The 2015 BMW 750Li sits in the modern luxury-sedan tradition where long-wheelbase comfort, high-speed composure, and substantial road presence all matter just as much as straight-line power. On a car like this, tire selection is tied closely to the exact wheel package, because the 750Li uses several radial fitments across 18-inch, 19-inch, and 20-inch rims. Some setups are square, while the M Sport package can also use a staggered front-and-rear arrangement. Available choices range from blackwall performance-oriented tires to redline and raised white letter alternatives in certain sizes, so the right pick depends on the car's actual sub-model, wheel diameter, and the kind of appearance you want.
Which Tire Size Is Right for The 2015 BMW 750Li
The 2015 BMW 750Li uses five primary tire sizes, and the right one depends on the exact sub-model and wheel package. These are all radial fitments, but they span 18-inch, 19-inch, and 20-inch rims, including both square and staggered layouts. Before choosing a tire, confirm whether the car is a Base or M Sport configuration and verify the actual wheel diameter currently on the vehicle.
245/45R19 is a modern metric radial size in which 245 is the section width in millimeters, 45 is the aspect ratio, and 19 is the wheel diameter in inches. On the 2015 BMW 750Li, this size is part of a 19-inch radial fitment and appears across more than one configuration, making it one of the key sizes to verify before ordering. Available choices include blackwall tires from BFGoodrich and Nitto in series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size is a strong comparison point if the car wears 19-inch wheels and you want to sort through brand, series, and road-use character within that fitment.
245/50R18 uses the same 245-millimeter section width as some other 750Li fitments, but with a taller 50-series profile on an 18-inch wheel. It is a radial size associated with the 18-inch setup, so it matters most on cars that retain that wheel diameter rather than later wheel-package changes. Product choices in this size include Pro-Trac Street Pro III options with raised white letter and redline sidewall treatments, giving the tire a more distinctive presentation than a typical blackwall-only selection. This is the size to evaluate when the car has 18-inch rims and appearance is part of the decision along with fitment.
245/40R20 is a modern metric radial with a 245-millimeter section width, a shorter 40-series profile, and a 20-inch rim diameter. On the 2015 BMW 750Li, it serves as a front fitment in the 20-inch M Sport staggered arrangement rather than a universal size across every version. Choices in this size include blackwall performance-oriented offerings from BFGoodrich and Nitto, along with Pro-Trac Street Pro III options in raised white letter and redline form. This size deserves careful attention when matching the front axle on a 20-inch setup, especially if the car must retain the intended staggered arrangement.
275/35R20 is a wider modern metric radial size, with 275 millimeters of nominal section width, a 35-series profile, and a 20-inch rim diameter. On the 2015 BMW 750Li, it is used as the rear fitment in the 20-inch M Sport staggered combination, so it works as part of a front-and-rear pair rather than as a standalone decision. Available products include blackwall selections from BFGoodrich and Nitto, plus Pro-Trac Street Pro III choices in raised white letter and redline sidewalls. This is the size to confirm when the rear axle carries 20-inch M Sport wheels and maintaining the proper staggered balance is important.
275/40R19 is a wide metric radial that combines a 275-millimeter section width with a 40-series profile on a 19-inch wheel. For the 2015 BMW 750Li, it functions as the rear size in the 19-inch M Sport staggered arrangement, making it a rear-specific fitment rather than a one-size solution for the whole car. Product choices are centered on blackwall performance radials from BFGoodrich and Nitto, including series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size should be chosen only after confirming that the car uses the 19-inch staggered M Sport setup.
Tire fitment on the 2015 BMW 750Li varies by sub-model and wheel setup rather than following one universal size across the entire range. Checking the exact Base or M Sport configuration matters first, and wheel diameter matters just as much because this car uses 18-inch, 19-inch, and 20-inch arrangements.

2015 BMW 750Li Base
The 2015 BMW 750Li Base uses a square radial fitment with either an 18-inch or 19-inch size depending on the wheel package on the car. That makes wheel confirmation the first step, followed by choosing among available sidewall treatments and product series within the correct diameter.
The 2015 BMW 750Li M Sport uses a 19-inch radial fitment in 245/45R19 for this configuration. Tire selection then centers on comparing the available blackwall product lines in that size and making sure the car has not been changed to a different wheel setup.
The 2015 BMW 750Li M Sport Front uses either a 19-inch or 20-inch radial front size depending on the wheel package. Front tire selection should stay tied to the actual front wheel diameter so the tire matches the intended staggered setup and preserves proper front-to-rear sizing balance.
The 2015 BMW 750Li M Sport Rear uses the wider rear tire sizes associated with either the 19-inch or 20-inch staggered arrangement. Rear tire choice needs to follow the car's exact wheel diameter and should be matched carefully to the corresponding front size already on the vehicle.
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 questions for a 2015 BMW 750Li usually come down to sub-model fitment, wheel diameter, staggered versus square setups, and the difference between available brands, series, and sidewall styles. These answers focus on selecting the correct radial size and checking the car before road use.
Tire Size & Fitment
What tire size fits a 2015 BMW 750Li?
A 2015 BMW 750Li can use 245/50R18, 245/45R19, 245/40R20, 275/40R19, or 275/35R20, depending on the exact sub-model and wheel package. All of these are radial sizes, and the car may be equipped with either a square setup or a staggered M Sport arrangement with different front and rear sizes.
The right starting point is the actual wheel diameter on the car, followed by whether it is a Base or M Sport configuration. A 19-inch square setup is different from a 19-inch or 20-inch staggered setup, so checking both the front and rear tire sizes already on the vehicle helps prevent ordering the wrong combination.
What size rim does a 2015 BMW 750Li use?
