The 2023 BMW M240i xDrive sits in the modern compact performance coupe category, blending BMW’s traditional six-cylinder character with all-wheel-drive traction and a chassis that rewards precise setup. On a car like this, tire choice has a direct effect on balance, steering response, and everyday road manners. This application uses 19-inch radial sizes, with a staggered fitment structure that includes 225/40R19, 245/35R19, and 255/35R19 depending on position. Available options center on blackwall performance radials from BFGoodrich and Nitto across several g-Force and NT555 series choices. The key is confirming whether the car needs the front, rear, or single coupe size before comparing tread style, rim-width compatibility, and intended use.
Which Tire Size Is Right for The 2023 BMW M240i xDrive
The 2023 BMW M240i xDrive uses three primary tire sizes, all in radial construction on 19-inch rims. The most important first step is identifying whether you are selecting for the coupe overall reference, the front position, or the rear position, because this fitment uses different widths across the application. Once that is settled, the decision becomes comparing available performance tire series, brand options, and wheel-width compatibility within the correct size.
225/40R19 is a metric radial size where 225 is the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2023 BMW M240i xDrive, this size serves as part of the 19-inch radial fitment and appears in both coupe and front-position applications. Available choices include BFGoodrich blackwall tires in the g-Force Comp 2 AS and g-Force Phenom T/A series. This size is the one to evaluate when replacing the narrower front-oriented fitment or matching a setup that calls for the 225-width tire.
245/35R19 is a metric radial size with a 245-millimeter section width, a 35-series profile, and a 19-inch rim diameter. For the 2023 BMW M240i xDrive, it is tied to the front-position coupe fitment and represents a wider front tire choice within the same 19-inch wheel family. Product options include blackwall radials from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the size to check when the car is equipped with the wider front setup and you want to preserve that steering and clearance relationship.
255/35R19 is a metric radial size in which 255 gives the nominal width in millimeters, 35 is the aspect ratio, and 19 identifies the wheel diameter. On the 2023 BMW M240i xDrive, this size is used at the rear, where the broader footprint is part of the staggered arrangement. BFGoodrich offers several blackwall choices here, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This rear size deserves careful attention when replacing only two tires, since maintaining the intended front-to-rear relationship matters on a performance-oriented xDrive coupe.
Sub-model fitment on the 2023 BMW M240i xDrive is tied more to vehicle position than trim variation, and the sizes are not all the same across the covered applications. Checking whether you are replacing the coupe reference size, the front tires, or the rear tires is essential before choosing a tire.

2023 BMW M240i xDrive Coupe
The 2023 BMW M240i xDrive Coupe is associated with the 225/40R19 radial size. That makes selection fairly straightforward if this is the configuration being matched, with the main comparison points being tire series, blackwall performance options, and wheel-width suitability.
The 2023 BMW M240i xDrive Coupe Front uses two 19-inch radial sizes within the covered fitment set, so the exact front setup needs to be confirmed before replacement. That matters because a 225-width front tire and a 245-width front tire do not represent the same wheel and stance combination.
The 2023 BMW M240i xDrive Coupe Rear uses the 255/35R19 radial size. Rear-tire replacement should preserve the intended width relationship with the front tires, while also confirming wheel width and clearance if the car has been changed from its current setup.
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 2023 BMW M240i xDrive?
The 2023 BMW M240i xDrive uses three 19-inch radial tire sizes across this application: 225/40R19, 245/35R19, and 255/35R19. These sizes are not interchangeable references for every position, because the fitment includes coupe, front, and rear-specific use within the same model range.
The practical step is to confirm where the tire is being installed before ordering a replacement. A front axle may use a different width than the rear, and replacing only one pair on a staggered setup calls for extra attention to wheel width, tire dimensions, and the existing front-to-rear combination already on the car.
What size rim does a 2023 BMW M240i xDrive use?
The covered tire sizes for the 2023 BMW M240i xDrive all use a 19-inch rim diameter. That applies to 225/40R19, 245/35R19, and 255/35R19, so the wheel diameter stays consistent even though tire width and profile vary by position within the fitment.
Rim diameter is only part of the check, especially on a performance coupe with staggered sizing. Wheel width still matters, and the available products show different recommended width ranges depending on tire size. Confirm the actual wheel setup on the car before replacing tires, particularly if aftermarket wheels have been installed.
Why does the 2023 BMW M240i xDrive have more than one tire size?
More than one tire size appears on the 2023 BMW M240i xDrive because the fitment is position-sensitive. The application includes 225/40R19 and 245/35R19 for front-related use and 255/35R19 for the rear, which reflects a staggered performance-oriented arrangement rather than one uniform size at all four corners.
