The 2023 BMW M240i blends compact BMW coupe proportions with modern turbocharged performance, making tire selection a real part of how the car feels on the road. Its chassis, steering response, and everyday drivability all depend on staying with the right 19-inch radial fitment. This application uses 225/40R19, 245/35R19, and 255/35R19 sizes, so the first step is confirming whether the car is using a square or staggered setup and which axle you are buying for. Available choices center on blackwall radial performance tires from BFGoodrich and Nitto across several series. Getting the right size and axle position matters as much as choosing the tread style itself.
Which Tire Size Is Right for The 2023 BMW M240i
The 2023 BMW M240i uses three 19-inch radial tire sizes, and the right choice depends on the exact wheel position and sub-model fitment. Before selecting a tire, confirm whether the car is using the single 225/40R19 fitment or the staggered Coupe Front and Coupe Rear arrangement, since the front and rear sizes are different even though the rim diameter stays the same.
225/40R19 is a modern metric radial size where 225 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2023 BMW M240i, this size serves as a 19-inch performance-oriented fitment and also appears as the front size in one Coupe configuration. Product choices in this size include BFGoodrich options in the g-Force Comp 2 AS and g-Force Phenom T/A series, both with blackwall styling. This size is the one to evaluate when matching a front axle requirement or maintaining the narrower 19-inch setup used on certain M240i configurations.
245/35R19 is a modern metric radial size with a 245-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. For the 2023 BMW M240i, this size appears in the Coupe Front fitment and should be treated as a front-axle-specific choice rather than a universal size for every configuration. Available tires include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2, all in blackwall form. This is the size to focus on when replacing front tires on a staggered M240i and keeping the intended front-to-rear relationship intact.
255/35R19 is a modern metric radial size in which 255 refers to nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 19 is the wheel diameter. On the 2023 BMW M240i, this size is used in the Coupe Rear position, making it part of a staggered fitment rather than a one-size setup. BFGoodrich offers several choices here, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all with blackwall sidewalls. This size deserves extra attention when replacing rear tires so the car keeps the correct rear fitment and wheel-width relationship.
Sub-model fitment on the 2023 BMW M240i is tied closely to wheel position rather than a simple one-size answer. Checking the exact Coupe, Coupe Front, or Coupe Rear designation matters because the tire size changes across those configurations even though all use 19-inch radial tires.

2023 BMW M240i Coupe
The 2023 BMW M240i Coupe uses the 225/40R19 radial size as its primary fitment. Tire selection here is mainly about choosing the right performance-oriented blackwall option while confirming that the car is not using the separate front and rear staggered arrangement.
The 2023 BMW M240i Coupe Front fitment uses 19-inch radial tires and includes the narrower front-side sizing used on a staggered setup. Selecting for this position means verifying the exact front size on the car and keeping the front axle matched correctly to the rear fitment.
The 2023 BMW M240i Coupe Rear fitment uses 255/35R19 as the rear tire size. That makes rear tire selection less about broad compatibility and more about maintaining the intended staggered setup, wheel-width suitability, and front-to-rear balance already established on the car.
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.
Best 2023 BMW M240i Tires for Sale
Available 19-inch M240i tire choices center on BFGoodrich and Nitto radial performance offerings. Across the three sizes, the main comparison points are tire series, blackwall-only presentation, axle-specific sizing, and rim-width compatibility within each individual fitment.
These FAQs focus on the exact tire sizes used on the 2023 BMW M240i, how the front and rear fitments differ, and what to compare when choosing among available 19-inch radial tires.
Tire Size & Fitment
What tire size fits a 2023 BMW M240i?
The 2023 BMW M240i uses 225/40R19, 245/35R19, and 255/35R19 tire sizes, all in radial construction on 19-inch rims. The key point is that these sizes do not all serve the same position, since some M240i configurations use a staggered arrangement with different front and rear tires.
A replacement decision starts with checking the exact axle position and current wheel setup on the car. Matching the tire to the correct front or rear application is more important here than simply knowing that all three sizes belong somewhere within the 2023 M240i fitment range.
What size rim does a 2023 BMW M240i use?
The 2023 BMW M240i tire sizes in this application all use a 19-inch rim diameter. That applies to 225/40R19, 245/35R19, and 255/35R19, so the wheel diameter remains consistent even when the tire width and profile change between configurations or axle positions.
Rim diameter is only one part of the fitment picture, so it is still worth confirming the actual wheel width before choosing a tire. A 19-inch wheel can still vary in width front to rear, especially on a staggered performance coupe, and that affects which specific tire is appropriate.
Why does the 2023 BMW M240i have more than one tire size?
