The 2017 BMW 750i sits in BMW’s full-size luxury sedan range, blending long-wheelbase comfort, modern technology, and the kind of high-speed composure expected from a flagship German car. Tire choice on this model is more configuration-dependent than on many collector-era vehicles, because the 750i appears with multiple primary radial sizes across 18-, 19-, and 20-inch wheel fitments, including staggered front and rear applications. That makes wheel diameter and exact position on the car especially important before choosing a replacement. Available options range from blackwall performance-oriented radials to raised white letter and redline alternatives in select sizes. The right pick depends on keeping the correct size relationship while matching the car’s current wheels and intended road use.
Which Tire Size Is Right for The 2017 BMW 750i
The 2017 BMW 750i uses five primary tire sizes, and the first step is confirming the exact wheel setup on the car. Fitment varies by sub-model and by front-versus-rear position, with radial tires used on 18-, 19-, and 20-inch rims. Once the correct size is identified, the real choice becomes comparing tire series, sidewall style, and wheel-compatibility details within that exact fitment.
245/45R19 is a metric radial size in which 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. On the 2017 BMW 750i, this size is part of the vehicle’s primary radial fitment and appears in 19-inch applications. Available choices include BFGoodrich and Nitto blackwall tires across g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. This size is worth evaluating when the car is equipped with 19-inch wheels and a non-staggered front fitment that calls for this dimension.
245/50R18 is a metric radial size with a 245-millimeter nominal width, a 50-series profile, radial construction, and an 18-inch rim requirement. It represents one of the standard radial fitments used on the 2017 BMW 750i and is associated with 18-inch wheel setups. In this size, the visible choice is less about brand variety and more about sidewall presentation, with Pro-Trac Street Pro III options offered in raised white letter and redline form. It is the size to focus on when the car remains on its 18-inch wheels and the goal is matching that existing rim diameter first.
245/40R20 is a metric radial size that combines a 245-millimeter nominal width with a lower 40-series profile on a 20-inch rim. For the 2017 BMW 750i, this size serves as a front-position fitment in 20-inch applications, so it should not be treated as a universal four-corner size without checking the vehicle’s exact setup. Buyers can compare BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments available in this size. It becomes the correct path when the car has 20-inch front wheels and a staggered arrangement that requires a narrower front tire than the rear.
275/35R20 is a metric radial size with a wider 275-millimeter nominal section width, a 35-series profile, and a 20-inch rim diameter. On the 2017 BMW 750i, this size is used in 20-inch rear applications, making it part of a staggered setup rather than a one-size-fits-all replacement. Product choices include BFGoodrich, Nitto, and Pro-Trac, and sidewall styling ranges from blackwall to raised white letter and redline depending on the tire line. This is the size to evaluate when the rear of the car carries 20-inch wheels and the wider rear fitment needs to be preserved.
275/40R19 is a metric radial size that uses a 275-millimeter nominal width, a 40-series profile, and a 19-inch rim. On the 2017 BMW 750i, it appears as a rear-position fitment in 19-inch staggered applications, so it should be matched to the rear wheel and not assumed to belong at all four corners. BFGoodrich and Nitto options are available here, primarily in blackwall form, with several g-Force series choices alongside the NT555 G2. This size matters when the car is running 19-inch rear wheels and the owner needs to maintain the proper front-to-rear fitment relationship.
Sub-model fitment on the 2017 BMW 750i is not one-size-fits-all, because some configurations use a square setup while others use separate front and rear tire sizes. Checking the exact sub-model and wheel position matters before selecting a replacement, especially when 19-inch and 20-inch staggered combinations are involved.

Tire Size & Fitment
What tire size fits a 2017 BMW 750i?
The 2017 BMW 750i uses several primary tire sizes: 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20. All are radial fitments, and the correct one depends on the wheel package and, in staggered applications, whether the tire is for the front or rear of the car.
The most important first step is checking the actual wheel diameter and whether the car uses the same size at all four corners or a staggered setup. A 19-inch or 20-inch 750i can use different front and rear sizes, so the current wheel arrangement should be confirmed before choosing a replacement tire.
What size rim does a 2017 BMW 750i use?
The 2017 BMW 750i appears with 18-inch, 19-inch, and 20-inch rim diameters, depending on configuration. The 245/50R18 tire fits an 18-inch rim, 245/45R19 and 275/40R19 fit 19-inch rims, and 245/40R20 and 275/35R20 fit 20-inch rims.
Matching tire size to rim diameter is non-negotiable, so the wheel itself should be confirmed before anything else. On this BMW, rim diameter also helps identify whether the car has a square arrangement or a staggered front-and-rear setup, which affects how the front and rear tires should be replaced.
Why does the 2017 BMW 750i have more than one tire size?
