The 2017 BMW 740e xDrive blends the long-wheelbase luxury and technology focus of the G12 7 Series with plug-in hybrid drivability, making it a very different ownership experience than an older collector sedan but still one where correct tire fitment matters. On this model, tire choice starts with two primary radial sizes, 245/50R18 and 245/45R19, so the first step is confirming which wheel diameter is actually on the car. From there, the decision moves to tread and appearance details such as Blackwall, raised white letter, or Redline styling, along with brand and tire-series differences. That makes wheel verification especially important on cars that may have been changed from their original 18- or 19-inch setup.
Which Tire Size Is Right for The 2017 BMW 740e xDrive
The 2017 BMW 740e xDrive uses two primary tire sizes, and both are radial constructions. The key difference is wheel diameter: one fitment is for an 18-inch rim and the other is for a 19-inch rim. Before choosing a tire, confirm which wheel size is on the car, especially if it has been fitted with different wheels than its original setup.
245/45R19 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R designates radial construction, and 19 is the wheel diameter in inches. On the 2017 BMW 740e xDrive, this size suits a 19-inch wheel and reflects a contemporary low-profile fitment. Available choices include BFGoodrich and Nitto options in Blackwall form, with tire series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size is the right starting point only after the car's 19-inch wheel setup has been confirmed.
245/50R18 is also a modern metric radial size, using the same 245-millimeter nominal width but pairing it with a 50-series profile on an 18-inch rim. For a 2017 BMW 740e xDrive equipped with 18-inch wheels, it represents the alternate primary fitment rather than a substitute for the 19-inch setup. Current choices center on the Pro-Trac Street Pro III series and introduce appearance options such as raised white letter or Redline sidewalls. This size makes sense when the car retains or has been fitted with 18-inch wheels and clearance is being evaluated around that wheel-and-tire package.
Fitment is straightforward here because the covered sub-model uses the same two primary radial tire sizes. The main question is not trim identification so much as confirming whether the car is on its 18-inch or 19-inch wheel package before selecting tires.

Tire Size & Fitment
What tire size fits a 2017 BMW 740e xDrive?
The 2017 BMW 740e xDrive uses two primary tire sizes: 245/45R19 and 245/50R18. Both are radial fitments, and the difference between them comes down to wheel diameter rather than a change from bias-ply to radial or an antique sizing format.
That means the correct choice depends first on the wheels actually installed on the car. A 19-inch wheel uses 245/45R19, while an 18-inch wheel uses 245/50R18. If the BMW has aftermarket wheels or a changed wheel package, confirm the rim diameter before choosing a tire, then compare the available brand, series, and sidewall options within that size.
What size rim does a 2017 BMW 740e xDrive use?
A 2017 BMW 740e xDrive uses either an 18-inch or 19-inch rim, depending on which primary tire size is on the car. The 245/50R18 fitment pairs with an 18-inch wheel, and the 245/45R19 fitment pairs with a 19-inch wheel.
Because both tire sizes are valid for this model, rim diameter is the first thing to verify before comparing products. It is also worth checking wheel width and overall wheel setup if the car has been changed from its original configuration. The tire size on the sidewall and the wheel diameter should agree before any replacement tire is selected.
Why does the 2017 BMW 740e xDrive have more than one tire size?
The 2017 BMW 740e xDrive has more than one tire size because it was fitted with two different wheel diameters: 18-inch and 19-inch. The two sizes, 245/50R18 and 245/45R19, keep a very similar overall tire diameter while matching different wheels.
For the owner, that means the choice is not between two interchangeable primary sizes on the same rim. It is a matter of matching the tire to the wheel that is already on the vehicle. A quick check of the sidewall markings, wheel size, and current setup will prevent choosing the right width and profile on the wrong rim diameter.
Choosing the Right Tire
What should I consider when choosing a 245/45R19 tire for a 2017 BMW 740e xDrive?
Start with the basics: 245/45R19 must match a 19-inch wheel, and the available choices for this BMW are radial tires. Within that size, there are differences in brand, tire series, Blackwall styling, and rim-width specifications, so the decision is more about selecting the right type of 245/45R19 than deciding whether the size itself fits.
BFGoodrich and Nitto both appear in this fitment, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. Compare the tire's intended character, wheel-width compatibility, and any load information shown for the product. It also helps to confirm that the car still has its 19-inch setup and that there are no clearance issues from suspension or wheel changes.
