The 2022 BMW Z4 is a modern rear-drive roadster that blends BMW’s long-running sports-car tradition with contemporary chassis tuning, turbocharged power, and staggered wheel-and-tire setups. Tire selection matters here because this Z4 uses several metric radial sizes across 18-inch and 19-inch rims, with front and rear fitment varying by sub-model and wheel package. That makes the first decision less about brand loyalty and more about confirming whether the car is an sDrive30i or M40i, and whether it is on 18s or 19s. Available choices then branch into blackwall, redline, and raised white letter options, along with several performance-oriented radial series.
Which Tire Size Is Right for The 2022 BMW Z4
The 2022 BMW Z4 uses five primary tire sizes, and the right one depends on both sub-model and axle position. Front and rear sizes are staggered, and this car uses both 18-inch and 19-inch rim diameters, so the first step is confirming whether the car is an sDrive30i or M40i and checking the wheel diameter before comparing tire options.
255/35R19 is a metric radial size with a 255-millimeter section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2022 BMW Z4, this size serves as a front fitment on M40i and can also appear on the front of sDrive30i models equipped with 19-inch wheels. Available choices center on BFGoodrich performance-oriented radial lines, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all in blackwall form. This size is the right place to start when the car has a 19-inch front wheel and a staggered setup needs to be preserved.
Fit(s): M40i Front, sDrive30i Front, and sDrive30i Rear
Construction: Radial|Rim: 18 in
255/40R18 is a metric radial size with a 255-millimeter section width, a 40-series profile, radial construction, and an 18-inch rim diameter. On the 2022 BMW Z4, it appears as the M40i front fitment and also as an sDrive30i size, including rear use in some 18-inch staggered combinations. BFGoodrich offers this size across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A blackwall tires, giving buyers several performance-focused series within the same fitment. This size deserves a careful check because it can serve different positions depending on the exact Z4 configuration.
275/35R19 is a metric radial size with a 275-millimeter section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2022 BMW Z4, it is used as a rear fitment on M40i models and on sDrive30i cars equipped with the corresponding 19-inch rear wheel. Product choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2, all with blackwall sidewalls. This is the size to verify when the Z4 has a 19-inch rear wheel and the wider rear portion of the staggered setup needs to remain intact.
275/40R18 is a metric radial size with a 275-millimeter section width, a 40-series profile, radial construction, and an 18-inch rim diameter. On the 2022 BMW Z4, this size is used at the rear on M40i models with 18-inch wheels and also on sDrive30i rear applications using the same rim diameter. Choices are broader here, with BFGoodrich, Nitto, and Pro-Trac options, plus blackwall, redline, and raised white letter sidewall treatments. This size is especially relevant for buyers who want to keep the rear staggered width while choosing between a more understated or more appearance-driven sidewall presentation.
225/45R18 is a metric radial size with a 225-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim diameter. On the 2022 BMW Z4, it is used on the front of sDrive30i models with the 18-inch wheel setup, making it distinct from the wider M40i front fitments. BFGoodrich and Nitto both offer options in this size, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2, all in blackwall form. This size should be chosen only after confirming that the car is an 18-inch sDrive30i front application rather than a 19-inch setup.
Sub-model fitment on the 2022 BMW Z4 is not one-size-fits-all because tire selection changes by trim, axle position, and wheel diameter. Identifying whether the car is an sDrive30i or M40i, then confirming front versus rear and 18-inch versus 19-inch wheels, is the key step before choosing a tire.

2022 BMW Z4 M40i Front
The 2022 BMW Z4 M40i front fitment uses either an 18-inch or 19-inch radial tire, depending on the wheel setup on the car. Front tire selection starts with confirming wheel diameter, then choosing among the available blackwall performance radial series in the matching size.
The 2022 BMW Z4 M40i rear fitment uses a wider staggered radial size than the front, again split between 18-inch and 19-inch wheel packages. Rear tire choice should preserve that staggered layout while matching the actual rim diameter and the appearance or series preference you want.
The 2022 BMW Z4 sDrive30i front fitment can use either an 18-inch or 19-inch radial size, with the narrower 225/45R18 front setup distinct from the wider 19-inch alternative. That makes wheel confirmation especially important before comparing brands or performance-oriented tire series.
The 2022 BMW Z4 sDrive30i rear fitment uses wider rear radial sizes that vary with the wheel package on the car. Selecting the correct rear tire means confirming both the rim diameter and the staggered rear application rather than matching only the model name.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2022 BMW Z4?
The 2022 BMW Z4 uses 225/45R18, 255/40R18, 275/40R18, 255/35R19, and 275/35R19 radial tire sizes. The exact size depends on sub-model, axle position, and wheel package, because this Z4 uses a staggered setup with different front and rear sizes rather than one universal fitment.
The practical step is to verify whether the car is an sDrive30i or M40i, then confirm whether you are replacing a front or rear tire and whether the wheel is 18 or 19 inches. Matching only the year and model is not enough on a Z4 with staggered sizing, especially if the car has been changed from its original wheel setup.
What size rim does a 2022 BMW Z4 use?
The 2022 BMW Z4 uses both 18-inch and 19-inch rim diameters. Tire fitment is tied directly to that wheel diameter, with 225/45R18, 255/40R18, and 275/40R18 built for 18-inch rims, while 255/35R19 and 275/35R19 are built for 19-inch rims.