The 2017 BMW 750i has more than one tire size because it was fitted with different wheel packages, including 18-inch, 19-inch, and 20-inch applications. Some configurations also use staggered sizing, where the front and rear tires are intentionally different widths and profiles.
That means the correct replacement is tied to the car’s present wheel setup, not just the model name. Checking the sidewall on the existing tires, confirming the wheel diameter, and noting whether the rear tire is wider than the front will keep the replacement search pointed at the right fitment.
Choosing the Right Tire
What should I consider when choosing a 2017 BMW 750i tire?
Start with the exact tire size and wheel position, because the 2017 BMW 750i uses multiple radial fitments and may have a staggered setup. After that, compare tire series, sidewall style, and any wheel-width guidance tied to the specific size you need.
A 245-width front tire and a 275-width rear tire serve different roles on this car, so the goal is preserving the intended size relationship rather than mixing similar-looking alternatives. It also helps to compare load figures where stated, along with the intended use of the car, whether that is daily road driving or occasional fair-weather use.
What sidewall styles are available for 2017 BMW 750i tires?
Sidewall styling for the 2017 BMW 750i includes blackwall, raised white letter, and redline, depending on tire size and series. Blackwall choices appear across several BFGoodrich and Nitto sizes, while Pro-Trac Street Pro III options bring raised white letter and redline styling in select 18- and 20-inch fitments.
The practical question is whether appearance or a more understated modern look matters more on the car. A blackwall keeps the presentation contemporary and restrained, while raised white letter or redline creates a much stronger visual statement, so the sidewall should be chosen only after the exact tire size is confirmed.
What brands offer tires for the 2017 BMW 750i?
Tires for the 2017 BMW 750i are available from BFGoodrich, Nitto, and Pro-Trac in the sizes covered here. Depending on the exact fitment, the selection includes g-Force series tires, Nitto NT555 G2, and Pro-Trac Street Pro III options.
Brand choice should come after the fitment basics are settled, since not every brand appears in every size. Once the right size is confirmed, comparing the available brands by sidewall presentation, tire series character, and rim-width compatibility where stated will usually narrow the field more effectively than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2017 BMW 750i?
A period-style approach on a 2017 BMW 750i still begins with the correct modern radial size for the car’s actual wheel package. Once the fitment is right, the visual direction can shift between understated blackwall presentation and more expressive options such as redline or raised white letter in certain sizes.
Because this is a recent luxury-performance sedan rather than a mid-century restoration, appearance usually centers on taste more than strict originality. Owners who want a showroom-era look should compare the car’s current wheels and consult BMW-specific references or original sales material before choosing a sidewall treatment that changes the car’s visual character.
How does tire construction affect the appearance of a restored 2017 BMW 750i?
Construction is straightforward on the 2017 BMW 750i because the primary fitments covered here are all radial. That means the appearance difference is shaped less by bias-ply-versus-radial concerns and more by profile, width, and sidewall treatment within the correct radial size.
A blackwall radial keeps the car closer to the clean, contemporary look expected of a late-model BMW sedan, while redline or raised white letter options create a more customized presentation. The size itself still matters most, since changing profile or axle-specific fitment affects the car’s stance as much as the sidewall design does.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 BMW 750i?
Yes. Modifications such as aftermarket wheels, changes in wheel width, suspension lowering, or altered offsets can affect tire fitment on a 2017 BMW 750i even when the tire size looks close to stock. That matters especially on staggered 19-inch and 20-inch setups where front and rear sizing already differs.
Clearance at the fender, inner wheelhouse, and steering components should be checked whenever the car no longer uses its original wheel setup. A replacement tire may still be the correct nominal size, but wheel changes can alter how that size sits on the car and whether it has adequate space in motion.
What should I inspect before driving a 2017 BMW 750i on new tires?
Before driving a 2017 BMW 750i on new tires, inspect the wheel diameter, confirm the tire size matches the correct front or rear position, and check that inflation is appropriate for the tire and vehicle setup. It also makes sense to look over the wheels for damage and confirm valve stems are in good condition.
A short recheck after initial road use is worthwhile, especially on a staggered car where front and rear tires are easy to mix up during service. Tire pressure, visible sidewall condition, and any sign of rubbing or unusual wear should be watched closely during the first miles after installation.
What should I check before a longer drive in a 2017 BMW 750i?
Before a longer drive, the 2017 BMW 750i should have correct tire pressures, adequate tread condition, and no visible cracking, bulges, or cuts. The car should also be wearing the proper front and rear sizes for its wheel package, since a staggered setup depends on keeping each axle in the right fitment.
A longer highway trip is also a good reason to confirm there is no slow air loss and that the wheels are free of damage or vibration issues. On a car with 19-inch or 20-inch wheels, even small fitment mistakes tend to show up quickly, so a careful walkaround before departure is time well spent.