More than one tire size appears on the 2023 BMW M240i because the fitment can vary by configuration and wheel position. The car uses 225/40R19 in one overall Coupe fitment, while staggered Coupe Front and Coupe Rear positions use different sizes to create a front-to-rear tire relationship.
That means the correct replacement choice depends on more than the vehicle badge alone. Checking whether the car has matching tires all around or a staggered setup with different front and rear sizes will keep you from ordering a tire that belongs to the wrong axle.
Choosing the Right Tire
What should I consider when choosing a 2023 BMW M240i tire?
Start with the exact tire size and axle position, since the 2023 BMW M240i uses more than one 19-inch radial size. After that, compare the available series, wheel-width compatibility, and any load information shown for the size you need, especially if the car uses a staggered front-and-rear arrangement.
Appearance is straightforward here because the available choices are blackwall performance radials, so the main differences are construction details within each series and how each tire matches your intended use. A careful size check matters most, followed by wheel width and overall setup confirmation before installation.
What brands offer tires for the 2023 BMW M240i?
The available tires for this 2023 BMW M240i application come from BFGoodrich and Nitto. BFGoodrich appears across all three sizes in multiple g-Force series, while Nitto is available in 245/35R19 through the NT555 G2, giving buyers a second brand choice in that front-size fitment.
Brand choice should still come after confirming the correct size for the car's exact position and setup. Once the axle fitment is settled, comparing series, rim-width suitability, and any stated load specifications will tell you more than the brand name alone when narrowing the choices.
What tire series are available for the 2023 BMW M240i?
The 2023 BMW M240i tire options here include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, BFGoodrich g-Force Sport Comp 2, and Nitto NT555 G2. Those series are spread across the three 19-inch sizes, with some appearing in multiple fitments and others tied to a specific size.
Series selection matters once the correct tire size is confirmed, because not every series is available in every M240i position. Comparing by size first, then by series, helps keep the process practical and avoids choosing a tire line that may not exist in the front or rear size you actually need.
Restoration & Appearance
Does correct tire fitment matter for a 2023 BMW M240i restoration or collector presentation?
Yes, correct tire fitment still matters even on a modern performance coupe like the 2023 BMW M240i. The right size preserves the intended stance and front-to-rear visual relationship, especially if the car uses the staggered 245/35R19 front and 255/35R19 rear arrangement rather than a single-size setup.
Appearance choices are narrower here than on vintage vehicles because the available options are blackwall radials, not a mix of whitewall or stripe treatments. For a clean collector presentation, keeping the correct size at each wheel position and avoiding mismatched profiles usually has more visual impact than changing tire brand or series.
How does tire construction affect the appearance of a 2023 BMW M240i?
The 2023 BMW M240i fitments here are all radial tires, which suits the car's modern design and low-profile 19-inch wheel package. In visual terms, the construction choice is less about bias-ply versus radial character and more about preserving the intended modern sidewall height and width relationship at each corner.
Because these M240i options are all blackwall radials, appearance differences come mostly from selecting the correct size and maintaining the front or rear application the car requires. A tire that belongs to the wrong axle can change the car's look noticeably, even before any handling or clearance issues show up.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 BMW M240i?
Yes, modifications can affect tire fitment on a 2023 BMW M240i even when the replacement tire matches one of the correct factory-size patterns. Aftermarket wheels, width changes, offset changes, lowering springs, or suspension alterations can all change how a 225/40R19, 245/35R19, or 255/35R19 tire sits in the wheel opening.
That makes it important to check more than the sidewall size before ordering replacements. Confirm the actual wheel dimensions on the car, inspect clearance at full steering lock, and make sure front and rear tires still match the intended axle positions if the M240i is running a staggered setup.
What should I inspect before driving a 2023 BMW M240i on new tires?
Before driving a 2023 BMW M240i on new tires, confirm that the correct size is mounted at each wheel position and that the 19-inch tires seat properly on the wheels being used. It is also smart to inspect for visible sidewall damage, bead issues, uneven wheel condition, and any obvious interference points around suspension or fender areas.
Air pressure should be set correctly for the installed tires, and the car should be checked for vibration or rubbing during the first miles of use. On a staggered M240i, pay especially close attention to front-versus-rear placement so a rear tire does not end up on the front axle, or the reverse.
How often should tires on a 2023 BMW M240i be inspected?
Tires on a 2023 BMW M240i should be inspected regularly, not just when tread looks low. A quick visual check for punctures, sidewall cuts, cracking, bulges, and uneven wear is worthwhile throughout the year, especially on a performance-oriented car using low-profile 19-inch radial tires.
A more careful inspection makes sense before longer drives and any time handling changes or air loss appear. Cars that spend time parked should also have their tires checked for age-related condition and flat spotting, since even a lightly driven M240i can develop tire issues long before the tread is gone.