Wheel diameter should be confirmed before comparing tread pattern, brand, or sidewall style. A tire sized for an 18-inch wheel cannot be mounted on a 19-inch rim, and the Z4’s staggered front and rear arrangement means the correct diameter still has to be matched to the correct axle position.
Why does the 2022 BMW Z4 have more than one tire size?
The 2022 BMW Z4 has more than one tire size because fitment changes by sub-model, wheel package, and front-versus-rear position. Both sDrive30i and M40i applications use staggered radial sizing, and the car can appear with either 18-inch or 19-inch wheels depending on configuration.
That means tire selection starts with the car’s exact setup instead of the model name alone. Looking at the existing tire sidewall, confirming wheel diameter, and checking whether you are replacing a front pair or rear pair will narrow the choice quickly and help avoid mixing sizes that do not belong on the same arrangement.
Choosing the Right Tire
What should I consider when choosing a 2022 BMW Z4 tire?
Start with the exact size, axle position, and wheel diameter your 2022 BMW Z4 uses. This car’s tire choice is driven by staggered front and rear fitment, and the available options are all radial designs, so the real comparison is among size-correct performance series, sidewall styling, rim-width compatibility, and load details where they are stated.
After size is confirmed, think about how the car is used and how you want it to look. A blackwall tire keeps the appearance understated, while redline or raised white letter styling on 275/40R18 creates a more expressive rear presentation. Matching the tire to the actual wheel and intended use matters more than choosing by brand name alone.
What sidewall styles are available for 2022 BMW Z4 tires?
Most available 2022 BMW Z4 tires are blackwall radials, which is the only sidewall style offered in several supported sizes. The one size with broader appearance choice is 275/40R18, where blackwall, redline, and RWL options are available among the supported radial products.
Sidewall styling should always come after confirming the correct size for the car’s position and wheel diameter. On a Z4, that is especially important because front and rear fitments differ, and appearance choices that exist in one rear size may not exist in the matching front size or in the alternate 19-inch package.
What brands offer tires for the 2022 BMW Z4?
BFGoodrich appears across all five supported 2022 BMW Z4 sizes, while Nitto is available in several of the 18-inch and 19-inch applications. Pro-Trac appears in 275/40R18, where it adds alternative sidewall treatments that are not present in every other supported size.
Brand choice should be made only after the size and wheel package are confirmed. Some sizes have a deeper mix of brands and series than others, so the right comparison is not simply brand versus brand, but which products are actually available for the exact front or rear fitment on your specific Z4 setup.
Restoration & Appearance
Which tire should I choose for a period-style 2022 BMW Z4?
A period-style approach for a 2022 BMW Z4 still begins with the correct modern radial size for the car’s sub-model, axle position, and wheel diameter. Since this is a contemporary roadster rather than an older restoration-era vehicle, the appearance decision usually comes down to keeping a clean blackwall presentation or selecting one of the more expressive rear sidewall options available in 275/40R18.
Blackwall tires will suit the most restrained, factory-inspired look on most Z4s, especially in the BFGoodrich and Nitto performance series. If appearance is part of the goal, confirm first that the car actually uses 275/40R18 at the rear before considering redline or raised white letter treatments, since those choices do not extend across every supported size.
How does tire construction affect the appearance of a restored 2022 BMW Z4?
Tire construction is straightforward on the 2022 BMW Z4 because the supported fitments are radial. That means the visual difference is less about choosing bias-ply versus radial and more about selecting the correct low-profile metric size, preserving the intended staggered stance, and choosing the sidewall treatment that fits the look you want.
The biggest appearance mistake on a modern Z4 is usually incorrect sizing rather than the wrong construction type. A mismatched front-to-rear combination or the wrong wheel diameter can alter the car’s visual balance quickly, so maintaining the proper size relationship across the axles is more important here than pursuing a vintage-style tire presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 BMW Z4?
Yes, modifications can affect tire fitment on a 2022 BMW Z4. Aftermarket wheels, suspension changes, altered ride height, spacer use, or body changes can all change how much room the tire has, even when the size matches one of the supported radial fitments for the original wheel-and-tire layout.
A modified Z4 should be checked for wheel diameter, wheel width, and clearance at the fender, suspension, and steering range before a new tire is chosen. On a staggered car, those checks matter at both axles because the front and rear do not share the same dimensions or always use the same rim diameter.
What should I inspect before driving a 2022 BMW Z4 on new tires?
Before driving a 2022 BMW Z4 on new tires, inspect the wheel size, confirm the tire is mounted in the correct front or rear position, and look for proper clearance around suspension and bodywork. It is also smart to verify inflation, inspect for visible mounting damage, and make sure the staggered arrangement matches the car’s intended setup.
A short initial road test helps confirm there is no rubbing, vibration, or uneven steering response. Recheck pressure after the first drives, and keep an eye on the rear tires in particular, since wider rear fitments on a Z4 can make a size mismatch or wheel issue more obvious under normal road use.
How often should tires on a 2022 BMW Z4 be inspected?
Tires on a 2022 BMW Z4 should be inspected regularly, not only when tread looks low. Collector-kept and fair-weather cars can age out tires before they wear out, so pressure, tread condition, sidewall cracking, cuts, bulges, and slow air loss all deserve routine attention even when the car is driven sparingly.
A quick visual check before a drive and a more careful inspection at regular service intervals are both sensible habits. Because the Z4 uses staggered sizing, comparing wear from front to rear can also reveal alignment or setup issues sooner, especially on cars with performance tires and low-profile sidewalls.
