The 2024 BMW M850i xDrive sits at the sharp end of BMW’s grand touring lineup, blending modern luxury, substantial V8 performance, and all-wheel-drive confidence in both coupe and convertible form. It is the kind of car where tire choice has a direct effect on stance, response, and overall road feel. This model uses a staggered radial setup, with different front and rear sizes and either 19-inch or 20-inch wheel diameters depending on the wheel package. Available choices center on modern blackwall performance radials from BFGoodrich and Nitto across several series. The key is matching the exact front or rear size and confirming the wheel diameter before comparing tire character and intended use.
Which Tire Size Is Right for The 2024 BMW M850i xDrive
The 2024 BMW M850i xDrive uses four primary tire sizes across a staggered front-and-rear setup, and those sizes also split between 19-inch and 20-inch wheel packages. The first step is confirming whether the car has 19-inch or 20-inch wheels, then matching the correct front and rear sizes, since this is not a one-size-fits-all fitment.
245/35R20 is a metric radial size with a 245-millimeter section width, a 35-series aspect ratio, and fitment for a 20-inch rim. On the 2024 BMW M850i xDrive, this size is used in the front position on the 20-inch setup, where precise steering response and proper staggered balance matter. Available choices include BFGoodrich and Nitto blackwall radials across g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. This size should be chosen only when the car is equipped with the 20-inch front wheel package and the wheel width matches the tire’s approved range.
245/40R19 is a metric radial size that uses a 245-millimeter section width, a 40-series profile, and a 19-inch rim diameter. On the 2024 BMW M850i xDrive, it serves as the front tire size for the 19-inch configuration, making wheel-diameter confirmation essential before selection. BFGoodrich offers this size in several blackwall performance radial series, including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. It is the right direction for owners keeping the 19-inch front setup and comparing choices by series character, rim-width compatibility, and road-use priorities.
275/30R20 is a metric radial size with a 275-millimeter section width, a low 30-series profile, and a 20-inch rim fitment. On the 2024 BMW M850i xDrive, this is the rear size paired with the 20-inch front fitment, so it plays a critical role in maintaining the car’s staggered layout. The available product choice in this size is a blackwall Nitto NT555 G2 radial. It should be evaluated as part of a complete 20-inch front-and-rear setup, with attention to wheel diameter, rear wheel specifications, and clearance on any car that has been modified from stock.
275/35R19 is a metric radial size that combines a 275-millimeter section width with a 35-series profile for a 19-inch rim. On the 2024 BMW M850i xDrive, it fills the rear position on the 19-inch staggered setup, so it must be matched with the corresponding 19-inch front size rather than treated as a standalone choice. Products in this size include blackwall offerings from BFGoodrich and Nitto across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. It makes sense for cars wearing 19-inch rear wheels and for buyers comparing series differences within the correct rear fitment.
Fitment stays consistent in concept across the covered M850i xDrive coupe and convertible configurations, but tire selection still depends on wheel diameter and front-versus-rear position. Checking the exact sub-model position matters because this BMW uses a staggered setup rather than the same size at all four corners.

2024 BMW M850i xDrive Convertible Front
The 2024 BMW M850i xDrive Convertible Front uses either a 245/35R20 or 245/40R19 radial depending on the wheel package. Tire selection starts with confirming whether the convertible has 20-inch or 19-inch front wheels, then comparing the available blackwall performance radial choices in that exact size.
The 2024 BMW M850i xDrive Convertible Rear uses either a 275/30R20 or 275/35R19 radial to match the staggered rear fitment. Choosing correctly means confirming wheel diameter first and then matching the rear size to the corresponding front setup rather than mixing 19-inch and 20-inch pairings.
The 2024 BMW M850i xDrive Coupe Front uses a 245-section front radial in either 245/35R20 or 245/40R19, depending on the wheel diameter. That makes the front wheel package the key checkpoint before comparing tire series, rim-width specifications, and the intended balance between summer-oriented and all-season-style choices.
The 2024 BMW M850i xDrive Coupe Rear carries the wider rear fitment, using either 275/30R20 or 275/35R19. Rear tire selection should stay aligned with the coupe’s wheel diameter and front pairing so the staggered setup remains consistent in both appearance and fitment.
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.

Owners of a 2024 BMW M850i xDrive usually need answers about staggered tire sizing, 19-inch versus 20-inch wheel fitment, front and rear matching, and how to compare the available radial performance tire choices. These FAQs focus on those exact decisions.
Tire Size & Fitment
What tire size fits a 2024 BMW M850i xDrive?
The 2024 BMW M850i xDrive uses a staggered radial setup with four primary sizes: 245/35R20 and 275/30R20 for the 20-inch package, or 245/40R19 and 275/35R19 for the 19-inch package. The narrower 245-section sizes are used in front, while the wider 275-section sizes are used in the rear.
