Collection: BMW 4-Series OEM Wheels

BMW spent late 2012 telling the world the coupe was leaving the 3 Series. The Concept 4 Series, shown that December, set out to replace the E92 3 Series coupe with a model line of its own, and the production F32 Coupe and F33 Convertible reached the U.S. for 2014, followed by the five-door F36 Gran Coupe for 2015. The 4 Series was meant to look lower and more deliberate than the sedan it grew from, and its wheels were part of that case: a plain 17x7.5 star-spoke on the base car, and 18x8 and 18x8.5 or 19x8 and 19x8.5 grey star-spokes on the sportier versions.

The second generation, introduced for 2021, answered with a large vertical kidney grille, wider tracks, and a different hub, 5x112 in place of 5x120. The wheels moved with it. The Gran Coupe reached the U.S. for 2022 on 18x8.5 wheels, and the Coupe and Convertible took bi-color M designs in Orbit Grey, Jet Black, and Cerium Grey. Read in order, the factory wheels show a restrained sporting coupe turning into a more assertive design. This guide covers both generations for U.S. cars and treats the M4 as a separate model.

Quick Specs at a Glance

First Generation BMW 4 Series: F32, F33 and F36

Development of the Original 4 Series

The F32 was designed under Nicolas Huet and arrived as BMW's first stand-alone coupe line. Against the 3 Series Coupe it replaced, it was half an inch longer and half an inch lower on a wheelbase almost two inches longer, a stretched, low stance that the base 17x7.5 wheel suited well. The F33 Convertible used a retractable hardtop and seated four, like the coupe. The F36 Gran Coupe added four doors and a rear hatch for five passengers, with the liftback profile giving it a longer roofline than the two-door cars. The U.S. lineup ran as the 428i and 435i through 2016 and the 430i and 440i from 2017 through 2020, with xDrive available.

Original Factory Wheel Styling

The first-generation wheels were built from a small vocabulary. The base Style 393 is a 17x7.5 star spoke at ET37, with a simple pattern that suited the restrained shape of the standard car. Style 397, an 18x8 double spoke at ET34 documented in Orbit Grey, added visual weight without changing the design language. The sporting wheels were the M Star-spoke designs: Style 400M, an 18-inch staggered wheel at 18x8 and 18x8.5, and Style 403M, a 19-inch staggered wheel at 19x8 and 19x8.5. Their twin-blade spokes gave the coupe the more purposeful look of an M Sport car.

BMW sold the 4 Series with Sport Line, Luxury Line, and M Sport appearance packages, but the package-to-style mapping for each U.S. model year was not independently verified, so this guide lists styles by size and offset instead of assigning them to a line. The documented dimensions are the same for the Coupe, Convertible, and Gran Coupe, and BMW part catalogs list the same styles across all three. Rear-wheel-drive and xDrive cars use the same wheels, and whether every package was sold on every body style was not verified.

Factory Colors and Finishes

Silver was the traditional finish, and the supplier listing for Style 393 shows it. Style 400M is documented in Ferric Grey, and Style 403M in Ferric Grey with a bright-turned face, a darker, machined treatment that marked the M Sport wheels. Gloss Black, Satin Black, and anthracite versions of these wheels appear in aftermarket refurbishment listings and are not treated as factory finishes.

First-Generation Facelift and Wheel Design Development

BMW's 2017 life-cycle update brought the 430i and 440i names, replacing the 428i and 435i with a 248-horsepower 2.0-liter four-cylinder and a 320-horsepower 3.0-liter six. The exterior changes were modest: bi-LED headlights as standard, LED fog lights, and full-LED tail lights. The update kept the original proportions and the overall identity of the car. No U.S. wheel-dimension change at the facelift was found. Parts catalogs for a 2019 F32 still list Styles 393, 397, 400M, and 403M, so the wheel range appears to have carried through the generation, although the availability of the 17-inch wheel past 2017 was not separately verified.

Second Generation BMW 4 Series: G22, G23 and G26

The New Design Direction

The G22 Coupe arrived for 2021 on the CLAR platform with a large, vertically prominent kidney grille, sculpted surfaces, and a wider stance. The G23 Convertible switched to a fabric roof, and one source gives 2021 as its first U.S. model year. The Gran Coupe followed for 2022 and grew 5.9 inches longer, 1 inch wider, and 2.1 inches taller than its predecessor, with tracks wider by 1.6 inches in front and 0.7 inches in the rear. The 4 Series was no longer a quiet cousin of the 3 Series. It had its own face, and its wheels got more elaborate to match.