What sidewall styles are available for 2017 BMW 740e xDrive tires?
The available sidewall styles for the 2017 BMW 740e xDrive include Blackwall, raised white letter, and Redline, depending on tire size and product selection. Blackwall choices appear in the 245/45R19 fitment, while the 245/50R18 options include raised white letter and Redline versions of the same Pro-Trac series.
That makes sidewall appearance part of the selection process once the correct size has been confirmed. A buyer looking for a more understated modern presentation may gravitate toward Blackwall, while raised white letter or Redline can create a more customized visual effect. The key is to choose the sidewall treatment within the correct 18-inch or 19-inch fitment rather than treating appearance as a substitute for proper sizing.
What brands offer tires for the 2017 BMW 740e xDrive?
Tires for the 2017 BMW 740e xDrive are available from BFGoodrich, Nitto, and Pro-Trac across its two primary sizes. BFGoodrich and Nitto appear in the 245/45R19 fitment, while Pro-Trac appears in the 245/50R18 fitment through the Street Pro III series.
Brand choice should come after wheel diameter and tire size have been confirmed. Once the car's 18-inch or 19-inch setup is known, compare each brand's available series, sidewall presentation, and any rim-width or load details shown with the product. That approach keeps the focus on selecting a tire that matches the car's actual setup instead of starting with a brand and forcing the fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2017 BMW 740e xDrive?
A period-style approach on a 2017 BMW 740e xDrive starts with keeping the correct primary size for the wheel diameter already on the car, either 245/50R18 or 245/45R19. Since this is a modern luxury sedan rather than a vintage bias-ply application, the more relevant appearance decision is which radial product and sidewall treatment best suits the car's presentation.
Blackwall maintains a restrained, contemporary look, while raised white letter or Redline choices in the 18-inch fitment create a more customized appearance. Exact originality matters more on some collector vehicles than others, so owners pursuing a highly specific presentation should compare against marque references and the car's existing wheel package before making an appearance-driven tire change.
How does tire construction affect the appearance of a restored 2017 BMW 740e xDrive?
On a 2017 BMW 740e xDrive, construction is less about bias-ply versus radial and more about selecting the right radial tire within the correct size. Both primary fitments are radial, so the visual effect comes mainly from profile, wheel diameter, and sidewall style rather than from an old-versus-new construction decision.
That means a 19-inch Blackwall tire will present differently than an 18-inch tire with raised white letter or Redline styling, even though both are correct primary fitments for this model. For an owner interested in a restoration-oriented appearance, keeping the wheel diameter consistent with the intended setup and choosing a sidewall style thoughtfully will shape the finished look more than construction alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 BMW 740e xDrive?
Yes, modifications can affect tire fitment on a 2017 BMW 740e xDrive. Wheel changes, altered wheel width, suspension modifications, or a different ride height can all change how a 245/50R18 or 245/45R19 tire sits in the wheel opening and how much steering and suspension clearance remains.
That is especially important on a car with two valid factory-style wheel diameters, because an owner may assume any listed size will work with any setup. It helps to verify wheel diameter, width, and the actual tire size already on the car, then inspect for clearance at full steering lock and through suspension movement before committing to a replacement.
What should I inspect before driving a 2017 BMW 740e xDrive on new tires?
Before driving a 2017 BMW 740e xDrive on new tires, confirm that the tire size matches the wheel diameter, check inflation pressure, and inspect the wheels for damage or irregular seating. It is also smart to make sure all four tires are the intended size and that the sidewalls and tread area are free from shipping or installation damage.
A short inspection after installation can prevent larger problems later. Look for rubbing at the fenders or suspension, especially if the BMW has nonstandard wheels, and pay attention to any vibration or pull on the first drive. Rechecking pressure and verifying that the tire size on the car matches either the 18-inch or 19-inch setup helps keep the fitment sorted.
What should I check before a longer drive in a 2017 BMW 740e xDrive?
Before a longer drive in a 2017 BMW 740e xDrive, inspect tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. Since this model uses either 245/50R18 or 245/45R19, it is also worth confirming that the tires match the wheel diameter on the car and that there is no sign of rubbing or uneven wear.
Longer trips place more emphasis on small issues that may not show up around town. A quick look at air loss, wheel condition, and general tread wear can reveal problems early. If the BMW has spent time parked or is driven infrequently, extra attention to tire age and condition is worthwhile before putting sustained highway miles on the vehicle.
