BMW 740e xDrive Tires

BMW 740e xDrive uses three tire sizes across the 2017 to 2019 model years: 245/50R18, 245/45R19, and 275/40R19. The 245/50R18 size appears in 2017, 2018, and 2019 with an 18-inch rim diameter. The 245/45R19 size also appears in 2017, 2018, and 2019 with a 19-inch rim diameter. The wider 275/40R19 size is used in 2018 and 2019 and also requires a 19-inch rim.

That means year alone is not enough to choose correctly, especially on 2018 and 2019 cars. Start by reading the size on the tires currently fitted, then confirm the wheel diameter and whether the car uses the narrower 245-section setup or the wider 275-section 19-inch application. If the car has changed wheels at some point, the mounted tire size and wheel measurement matter more than assumptions about model year.

A 2018 BMW 740e xDrive has three listed sizes because that model year includes both an 18-inch fitment and two different 19-inch fitments. The sizes are 245/50R18, 245/45R19, and 275/40R19. That is a wheel-and-configuration split rather than a single universal tire size. The same pattern continues into 2019, while 2017 shows only the 245/50R18 and 245/45R19 sizes.

The practical takeaway is to identify the specific wheel setup on the car before choosing a replacement. A buyer should confirm whether the car sits on 18-inch wheels or 19-inch wheels, and then verify whether the 19-inch setup uses the narrower 245-section size or the wider 275-section size. Looking at the sidewall marking on the existing tire is usually the quickest first step, followed by checking the actual wheel diameter.

BMW 740e xDrive uses two rim diameters in this model group: 18 inches and 19 inches. The 245/50R18 size is built for 18-inch wheels, while both 245/45R19 and 275/40R19 are built for 19-inch wheels. Both diameters appear within the 2017 to 2019 production span, so there is no single wheel size that covers every car in the group.

That makes wheel diameter the first physical check before anything else. A tire marked for an 18-inch rim cannot be mounted on a 19-inch wheel, and the reverse is equally true. On a BMW 740e xDrive that may have changed hands or received aftermarket wheels, measure or read the wheel and tire markings rather than relying only on memory or a general year-based assumption.

A 2017 BMW 740e xDrive uses either 245/50R18 or 245/45R19, so the correct choice depends on which wheels are actually on the car. The 18-inch option takes 245/50R18, while the 19-inch option takes 245/45R19. There is no 275/40R19 listing for 2017 in this model group, so that later wider 19-inch size belongs to 2018 and 2019 applications instead.

The cleanest way to verify a 2017 BMW 740e xDrive is to read the existing sidewall size and confirm the wheel diameter at the same time. If the car has been modified, compare what is mounted now against the intended wheel setup rather than assuming the car still wears its original configuration. Matching the exact size already fitted is usually the safest starting point unless a knowledgeable BMW specialist has specified a different approved setup.

BMW 740e xDrive tires in these listings are available in Blackwall, RWL, and Redline sidewall styles. The 19-inch sizes shown here are Blackwall, while the 245/50R18 options are offered in both RWL and Redline variations within the same Pro-Trac Street Pro III series. That means the sidewall appearance can vary even when the numeric size is the same.

For most BMW 740e xDrive owners seeking a factory-like modern appearance, Blackwall is the closest visual match to the car's original luxury-sedan character. RWL and Redline options give the 18-inch size a more customized look and may appeal to owners pursuing a period-inspired custom style rather than an OEM-style presentation. Sidewall style does not replace the need to match the correct size and wheel diameter first.

BMW 740e xDrive tires in this selection come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both 245/45R19 and 275/40R19 sizes, Nitto also appears in both 19-inch sizes, and Pro-Trac covers the 245/50R18 size. That gives the model group three distinct brands spread across the available 18-inch and 19-inch applications.

Brand choice should come after fitment is settled, not before. Once the correct size is confirmed, buyers can compare the available brand options in that exact size and consider whether they want a conventional Blackwall appearance or, in the 18-inch size, a more distinctive RWL or Redline sidewall. Keeping the comparison within the exact required size avoids accidentally choosing a tire that looks right but does not fit the wheel.

BMW 740e xDrive tire options here include g-Force Comp 2 AS, Nitto NT555 G2, g-Force Phenom T/A, Street Pro III, and g-Force Sport Comp 2. All are radial tires, but they are offered across different sizes and sidewall presentations. Street Pro III appears in the 245/50R18 size with RWL and Redline versions, while the BFGoodrich and Nitto series cover the 19-inch sizes in Blackwall form.

