread, while the RS4 generation moved to an M14 x 1.5 thread. A shared bolt pattern and center bore across generations does not by itself mean every factory wheel is a direct-fit match for every trim, since wheel width, offset, thread size, and front-versus-rear position all vary across the HI and RS4 lineups.

Genesis G90 Center Bore and Offset

Center bore is 67.1mm across every G90 generation confirmed in this guide. Offset varies by generation, trim, and wheel position: the HI generation ranges from ET30 on the Royal/Ultimate front wheel up to ET47 on the Elite rear wheel, while the RS4 generation uses ET31 on front wheels and ET45 on rear wheels across its staggered setups. Front and rear wheels on staggered configurations use different offsets, so the two positions should not be treated as interchangeable with each other.

Do G90 Wheels Interchange Between Generations?

Even where the G90 generations share basic hub specifications, their factory wheel dimensions can vary by generation, trim, and wheel position. Shared bolt pattern and center bore alone do not establish direct-fit interchangeability. The HI and HI Facelift generations use an M12 x 1.5 lug thread, while the RS4 generation uses M14 x 1.5, which is itself a meaningful fitment difference on top of the width and offset variation between trims. Within the HI generation, an Elite rear wheel (19x9.5, ET47) is a different wheel than a Royal/Ultimate rear wheel (20x9.5, ET45), and within the RS4 generation, front and rear wheels on any staggered setup are not interchangeable with each other. Matching your specific generation, trim, and wheel position matters as much as matching the bolt pattern.

About the Genesis G90

The Genesis G90 is the brand's full-size flagship sedan, positioned above the midsize G80 and compact G70. It's aimed at buyers cross-shopping the Mercedes-Benz S-Class and BMW 7 Series, drivers who want a traditional long-wheelbase luxury sedan with strong standard equipment and either rear-wheel-drive or all-wheel-drive availability.

The G90 launched for 2016 as Hyundai Motor Group's first standalone Genesis flagship, offered with V6 and V8 engine options depending on trim and market. A mid-cycle facelift arrived for 2018, updating exterior styling and technology while carrying the same core engine lineup forward through 2022. Genesis introduced the completely redesigned RS4 generation for the 2023 model year in the U.S., bringing updated styling, a revised interior, and a new factory wheel lineup.

The factory wheel lineup grew alongside the redesigns. The HI generation offered an 18x8 base wheel and two distinct staggered configurations: 19x8.5 front/19x9.5 rear on Elite trims and 20x8.5 front/20x9.5 rear on Royal and Ultimate trims. The RS4 generation carries a similar staggered logic forward but adds a 21x8.5 front/21x9.5 rear configuration on its top trim, giving the RS4-generation G90 the widest factory wheel range documented in this guide.

Vehicle Generations & Wheel Changes

The G90 has been through two generations and a mid-cycle facelift since its 2016 launch, and the bolt pattern and center bore have not changed across any of them, though lug thread size changed at the RS4 generation.

The single biggest thing to know: every Genesis G90, from the original HI generation through the RS4 generation introduced for 2023, uses the same 5x114.3 bolt pattern and 67.1mm center bore. Shared hub specifications do not establish direct-fit interchangeability on their own, since wheel width, offset, and lug thread size vary by generation, trim, and front-versus-rear position on the staggered setups.

OEM Wheel Sizes & Fitment by Year

Exact wheel sizes and offsets varied by trim and configuration, so treat these as the confirmed factory setups for each generation.

Genesis G90, HI (2016 to 2019)

Genesis G90, HI Facelift (2018 to 2022)

19x8.5 is the verified 19-inch wheel width for this generation. Documented tire configurations include 245/45R19 and 245/50R19, with 275/40R19 used on documented staggered rear configurations. Exact trim-specific wheel dimensions are not consistently verified, and per-trim offset values were not consistently verified either, so ET is omitted for this generation rather than estimated.

Why Choose Genuine OEM Wheels?

Genuine OEM wheels are designed around the G90's factory specifications, including fitment, load rating, brake clearance, and original styling. For most owners, the case for OEM comes up after a curbed rim or a pothole, when the goal is simply getting back to the exact fitment the G90 already had.