The 2015 BMW 750Li uses 18-inch, 19-inch, and 20-inch rim diameters, depending on the tire size and sub-model. The 245/50R18 fits an 18-inch wheel, 245/45R19 and 275/40R19 fit 19-inch wheels, and 245/40R20 plus 275/35R20 fit 20-inch wheels.
Rim diameter should be confirmed before anything else because several 750Li sizes have similar overall dimensions but mount on different wheel diameters. Looking only at tread width is not enough. Check the size molded on the current tire and confirm front and rear wheels separately if the car may have a staggered M Sport setup.
Why does the 2015 BMW 750Li have more than one tire size?
The 2015 BMW 750Li has more than one tire size because fitment changes with sub-model and wheel package. Base models can use either an 18-inch or 19-inch square fitment, while M Sport versions can also use staggered arrangements that pair narrower front tires with wider rear tires.
That means tire selection is tied to the exact configuration on the car rather than the model name alone. A buyer should verify whether the car has matching front and rear wheel sizes or a staggered layout, and then confirm that any replacement tire matches the wheel diameter and axle position it is intended for.
Choosing the Right Tire
What should I consider when choosing a 2015 BMW 750Li tire?
Start with the exact size already used on the car, because the 2015 BMW 750Li spans multiple radial fitments across 18-inch, 19-inch, and 20-inch wheels. After size and axle position are confirmed, compare the available tire series, sidewall style, rim-width specification where stated, and any load details that appear for that size.
A square Base setup and a staggered M Sport setup lead to different buying decisions. Some sizes focus on blackwall performance-oriented choices, while others also include redline or raised white letter options. The best comparison is the one that keeps the correct wheel diameter and matches how the car is actually used and presented.
What sidewall styles are available for 2015 BMW 750Li tires?
Sidewall style depends on the tire size chosen for the 2015 BMW 750Li. Blackwall options are available in several 19-inch and 20-inch sizes, while certain Pro-Trac Street Pro III sizes are also offered with raised white letter and redline sidewall treatments.
That makes sidewall choice more than a cosmetic afterthought, because it can narrow the field to a particular size and series. Buyers who want a traditional blackwall look have several choices, while those looking for a more customized presentation should first make sure the preferred sidewall style is offered in the exact size their wheel package requires.
What brands offer tires for the 2015 BMW 750Li?
Tires for the 2015 BMW 750Li are available from BFGoodrich, Nitto, and Pro-Trac across the covered sizes. Depending on the fitment, the available series include g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, NT555 G2, and Street Pro III.
Brand choice should come after fitment is settled, not before. Some sizes offer a broader mix of brands and series than others, and some also add redline or raised white letter styling through Pro-Trac. Comparing by exact size first makes it easier to evaluate the real differences in presentation and product character.
Restoration & Appearance
Which tire should I choose for a period-style 2015 BMW 750Li?
A period-style approach on a 2015 BMW 750Li starts with keeping the correct wheel diameter and tire size for the car's actual configuration. Since this is a modern luxury sedan with all-radial fitments, the closest period-style choice usually comes from selecting the right contemporary size first and then choosing a sidewall treatment that matches the look you want.
Blackwall tires suit the original-era character of many late-model luxury cars, while redline or raised white letter options create a more customized presentation in certain sizes. Appearance should never override correct fitment. If exact as-delivered originality matters, compare the car against marque-specific documentation before choosing a nonstandard sidewall treatment.
How does tire construction affect the appearance of a restored 2015 BMW 750Li?
On a 2015 BMW 750Li, construction does not create a bias-ply-versus-radial decision because the vehicle uses radial tire fitments throughout. Appearance is influenced more by the sidewall style, the selected tire series, and whether the car retains its intended 18-inch, 19-inch, or 20-inch wheel package.
That shifts the visual decision toward blackwall, redline, or raised white letter styling where those options exist. Wheel diameter also shapes the overall stance, especially on M Sport cars with staggered fitments. Keeping the correct front and rear size relationship is usually more important to the finished look than changing between radial constructions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 BMW 750Li?
Yes, modifications can affect tire fitment on a 2015 BMW 750Li, especially because this model already uses several wheel diameters and, in some versions, staggered front and rear sizes. Aftermarket wheels, suspension changes, or previous package swaps can move the car away from its original fitment pattern even when the model badge remains the same.
A careful check should include the size stamped on each current tire, the wheel diameter at each axle, and whether the front and rear widths match or differ. Clearance at the fender, steering lock, and suspension should also be reviewed whenever the car has been lowered, re-wheeled, or otherwise altered from stock configuration.
What should I inspect before driving a 2015 BMW 750Li on new tires?
Before driving a 2015 BMW 750Li on new tires, make sure the installed size matches the wheel diameter and axle position, especially on M Sport staggered setups. Check inflation pressure, confirm proper rotation direction if applicable, and inspect for even bead seating, adequate valve condition, and any sign of rubbing at full steering lock.
A short road test should be followed by another visual inspection. Watch for vibration, unusual pull, or contact marks that suggest a mismatch between tire, wheel, and vehicle setup. It also helps to recheck pressure after the first drive and confirm that front and rear sizes were not accidentally mixed on a staggered arrangement.
What should I check before a longer drive in a 2015 BMW 750Li?
Before a longer drive in a 2015 BMW 750Li, inspect tread condition, sidewalls, and inflation pressure on all four tires, and verify that the car is wearing the correct front and rear sizes for its wheel package. On staggered M Sport cars, confirm that the wider rear tires are still on the rear axle and that wheel diameters match side to side.
Longer trips also make it worthwhile to look for weather checking, puncture repairs, uneven wear, and any slow air loss that might go unnoticed around town. A 750Li places real demands on its tires at highway speed, so size accuracy, good condition, and stable pressure matter just as much as brand or sidewall style.
