The 2015 BMW 740Li sits in the modern long-wheelbase luxury sedan class, where ride quality, quiet highway manners, and confident high-speed composure matter just as much as style. On this chassis, tire selection is tied closely to wheel package and trim, with radial fitments spanning 18-, 19-, and 20-inch rims. That makes the real decision less about old-versus-new construction and more about confirming the exact sub-model and front or rear size before choosing among blackwall, redline, or raised white letter options in several performance-oriented series. For a stock sedan or a more appearance-conscious setup, wheel diameter and staggered fitment deserve careful attention first.
Which Tire Size Is Right for The 2015 BMW 740Li
The 2015 BMW 740Li uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Fitment varies across 18-inch, 19-inch, and 20-inch rims, and M Sport applications can also introduce separate front and rear sizes. The first step is confirming whether the car is Base or M Sport, then verifying wheel diameter before comparing tread style, sidewall treatment, or tire series.
245/45R19 is a metric radial size with a 245-millimeter section width, a 45-series profile, and a 19-inch rim diameter. On the 2015 BMW 740Li, this size appears across multiple configurations, making it one of the key fitments to verify before narrowing product choice. Available options include BFGoodrich and Nitto blackwall tires in g-Force and NT555 G2 series. This is a useful size to evaluate when the car wears 19-inch wheels and the goal is to balance correct fitment with the preferred tread and sidewall presentation.
245/50R18 is a metric radial size that combines a 245-millimeter section width with a taller 50-series sidewall on an 18-inch rim. For the 2015 BMW 740Li, it serves as a distinct wheel-package fitment rather than a general replacement for the other sizes on this page. Current choices center on Pro-Trac Street Pro III tires offered with raised white letter or redline sidewalls. This size deserves attention when the car retains 18-inch wheels and the owner wants to keep that wheel diameter while choosing a more specific visual style.
245/40R20 is a metric radial size with a 245-millimeter section width, a lower 40-series profile, and a 20-inch rim diameter. On the 2015 BMW 740Li, this size is used as a front fitment in certain M Sport applications, so it should not be treated as a universal four-corner size without checking the car's setup. BFGoodrich, Nitto, and Pro-Trac options are available, including blackwall, raised white letter, and redline styles across several series. This size is the right place to start when a 20-inch front wheel package is already confirmed.
275/35R20 is a metric radial size that pairs a wider 275-millimeter section width with a 35-series profile on a 20-inch rim. For the 2015 BMW 740Li, it appears as a rear fitment in certain M Sport combinations, giving it a specific role in a staggered setup rather than a standard all-around application. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings in blackwall, raised white letter, and redline styles. This size should be chosen only after confirming that the car uses the matching 20-inch rear wheel and staggered rear fitment.
275/40R19 is a metric radial size with a 275-millimeter section width, a 40-series profile, and a 19-inch rim diameter. On the 2015 BMW 740Li, it serves as a rear fitment in certain M Sport applications, so its wider footprint is part of a staggered arrangement rather than a one-size-fits-all choice. Available blackwall options include several BFGoodrich g-Force series tires along with the Nitto NT555 G2. This size is most relevant when the car already uses a 19-inch rear wheel package and rear-specific fitment needs to be preserved.
Sub-model fitment on the 2015 BMW 740Li is not one-size-fits-all, because wheel diameter and tire size vary between Base and M Sport applications. Checking the exact sub-model matters first, and M Sport cars also need front and rear fitment confirmed before selecting tires.

2015 BMW 740Li Base
The 2015 BMW 740Li Base uses either a 245/45R19 or 245/50R18 radial tire, depending on the wheel package on the car. That means tire selection starts with confirming whether the sedan has 18-inch or 19-inch wheels, then comparing available sidewall styles and tire series within the correct size.
The 2015 BMW 740Li M Sport uses a 245/45R19 radial tire in this configuration. With only one primary size tied to this sub-model, the main decision shifts toward brand, tire series, and whether a blackwall presentation suits the car's intended road use and appearance.
The 2015 BMW 740Li M Sport Front uses either 245/40R20 or 245/45R19, depending on which wheel setup is on the vehicle. Front tire selection should stay tied to the confirmed rim diameter, especially on a performance-oriented luxury sedan where staggered fitment and visual balance matter.
The 2015 BMW 740Li M Sport Rear uses either 275/35R20 or 275/40R19, again depending on the wheel package fitted to the car. Rear tire choice should follow the existing staggered setup closely so wheel diameter and front-to-rear fitment remain consistent.
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 the 2015 BMW 740Li usually come down to wheel diameter, sub-model identification, and whether the car uses a staggered M Sport setup. The FAQs below focus on exact size fitment, tire selection, appearance choices, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2015 BMW 740Li?
The 2015 BMW 740Li uses several radial tire sizes: 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20. The correct size depends on whether the car is a Base or M Sport model and, in M Sport form, whether the tire is for the front or rear axle.
The key is to confirm the exact wheel package before choosing a tire. A 740Li with 18-inch wheels calls for a different size than one on 19s or 20s, and staggered M Sport setups use different front and rear widths. Checking the current wheel diameter and matching axle position prevents ordering by model name alone.
What size rim does a 2015 BMW 740Li use?
The 2015 BMW 740Li uses 18-inch, 19-inch, and 20-inch rim diameters, depending on the configuration. The 245/50R18 fits an 18-inch rim, the 245/45R19 and 275/40R19 fit 19-inch rims, and the 245/40R20 and 275/35R20 fit 20-inch rims.