How Factory Wheel Styling Changed

The G22 and G23 shifted to bi-color M wheels. Style 790M is an 18-inch M Double-spoke in Orbit Grey with a bright-turned face, sized 18x7.5 front and 18x8.5 rear. Styles 791M and 792M are 19-inch wheels in Jet Black and Cerium Grey with burnished faces, sized 19x8 front and 19x8.5 rear. The refreshed cars show Style 995M, a 19-inch M Double-spoke bicolor wheel, on the M440i, and the U.S. database lists the same 19x8 ET27 and 19x8.5 ET40 sizes for 2025, although the Style assignment for U.S. cars was not verified.

The Gran Coupe has its own set, per BMW's U.S. launch information. The 430i stands on 18-inch double-spoke bi-color Style 853 wheels, and the M440i xDrive on 18-inch M aerodynamic bi-color Style 858M wheels. M Sport and Dynamic Handling packages add 19-inch M Y-spoke Style 859M or aerodynamic Style 860M wheels, and the M440i xDrive Cooling and High-Performance Tire Package adds 19-inch M double-spoke Style 861M wheels with performance tires.

M Sport and M440i Wheel Designs

M Sport styling on the G-series is tied to the packages and the M440i. The M440i xDrive comes with M Sport brakes, M Sport suspension, and 18-inch wheels as standard, with 19-inch performance-tire wheels optional. M Sport brakes, a model-specific wheel, and darker finishes signal the M440i visually, though its documented U.S. wheel and tire sizes match the 430i on the Coupe and Convertible. The M4 has its own wheels and is not covered here.

Coupe, Convertible and Gran Coupe Applications

The G22 Coupe and G23 Convertible share the same documented wheels. The Gran Coupe uses wider ones: 18x8.5 at ET36 on a 245/45R18 tire, against 18x7.5 at ET25 on a 225/45R18 on the Coupe. BMW's launch press sheet lists 7.5x18 with 225/45R18 tires for the Gran Coupe, but wheel databases and Edmunds list 18x8.5 ET36 with 245/45R18 for U.S. cars, so the wider figure is used here. Gran Coupe offsets run from ET35 to ET42, and a Coupe wheel is not a like-for-like fit on a Gran Coupe, or the reverse, even though the bolt pattern and bore match. The electric i4 Gran Coupe is a separate model and its wheels are not covered.

How BMW 4 Series Wheel Styling Evolved Across Generations

The first-generation wheels matched the original coupe's restrained manner. The base 17x7.5 star spoke and the 18x8 double spoke had simple, quiet patterns that suited a long, low body. BMW drew a line between standard and sporting cars with the M Star-spoke wheels, whose twin-blade spokes and darker Ferric Grey finish, and the staggered 8 and 8.5-inch widths, gave Sport and M Sport versions a different stance from the base car.

The facelift kept that formula, and the changes were in lighting and badging, not in the wheels. The second generation moved to a more aggressive design language. The wheels became bi-color, with Orbit Grey, Jet Black, and Cerium Grey bodies and bright-turned or burnished faces, and the Gran Coupe brought M aerodynamic and Y-spoke patterns. The more complex designs suited a body with a larger grille, sharper creases, and a wider track. By the Style 995M refresh, the 19-inch M double-spoke had become a signature of the M440i. Finishes grew more varied across the generation, and the wheel became a part of how each 4 Series version was told apart.

From Traditional Silver to Modern Bi-Color Finishes

First-generation finishes were mostly single-tone. Silver covered the standard wheels, and the Style 400M and Style 403M carried Ferric Grey, the latter with a bright-turned face. Spoke shapes did most of the work in telling the cars apart, and wheel color supported an understated design.

The G-series made color a feature. Orbit Grey, Jet Black, and Cerium Grey bodies meet bright-turned or burnished faces on Styles 790M, 791M, and 792M, and the Gran Coupe's Styles 853 through 861M are all bi-color. Darker bodies and machined faces interact with the newer bodywork by sharpening the contrast between spoke and gap on a wheel that is large in the arch. Only the finishes confirmed for a specific style are named here, and the exact colors of Styles 858M to 861M were not verified.