That means the series choice is partly a fitment question and partly a style question. A BMW 740e xDrive owner with 18-inch wheels is looking at a different series family than someone with 19-inch wheels, and a 2018 or 2019 owner may also need to distinguish between the narrower 245-section and wider 275-section 19-inch applications. Once size is locked in, comparing series helps narrow the right visual and performance character for the car.

A BMW 740e xDrive stored with its tires fitted should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, and ozone-producing equipment. Clean tires and proper inflation matter because low-profile radial tires can develop stress from long periods of underinflation or standing weight. If the car will sit for an extended time, moving it periodically helps avoid flat spotting.

Collector-minded owners often treat a stored luxury sedan gently, but tires still age even when mileage stays low. Keeping the BMW 740e xDrive off hot pavement and away from chemical exposure will help preserve both the rubber and the sidewall appearance. If storage lasts months at a time, check inflation regularly so the car is not resting on partially deflated tires that can distort over time.

Tires on a BMW 740e xDrive should be inspected regularly even if the car is driven only occasionally. A visual inspection before each outing is wise on a low-use vehicle, and a more thorough check at routine service intervals should include tread wear, sidewall cracking, impact damage, and inflation condition. Because this model group uses low-profile radial sizes, curb damage and uneven shoulder wear deserve close attention.

Inspection is especially important when the car has multiple possible fitments, because mismatched sizes or uneven wear can hint at a wheel or setup issue. Check that the front and rear sizes match the intended configuration and that all four tires carry the expected size markings for the wheel package on the car. Catching a problem early is easier than discovering vibration, poor handling, or clearance trouble after a long period of storage.

A BMW 740e xDrive can need tire replacement even when tread depth still looks serviceable. Age-related hardening, sidewall cracking, impact damage, irregular wear, vibration, or signs of internal deterioration are all valid reasons to retire a tire before the tread is gone. That is particularly relevant on collector-kept modern luxury cars that may accumulate time faster than mileage.

Owners should think of tires on a BMW 740e xDrive as aging components, not just wear components. If the car has spent long periods parked, a specialist tire inspection is worthwhile before resuming regular driving, especially on low-profile 18-inch or 19-inch fitments that place more demand on the sidewall structure. Replacing an aged set as a complete matched group often preserves the car's ride quality and consistency better than replacing one tire at a time.

These BMW 740e xDrive tire options are modern radial tires intended for road use in the sizes listed, but road safety depends on correct fitment, proper condition, and matching the tire to the wheel actually on the car. The key details here are the exact size and the wheel diameter, since the model group includes both 18-inch and 19-inch applications. A tire that is the wrong size for the wheel or axle configuration is not a safe substitute.

Before road use, make sure the BMW 740e xDrive has a complete, matching set appropriate to its configuration and that each tire is free of age cracking, impact damage, or abnormal wear. Cars that are driven infrequently should also have tire pressures checked before every outing. Safe road use starts with confirming fitment first and condition second, rather than assuming any tire from the same model range will work interchangeably.

Before driving a BMW 740e xDrive, check tire pressure, visible condition, and the size markings on the tires if there is any question about the car's wheel setup. A 245/50R18 belongs on an 18-inch wheel, while 245/45R19 and 275/40R19 belong on 19-inch wheels. Also look for cuts, bubbles, sidewall abrasions, and uneven tread wear that could point to damage or alignment issues.

That quick inspection matters because this model group can appear with more than one legitimate fitment, especially in 2018 and 2019. If the car was recently acquired, stored for a long period, or fitted with aftermarket wheels, checking the mounted size can prevent a costly mistake and improve confidence on the road. A short pre-drive walkaround is often enough to catch a problem before it affects ride, handling, or tire durability.

A BMW 740e xDrive should only be driven at speeds appropriate to the exact tire fitted, its condition, and the overall condition of the car. The listed products include modern radial constructions in ZR-marked sizes, but the practical road speed should still reflect inflation, age, wear, and whether all four tires are correctly matched. Tire capability on paper does not override the realities of a heavy luxury sedan and an aging collector-car maintenance cycle.

Owners should treat a newly acquired or long-stored BMW 740e xDrive conservatively until the tires and chassis have been fully inspected. Smooth, moderate-speed driving is the sensible approach until you know the car is wearing the correct size and the tires are healthy. If there is any vibration, pull, noise, or visible aging, address that first rather than assuming the tire's nominal performance category makes higher-speed use appropriate.