That means tire selection starts with identifying the exact location and current setup on the car. Replacing a rear 255/35R19 with a front size, or assuming every M240i xDrive uses the same front width, can create avoidable fitment issues. Matching the existing wheel and axle arrangement is the safest starting point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 BMW M240i xDrive?
Start with the correct size and position on the car, since the 2023 BMW M240i xDrive uses multiple 19-inch radial sizes. After that, compare tire series, brand, wheel-width compatibility, and any load-related details that appear in the available product choices for 225/40R19, 245/35R19, or 255/35R19.
This car is sensitive to tire setup, so the right choice depends on whether you are replacing fronts, rears, or a full set. A buyer trying to preserve the current balance should also compare the existing tires already on the car, especially if the vehicle has a staggered arrangement or wheels that differ from stock dimensions.
What brands offer tires for the 2023 BMW M240i xDrive?
BFGoodrich and Nitto offer tires within the covered fitment range for the 2023 BMW M240i xDrive. BFGoodrich appears across all three sizes with several g-Force series choices, while Nitto is represented in 245/35R19 through the NT555 G2 line.
Brand is only one part of the decision on this application. It still helps to compare the exact tire series offered in the size you need, because availability differs between the narrower front size, the wider front option, and the rear fitment. That keeps the selection focused on the axle and wheel setup actually being replaced.
What tire series are available for the 2023 BMW M240i xDrive?
The available series for the 2023 BMW M240i xDrive include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, BFGoodrich g-Force Sport Comp 2, and Nitto NT555 G2. Not every series appears in every size, so the exact choices depend on whether you need 225/40R19, 245/35R19, or 255/35R19.
Series differences matter because they shape what you are actually comparing in the product grid. Rather than choosing by name alone, match the tire series to the correct axle position, verify the wheel-width range where it is stated, and keep the front and rear pairing consistent with the car’s present configuration.
Restoration & Appearance
Does correct tire fitment matter for a 2023 BMW M240i xDrive restoration or preservation project?
Yes. Even on a modern performance coupe like the 2023 BMW M240i xDrive, correct tire fitment matters if the goal is preserving the car’s intended stance and driving character. The covered setup uses specific 19-inch radial sizes that vary by position, so the wrong width or profile can change how the car presents and responds.
A preservation-minded owner should begin by documenting the wheel and tire combination currently on the car, then replacing like with like unless there is a clear reason to change it. That approach helps maintain a consistent appearance and avoids introducing mismatch between front and rear tire proportions on a staggered application.
How does tire construction affect the appearance of a preserved 2023 BMW M240i xDrive?
Tire construction is straightforward on the 2023 BMW M240i xDrive because the covered fitment is radial throughout. That keeps the appearance conversation centered less on bias-ply versus radial differences and more on choosing the correct size, sidewall profile, and width relationship across the 19-inch front and rear setup.
Since the available products are all blackwall radials, the visual difference comes mainly from preserving the proper stagger and avoiding mismatched sizing. A car intended to retain a clean, contemporary BMW presentation benefits from maintaining the correct front and rear proportions rather than mixing tire sizes simply because they share the same rim diameter.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 BMW M240i xDrive?
Yes. Modifications can affect tire fitment on a 2023 BMW M240i xDrive even when the tire still has the correct 19-inch rim diameter. Changes to wheel width, wheel offset, suspension height, alignment settings, or body clearance can all influence whether a 225/40R19, 245/35R19, or 255/35R19 setup remains suitable.
A car with aftermarket wheels or suspension changes should be measured from the actual hardware on the vehicle, not from assumptions based on model name alone. Clearance at the fender, inner wheelhouse, and steering range deserves attention, especially when replacing only one axle or moving between the two front-size possibilities.
What should I inspect before driving a 2023 BMW M240i xDrive on new tires?
Before road use, inspect the wheel diameter and width, confirm the new tires match the intended front or rear position, and check that inflation is set correctly for the tire and vehicle setup. It is also smart to look over valve stems, wheel condition, and the existing alignment if the old tires showed uneven wear.
A short, careful test drive can reveal rubbing, vibration, or steering pull before the car returns to normal use. On a staggered performance coupe, it also helps to confirm that left and right tires match across the axle and that the rear pair remains consistent with the wider rear fitment the car is using.
How often should tires on a 2023 BMW M240i xDrive be inspected?
Tires on a 2023 BMW M240i xDrive should be inspected regularly, not just when tread looks worn. Frequent checks for uneven wear, sidewall damage, punctures, and air loss are worthwhile on a performance-oriented car, especially one using low-profile 19-inch tires with different front and rear sizes.
Cars that are driven less often still deserve routine inspection because age, storage conditions, and extended parking can affect tire condition. Looking over the tires before longer drives is a sensible habit, and any sign of cracking, bulging, persistent pressure loss, or contact marks should be addressed before the car is used at speed.
