The 2020 BMW 740i xDrive sits in BMW’s modern flagship luxury-sedan tradition, blending long-wheelbase comfort, high-speed composure, and all-wheel-drive confidence in a package that still rewards careful chassis tuning. Tire selection matters here because this car can appear with multiple factory-size combinations, including 18-, 19-, and 20-inch radial fitments, and some setups use a staggered front-and-rear arrangement. That means the real decision is not simply finding a tire, but matching the exact wheel setup already on the car. Available choices also vary by brand, sidewall style, and tire series, so appearance and driving intent can both influence the final selection.
Which Tire Size Is Right for The 2020 BMW 740i xDrive
The 2020 BMW 740i xDrive uses five primary tire sizes, and the right one depends on the exact wheel package fitted to the car. Because these fitments span 18-inch, 19-inch, and 20-inch rims and may be part of a staggered front-and-rear setup, the first step is confirming wheel diameter and whether the car uses the same size at all four corners or different front and rear tires.
245/45R19 is a modern metric radial size: 245 indicates nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2020 BMW 740i xDrive, this size serves as a front or all-around fitment depending on the wheel setup already on the car. Available choices center on blackwall performance-oriented tires from BFGoodrich and Nitto across the g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. It is a useful size to confirm carefully when the car has 19-inch wheels and may be paired with a wider rear tire.
245/50R18 is a metric radial size with a 245-millimeter nominal section width, a 50-series profile, radial construction, and an 18-inch rim diameter. For the 2020 BMW 740i xDrive, this is one of the square-fitment sizes, so the same size can be used at all four corners when the car is equipped with the matching wheel package. Product choice here leans toward Pro-Trac Street Pro III options with raised white letter or redline sidewall treatments rather than a purely blackwall presentation. This size is worth considering when the car has 18-inch wheels and the owner wants to balance fitment accuracy with a distinctive sidewall look.
245/40R20 uses the same 245-millimeter nominal width but a lower 40-series profile on a 20-inch rim, which gives it a noticeably different sizing context from the 18- and 19-inch options. On the 2020 BMW 740i xDrive, this size functions as a front fitment when the car is equipped with the 20-inch staggered setup. Selection includes blackwall choices from BFGoodrich and Nitto as well as Pro-Trac Street Pro III in raised white letter and redline versions. It should be chosen only after confirming that the car has the corresponding 20-inch front wheels and the matching wider rear size.
275/35R20 is a wider modern metric radial size, with 275 showing nominal section width in millimeters, 35 indicating a lower-profile sidewall, R for radial construction, and 20 for the rim diameter. For the 2020 BMW 740i xDrive, this size is used at the rear in the 20-inch staggered arrangement rather than as a universal four-corner fitment. Buyers will find blackwall options from BFGoodrich and Nitto alongside Pro-Trac Street Pro III offerings in raised white letter and redline styles. This is the size to evaluate when the rear wheels are 20-inch and wider than the fronts.
275/40R19 combines a 275-millimeter nominal section width with a 40-series profile on a 19-inch rim, making it the wider rear companion to the 245/45R19 front size in a staggered 19-inch arrangement. On the 2020 BMW 740i xDrive, it belongs to the rear position on that setup rather than to every configuration. Available options are concentrated in blackwall form, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and Nitto NT555 G2. This size should be selected only after confirming that the car uses 19-inch staggered wheels and not the square 18-inch package.
Sub-model naming on the 2020 BMW 740i xDrive mainly reflects whether the tire position is all-around, front, or rear. Checking the exact sub-model matters because some configurations use the same size at all four corners, while others use a staggered setup with different front and rear tires.

2020 BMW 740i xDrive Base
The 2020 BMW 740i xDrive Base uses a square fitment, with one of its applicable sizes mounted at all four corners depending on whether the car has 18-inch or 19-inch wheels. Tire selection starts with wheel diameter confirmation, then moves to choosing among the available radial products and sidewall treatments in that size.
The 2020 BMW 740i xDrive Base Front sub-model represents the front axle in a staggered arrangement, using either a 19-inch or 20-inch front tire size. That makes front-wheel diameter especially important, since the correct choice must also match the rear tire setup already on the car.
The 2020 BMW 740i xDrive Base Rear sub-model covers the wider rear tire used with staggered 19-inch or 20-inch wheel packages. Tire choice here should focus on matching the existing rear wheel diameter and preserving the intended front-to-rear pairing rather than selecting by width alone.
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 2020 BMW 740i xDrive usually need to sort out wheel diameter, square versus staggered fitment, and the available radial tire choices before comparing brands or sidewall styles. These FAQs focus on those exact fitment and selection questions.
Tire Size & Fitment
What tire size fits a 2020 BMW 740i xDrive?
The 2020 BMW 740i xDrive uses five primary tire sizes: 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20. All of them are radial sizes, but they do not all apply to the same wheel package or axle position.
The key is confirming whether the car has a square setup with the same size at all four corners or a staggered setup with narrower front tires and wider rear tires. Checking the wheel diameter on the car first prevents choosing the right width in the wrong rim size.
What size rim does a 2020 BMW 740i xDrive use?
The 2020 BMW 740i xDrive uses 18-inch, 19-inch, or 20-inch rims depending on the tire size and wheel package. The 245/50R18 fits an 18-inch rim, 245/45R19 and 275/40R19 fit 19-inch rims, and 245/40R20 with 275/35R20 fit 20-inch rims.