How the 4 Series' Development Influenced Its Factory Wheels

The original 4 Series was a low coupe, and a 17x7.5 wheel filled its arch without crowding it. As trims moved up, diameter grew to 18 and 19 inches and widths to 8 and 8.5. Staggered packages added a wider rear wheel, which gives the car a planted look from behind. The second generation's revised proportions and wider tracks lifted base wheels to 18-inch size and, on the Gran Coupe, to 8.5 and 9 inches wide. M Sport designs became more prominent as the cars did, with bi-color finishes and more complex spoke patterns. Wheel design was part of the car's styling development, and the documented evidence here is about dimensions and appearance, not performance.

BMW 4 Series OEM Wheel Fitment by Generation, Body Style and Package

BMW 4 Series Factory Wheel Styles, Colors and Finishes

Wheel Widths, Offsets and Fitment

Both generations use a mix of square and staggered setups. On the F-series, the 17x7.5 and 18x8 wheels are square, while the 18x8 and 18x8.5 and 19x8 and 19x8.5 packages are staggered. The G22 and G23 offer a square 18x7.5 and staggered 18x7.5 and 18x8.5 or 19x8 and 19x8.5. The G26 documents a square 18x8.5 and staggered 18x8.5 and 18x9 or 19x8.5 and 19x9.

Offsets vary by wheel and axle. Rear offsets are higher than front on every staggered package, such as ET47 against ET34 on the F-series 18-inch set and ET40 against ET25 on the G22 and G23, so a rear wheel is not just a wider front wheel. Factory tire sizes follow the wheel, from 225/50R17 on the base F-series to 255/35ZR19 on its 19-inch rear and 245/45R18 on the Gran Coupe. Width is taken from the wheel specification, not inferred from the tire. The standard and M Sport differences are in diameter and width, not hub: both generations use the same lug thread, M14x1.25.

5x120 vs. 5x112: Understanding the Generation Change

F-series cars use a 5x120 bolt pattern and a 72.6mm center bore, and G-series cars use 5x112 and 66.6mm, so a wheel from one generation will not mount on the other. Offsets differ too, with the G22 and G23 18-inch front at ET25 against ET34 on the F-series. Fitment within a generation depends on bolt pattern, center bore, width, offset, tire size, and body style together, and a matching bolt pattern alone does not establish correct OEM fitment.

BMW 4 Series OEM vs. Replica 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:

BMW 4 Series Wheel Fitment Questions

What Factory Wheel Sizes Were Available on the BMW 4 Series?

F-series cars (2014-2020) used a 17x7.5 base wheel, an 18x8 square wheel, and staggered 18x8 and 18x8.5 or 19x8 and 19x8.5 sets. G22 and G23 cars (2021-2027) use 18x7.5 square or 18x7.5 and 18x8.5 staggered, with 19x8 and 19x8.5 optional. The G26 Gran Coupe uses 18x8.5 square or staggered 18x8.5 and 18x9, and 19x8.5 and 19x9.

Do the First- and Second-Generation 4 Series Use the Same Bolt Pattern?

No. The F32, F33, and F36 use 5x120 with a 72.6mm center bore. The G22, G23, and G26 use 5x112 with a 66.6mm center bore. Both use M14x1.25 lug bolts.

Are 4 Series Coupe and Gran Coupe Wheels Identical?

On the first generation, the documented wheels are the same across body styles. On the second generation, they differ: the G22 Coupe uses 18x7.5 at ET25, and the G26 Gran Coupe uses 18x8.5 at ET36, with wider 19-inch wheels as well.

What Is the Difference Between Standard and M Sport Factory Wheels?

On the F-series, M Sport wheels are the Style 400M and 403M star-spokes in staggered sizes and Ferric Grey, while the base car runs a 17x7.5 Style 393. On the G-series, M Sport and M440i wheels are bi-color M designs, most at 19 inches, against an 18-inch standard wheel.

How Did BMW 4 Series Wheel Designs Change Between Generations?

The first generation used single-tone star-spoke and double-spoke wheels in silver and grey. The second moved to bi-color M designs with bright-turned or burnished faces, and the Gran Coupe added M aerodynamic and Y-spoke patterns.

Final Thoughts

The 4 Series began as a restrained, low coupe and became a bolder, more distinctive car, and its factory wheels changed with it, from silver and grey star-spokes at 5x120 to bi-color M designs at 5x112. Matching generation, body style, trim, diameter, width, offset, bolt pattern, center bore, and tire size is what keeps a replacement factory-correct, and it is how Finish Line Wheels approaches a 4 Series order.