That means the first thing to confirm is wheel diameter, followed by front-versus-rear position. A tire that is correct for the front will not be correct for the rear, and a 19-inch setup should not be mixed with a 20-inch setup. On any car with aftermarket wheels, wheel width and clearance should also be checked before choosing replacement tires.
What size rim does a 2024 BMW M850i xDrive use?
A 2024 BMW M850i xDrive uses either 19-inch or 20-inch rims, depending on the wheel package. The 19-inch setup pairs 245/40R19 front tires with 275/35R19 rear tires, while the 20-inch setup pairs 245/35R20 fronts with 275/30R20 rears.
Rim diameter is the most important fitment checkpoint on this model because the tire sizes are tied directly to either the 19-inch or 20-inch package. The next step is matching the front and rear sizes correctly within that package. If the car has replacement wheels, verify the actual wheel markings before ordering tires rather than relying only on appearance.
Why does the 2024 BMW M850i xDrive have more than one tire size?
The 2024 BMW M850i xDrive has more than one tire size because it uses a staggered setup and was fitted with either 19-inch or 20-inch wheel diameters. That creates one pair of front and rear sizes for the 19-inch configuration and another pair for the 20-inch configuration.
This is normal for a high-performance grand touring car, but it means the exact setup must be confirmed before replacing tires. Front and rear sizes should stay in their intended positions, and the wheel diameter has to match the tire’s rim diameter. A modified suspension or non-original wheels can change clearance, so those details are worth checking at the same time.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 BMW M850i xDrive?
Start with the exact tire size and position on the car, since the 2024 BMW M850i xDrive uses different front and rear sizes and comes with either 19-inch or 20-inch wheels. From there, compare the available radial choices by tire series, approved rim-width range where stated, load figures where given, and the kind of driving the car actually sees.
A buyer choosing between available options is really deciding how to balance fitment accuracy with tire character. Some series lean toward performance-focused presentation, while others offer a different all-season-style direction. The best comparison comes after confirming wheel diameter, front or rear placement, and whether the car still uses its original wheel and suspension setup.
What brands offer tires for the 2024 BMW M850i xDrive?
Tires for the 2024 BMW M850i xDrive are available from BFGoodrich and Nitto in the covered sizes. Depending on the exact front or rear fitment, choices include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2 products.
Brand selection matters less than choosing the correct size for the correct wheel package and axle position. Once that is settled, compare each tire by its series, construction details, and any stated rim-width or load specification that applies to the size you need. Rear-size selection can look narrower in some fitments, so matching availability to the car’s actual setup is important.
What tire series are available for the 2024 BMW M850i xDrive?
The available tire series for the 2024 BMW M850i xDrive include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in every size, so the exact front or rear fitment determines which choices are available.
Series names are useful because they help separate the options once the correct size has been identified. A front 245-section fitment may offer several series choices, while one rear size may have fewer. That makes it worthwhile to confirm the tire’s position on the car first, then compare the available series by intended use and wheel compatibility.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 BMW M850i xDrive?
Yes, modifications can affect tire fitment on a 2024 BMW M850i xDrive even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body changes can all influence clearance at the fender, suspension, and steering components.
That is especially important on a staggered car with low-profile 19-inch or 20-inch tires. A modified setup may need more careful checking than a stock one because a tire that matches the nominal size still has to clear under load and steering movement. Measuring the actual wheels and inspecting clearance at both front and rear is the smart approach.
What should I inspect before driving a 2024 BMW M850i xDrive on new tires?
Before driving a 2024 BMW M850i xDrive on new tires, inspect tire pressure, bead seating, valve stems, wheel condition, and the direction and position of each tire in the staggered setup. It also helps to confirm that the front and rear sizes match the wheel package so a 19-inch and 20-inch fitment are not mixed accidentally.
A short visual and physical check can prevent most early fitment problems. Look for adequate clearance at the strut, inner liner, and fender edge, then recheck pressure after the first drive. If the car has been stored, driven infrequently, or recently modified, a more complete inspection of alignment, suspension wear, and wheel hardware is worthwhile.
How often should tires on a 2024 BMW M850i xDrive be inspected?
Tires on a 2024 BMW M850i xDrive should be inspected regularly, with air pressure checked frequently and the tire surfaces examined for cuts, punctures, uneven wear, bulges, and sidewall damage. Because this BMW uses low-profile staggered radials, small issues can have a noticeable effect on ride quality and handling.
A practical routine is to inspect the tires before longer drives and anytime the car has been parked for an extended period. Keep an eye on wear differences between the front and rear positions, since the staggered layout means they are doing different jobs. Any sign of repeated pressure loss or abnormal wear deserves prompt attention.