Wheel diameter should be verified before anything else because this car spans three different rim sizes. A width match alone is not enough, and on staggered cars the front and rear rim diameters must also remain paired with the correct companion tire sizes.
Why does the 2020 BMW 740i xDrive have more than one tire size?
More than one tire size appears on the 2020 BMW 740i xDrive because the car can be equipped with different wheel packages, including square fitments and staggered front-and-rear combinations. That is why narrower 245-section sizes and wider 275-section sizes both appear for this model.
The practical takeaway is that the correct tire is tied to the exact wheels already installed on the car, not just the model name. Looking at the existing tire sidewall and confirming whether the front and rear sizes match will usually answer the fitment question quickly.
Choosing the Right Tire
What should I consider when choosing a 2020 BMW 740i xDrive tire?
Start with the exact size already used on the car, then confirm whether the setup is square or staggered. On a 2020 BMW 740i xDrive, that means matching the correct 18-, 19-, or 20-inch fitment and making sure front and rear sizes stay properly paired when the car uses different widths.
After fitment is settled, compare the available radial choices by tire series, sidewall style, and wheel compatibility. Some sizes are offered only in blackwall form, while others include raised white letter or redline treatments, so the final choice can reflect both the car’s setup and the owner’s preferred appearance.
What sidewall styles are available for 2020 BMW 740i xDrive tires?
Sidewall style depends on the tire size chosen for the 2020 BMW 740i xDrive. Blackwall options are available in the 19-inch and 20-inch performance-oriented sizes, while certain Pro-Trac sizes are also offered with raised white letter and redline sidewalls.
That matters because appearance choices are not spread evenly across every fitment. A buyer selecting an 18-inch or 20-inch Pro-Trac option may have more visual variety, while shoppers focused on 19-inch staggered sizes will mainly be comparing blackwall tires across different radial series and brand families.
What brands offer tires for the 2020 BMW 740i xDrive?
Tires for the 2020 BMW 740i xDrive are available from BFGoodrich, Nitto, and Pro-Trac. Brand availability varies by size, with BFGoodrich and Nitto concentrated in blackwall 19-inch and 20-inch fitments, while Pro-Trac appears in selected sizes with more sidewall-style variety.
The useful comparison is not simply brand name, but how each brand overlaps with the size already on the car. Once the wheel package is confirmed, the next step is comparing the available series, sidewall presentation, and any rim-width guidance that applies to that specific tire size.
Restoration & Appearance
Which tire should I choose for a period-style 2020 BMW 740i xDrive?
A period-style choice for a 2020 BMW 740i xDrive usually starts with keeping the exact wheel-package size already fitted to the car. Since this is a modern luxury sedan with radial-only fitments, the visual decision tends to revolve more around sidewall presentation and tire series than around vintage construction choices.
Pro-Trac options in certain 18-inch and 20-inch sizes introduce raised white letter or redline styling, while many BFGoodrich and Nitto choices keep a cleaner blackwall look. The better match depends on whether the goal is a restrained modern appearance or a more customized enthusiast presentation.
How does tire construction affect the appearance of a restored 2020 BMW 740i xDrive?
Tire construction is straightforward on the 2020 BMW 740i xDrive because every primary fitment here is radial. That means appearance differences come less from bias-ply versus radial shape and more from the actual size, profile, and sidewall treatment selected for the existing wheel package.
A blackwall tire keeps the look closer to what most buyers expect on a modern BMW sedan, while raised white letter or redline options push the car toward a more personalized visual style. Keeping the correct front-to-rear size relationship is also important, since staggered proportions influence the car’s stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 BMW 740i xDrive?
Yes. Wheel changes, suspension lowering, spacers, or any shift away from the original 18-, 19-, or 20-inch package can affect tire fitment on a 2020 BMW 740i xDrive. That becomes even more important on staggered setups, where the front and rear sizes are intentionally different.
A modified car should be checked for wheel diameter, wheel width, and clearance at steering lock and through suspension travel before a new tire is chosen. Even when a tire size looks close on paper, the real-world fit depends on the exact wheel and body setup already in place.
What should I inspect before driving a 2020 BMW 740i xDrive on new tires?
Before road use, inspect inflation pressure, wheel condition, lug torque, and the tire sidewall markings to confirm the correct sizes are mounted in the correct positions. On a 2020 BMW 740i xDrive with staggered fitment, the front and rear tires should also be checked to make sure they were not accidentally reversed.
A quick clearance check is worthwhile after installation, especially on cars with 20-inch wheels or any suspension changes. It also helps to watch for vibration, unusual rubbing, or uneven wear during the first few drives so any mounting or alignment issue can be corrected early.
What should I check before a longer drive in a 2020 BMW 740i xDrive?
Before a longer drive, confirm that all four tires are at the proper pressure, inspect the tread and sidewalls for cuts or bulges, and make sure the sizes on the car match the intended wheel setup. On a 2020 BMW 740i xDrive, that includes verifying the correct front and rear pairing on staggered applications.
Longer trips are also a good time to check for slow air loss, vibration, or uneven wear that may point to alignment or wheel issues. Collector cars are not the focus here, but any low-use vehicle still benefits from regular inspection because age and storage can affect tire condition.