Rim diameter is the first fitment detail to verify because these sizes are not interchangeable across different wheel diameters. Once the wheel size is confirmed, the next step is matching the correct tire width and aspect ratio to the front or rear position. That matters even more on M Sport cars that may use a staggered setup.
Why does the 2015 BMW 740Li have more than one tire size?
More than one tire size appears on the 2015 BMW 740Li because fitment changes with trim and wheel package. Base models can use either 245/50R18 or 245/45R19, while M Sport applications may use 19-inch or 20-inch combinations, including wider rear tires such as 275/40R19 or 275/35R20.
That variety means the model badge alone is not enough to choose tires accurately. Looking at the sub-model, then checking the actual wheel diameter and whether the car has matching or staggered tires, will narrow the selection quickly. On cars that have changed hands, the wheel currently installed is often the most important clue.
Choosing the Right Tire
What should I consider when choosing a 2015 BMW 740Li tire?
Start with the correct size for the exact 2015 BMW 740Li configuration, then compare construction details within that fitment. Every primary size here is radial, so the decision usually comes down to wheel diameter, axle position, tire series, sidewall treatment, and any rim-width specification tied to the tire being considered.
A Base sedan on 18-inch wheels calls for a different approach than an M Sport car with staggered 20-inch fitment. It also helps to think about how the car is used: daily road miles, seasonal cruising, or a more appearance-driven setup. Choosing within the correct size first keeps style or brand preference from overriding fitment.
What sidewall styles are available for 2015 BMW 740Li tires?
Sidewall choices for the 2015 BMW 740Li include blackwall, redline, and raised white letter styles, depending on tire size. Blackwall options appear across the BFGoodrich and Nitto fitments, while certain Pro-Trac Street Pro III sizes add redline and raised white letter alternatives.
The right sidewall style depends on the character you want the car to project. Blackwall keeps a modern, understated look, while redline or raised white letter creates a more noticeable custom presentation. Sidewall appearance should always come after confirming the correct size, since not every style is offered in every 740Li fitment.
What brands offer tires for the 2015 BMW 740Li?
Tires for the 2015 BMW 740Li are available from BFGoodrich, Nitto, and Pro-Trac. Depending on size, those brands cover several series, including BFGoodrich g-Force variants, Nitto NT555 G2, and Pro-Trac Street Pro III, with differences in sidewall styling and rim-width specifications.
Brand choice should be secondary to exact fitment, especially because the 740Li spans three rim diameters and several wheel-package combinations. Once the right size is established, comparing series and sidewall style becomes more useful than comparing brand names by themselves. That approach keeps the selection tied to the car's actual setup.
Restoration & Appearance
Which tire should I choose for a period-style 2015 BMW 740Li?
A period-style 2015 BMW 740Li still starts with the exact radial size that matches the car's wheel package, whether that is 245/50R18, 245/45R19, 245/40R20, 275/40R19, or 275/35R20. From there, the visual direction comes from tire series and sidewall treatment rather than from switching to an earlier tire construction.
For a restrained factory-inspired look, blackwall options usually keep the presentation closest to a contemporary luxury sedan. Redline or raised white letter styles create a more customized appearance and can change the visual character of the car significantly. Matching the tire's look to the wheel package helps the sedan appear intentional rather than mixed.
How does tire construction affect the appearance of a restored 2015 BMW 740Li?
On the 2015 BMW 740Li, construction is straightforward because the primary fitments are radial. That means the visible appearance difference comes less from bias-ply versus radial choice and more from the tire's sidewall design, series, and the way the selected size fills the wheel opening on 18-, 19-, or 20-inch wheels.
A blackwall radial generally preserves a cleaner modern luxury look, while redline or raised white letter styling gives the car a more customized visual theme. Buyers pursuing exact originality should also compare their wheel package and trim presentation against marque-specific references. On a car from this era, construction choice is usually less of an appearance issue than sidewall style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 BMW 740Li?
Yes, modifications can affect tire fitment on a 2015 BMW 740Li, especially because the car already uses multiple wheel diameters and may have staggered M Sport sizing. Aftermarket wheels, suspension changes, or altered ride height can change the clearance relationship around sizes like 245/40R20 and 275/35R20.
The safest approach is to verify the actual wheel diameter and width currently on the car, then inspect clearance at the fenders, suspension, and steering range before changing sizes. Even when a tire matches the general model fitment, a modified setup can narrow the margin. That is particularly important on low-profile combinations.
What should I inspect before driving a 2015 BMW 740Li on new tires?
Before driving a 2015 BMW 740Li on new tires, inspect the wheel size, confirm front and rear tire positions, and check that the installed size matches the car's current setup. It also helps to look over valve stems, wheel condition, visible suspension wear, and basic tire condition after installation and inflation.
A short recheck after the first few miles is worthwhile, particularly on staggered M Sport cars where front and rear sizes differ. Uneven clearance, rubbing, or a mismatch between tire and wheel package is easier to correct early. Keeping pressures consistent and watching for vibration or air loss helps verify that the installation is settled properly.
What should I check before a longer drive in a 2015 BMW 740Li?
Before a longer drive, make sure the 2015 BMW 740Li is wearing the correct tire size for its wheel package and that tread, sidewalls, and inflation are in good condition. Look for cracking, cuts, bulges, irregular wear, or slow air loss, especially on a sedan that may spend periods parked between outings.
Longer trips put more emphasis on consistency across all four corners, or across the correct front and rear pairs on a staggered car. It is also smart to inspect for clearance issues if wheels or suspension have ever been changed. Starting with a careful walk-around often catches small problems before they become roadside interruptions.