• Factory fit. Genuine OEM wheels are designed around the G90's factory bolt pattern, offset, and hub bore.
• Correct load rating. OEM wheels are designed to meet the factory specifications for the G90, including its required load rating.
• TPMS compatibility. Factory wheels are designed to accommodate the G90's original tire pressure monitoring system.
• Resale and appearance. A stock-style wheel keeps the G90 looking factory-correct, which matters if you plan to sell later.

OEM vs. Replica & Aftermarket Wheels

Some drivers choose replica wheels for their similar appearance or price. If your goal is to replace a damaged factory wheel, a genuine OEM wheel offers the best path to the correct fit, finish, and overall appearance, without the extra research replica shopping usually requires. We offer genuine OEM at replica price levels, often less. Here's how the two options typically compare:

How the G90 Compares

Shoppers cross-shopping the G90 typically also look at the Mercedes-Benz S-Class and the BMW 7 Series, both of which offer a similarly wide spread of factory wheel sizes across their own trim lineups. The G90's factory wheel range, from a 19x8.5 base setup up to a staggered 21x8.5 front and 21x9.5 rear setup on its top trim, sits in the same general territory as those rivals, though the exact bolt patterns and center bores differ between brands and are not interchangeable with G90 wheels.

Frequently Asked Questions

What size wheels does the Genesis G90 have?
It depends on generation and trim. On the HI generation: 18x8 on Premium, 19x8.5 front/19x9.5 rear on Elite, and 20x8.5 front/20x9.5 rear on Royal and Ultimate. On the RS4 generation: 19x8.5 (square) on the base 3.5T-GDi trim, 20x8.5 front/20x9.5 rear on upper trims, and 21x8.5 front/21x9.5 rear on the top trim.

What is the bolt pattern on the Genesis G90?
Every G90 uses a 5x114.3 bolt pattern with a 67.1mm center bore. This has been consistent across the HI, HI Facelift, and RS4 generations.

What is the center bore of the Genesis G90?
The G90's center bore is 67.1mm across every generation and trim confirmed in this guide.

What offset do Genesis G90 wheels use?
Offset varies by generation, trim, and wheel position, from ET30 on the HI Royal/Ultimate front wheel up to ET47 on the HI Elite rear wheel. The RS4 generation uses ET31 on front wheels and ET45 on rear wheels across its staggered setups. Front and rear wheels on staggered configurations use different offsets, so the two positions should not be treated as interchangeable.

Do Genesis G90 wheels interchange between generations?
The bolt pattern and center bore have stayed the same across every G90 generation, but that alone does not establish direct-fit interchangeability. The HI and HI Facelift generations use an M12 x 1.5 lug thread, while the RS4 generation uses M14 x 1.5, and wheel width and offset also differ enough between trims and generations that these should not be treated as automatic direct-fit replacements for one another.

What is the largest factory wheel size on the Genesis G90?
The largest confirmed factory wheel is the 21x9.5 rear wheel used in the RS4 top-trim staggered setup, paired with a 275/35R21 tire.

Are OEM Genesis G90 wheels better than replicas?
A genuine OEM wheel is designed around the factory fitment, TPMS requirements, and load rating, while keeping the G90's original appearance.

Final Thoughts

The Genesis G90's wheel fitment has one constant running through it: a 5x114.3 bolt pattern and 67.1mm center bore that have never changed, across the HI generation, the HI Facelift, or the RS4 generation introduced for 2023. The real variables are wheel width, offset, and lug thread size, since the RS4 generation moved to a larger M14 x 1.5 thread, and wheel width and offset differ meaningfully between the base square setups and the various staggered Elite, Royal, Ultimate, and RS4 trim configurations, including between the front and rear wheels within a single staggered set. Genuine OEM wheels remain the simplest way to get factory-correct fit and styling, whether replacing a curbed rim or shopping for a full set. For replacement purposes, the correct wheel should be matched to the G90's generation, trim, and wheel position.
