BMW 745e xDrive Tires

BMW 745e xDrive uses three listed tire sizes across the 2020 through 2022 model years: 245/50R18, 245/45R19, and 275/40R19. The 245/50R18 size fits 18-inch wheels, while both 245/45R19 and 275/40R19 fit 19-inch wheels. All three sizes appear in each of the three years, so year alone does not narrow the fitment to a single answer.

The practical takeaway is that you need to check the actual wheel and tire package on the car before replacing anything. Start with the size molded into the sidewall, then confirm whether the BMW 745e xDrive has the same size at all four corners or uses a wider rear tire with a different front size.

A 2020 BMW 745e xDrive has three tire sizes listed because that year includes more than one wheel-and-tire configuration. The split is tied to rim diameter, with both 18-inch and 19-inch fitments appearing, and the 19-inch setup also includes a wider size in the range. The same pattern continues for 2021 and 2022 models.

That means the correct tire depends on the exact configuration of your car, not simply the model year. Check the wheel diameter first, then compare the front and rear sidewalls to see whether the car uses matching tires at all four corners or a staggered arrangement with a wider rear fitment.

BMW 745e xDrive appears with two rim diameters in this fitment group: 18 inches and 19 inches. The 245/50R18 size is for 18-inch wheels, while both 245/45R19 and 275/40R19 are for 19-inch wheels. Those diameters are present across the full 2020 to 2022 span rather than being tied to an early-versus-late production change.

The most important step is to verify the wheel diameter on the actual car before choosing a tire. If you are replacing only two tires, also make sure you are matching the correct axle, because an 18-inch fitment cannot be substituted onto a 19-inch wheel and the two 19-inch sizes may serve different positions.

A 2021 BMW 745e xDrive can use 245/50R18, 245/45R19, or 275/40R19, so the correct choice comes from the car's actual wheel-and-tire package rather than the year alone. The sidewall on each tire will show the installed size, and the wheel diameter must match exactly. If the car uses 19-inch wheels, the wider 275/40R19 may be paired with a narrower 245/45R19 depending on axle position.

Begin by reading all four tires and noting whether the front and rear sizes are the same or different. That check matters on BMW 745e xDrive because replacing a single pair without confirming the existing layout can upset the intended balance of ride, handling, and overall appearance.

BMW 745e xDrive tire options in this group include Blackwall, RWL, and Redline sidewall styles. Blackwall appears on the 19-inch BFGoodrich and Nitto options, while the 18-inch Pro-Trac 245/50R18 products are offered in both RWL and Redline versions. All listed products are radial designs.

Most buyers seeking a modern luxury-sedan look will likely stay with blackwall styling, especially on the 19-inch sizes. The RWL and redline choices offer a more custom visual treatment, so they make the most sense when the goal is a particular appearance rather than a strictly factory-like sidewall presentation.

BMW 745e xDrive tire options here come from three brands: BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both 245/45R19 and 275/40R19 sizes, Nitto is also offered in those two 19-inch sizes, and Pro-Trac covers the 245/50R18 fitment. That spread gives the model a mix of touring and performance-oriented radial choices depending on size.

Brand matters less than matching the exact installed size, rim diameter, and intended axle position. Once fitment is confirmed, compare sidewall style, tire series, and any load or wheel-width details that matter to how your BMW 745e xDrive is equipped and how you plan to use it.

BMW 745e xDrive tire series in this group include g-Force Comp 2 AS, Nitto NT555 G2, g-Force Phenom T/A, Street Pro III, and g-Force Sport Comp 2. All of them are radial tires, but they differ by brand family, size coverage, and sidewall presentation. Street Pro III is the 18-inch option here, while the g-Force and Nitto series cover the listed 19-inch sizes.

The useful way to compare them is to start with fitment, then narrow by the appearance and driving character you want from the car. On BMW 745e xDrive, the first decision is always 18-inch versus 19-inch wheel fitment, because choosing the wrong rim diameter removes every other series comparison from consideration.

A BMW 745e xDrive should be stored on a clean, dry surface away from direct sunlight, electric motors, welders, and ozone-producing equipment that can age rubber more quickly. Keep the tires inflated to an appropriate pressure for storage and avoid leaving the car parked for long periods with excessive load concentrated in one spot. Clean tires and wheels before storage so contaminants do not sit against the rubber.

If the car will sit for weeks or months, move it periodically or use methods that reduce flat-spotting and long-term carcass stress. That matters on BMW 745e xDrive because its weight can be harder on tires during inactivity than on a lighter collector car or weekend cruiser.

Tires on a BMW 745e xDrive should be inspected regularly even if the car is driven only occasionally. Check pressure, tread wear pattern, sidewall condition, punctures, cracking, and any signs of impact damage from potholes or curb contact. A heavier luxury-performance sedan can hide tire problems until they become obvious in ride quality or handling.

A good routine is to inspect the tires before any longer drive and any time the car has been stored for an extended period. On a BMW 745e xDrive with mixed front and rear sizing, inspect all four tires individually rather than assuming the rear pair and front pair will wear or age at the same rate.

Tires on a BMW 745e xDrive should be replaced when age, cracking, impact damage, irregular wear, or internal deterioration make them questionable, even if visible tread remains. Collector and low-use cars often age out their tires before they wear them out. Any vibration, bulging, severe weather checking, or repeated air loss deserves immediate evaluation.

Age-related replacement is especially important on a heavy, high-speed-capable sedan because old rubber can lose grip and structural confidence long before the tread appears used up. If the service history is unclear, treat the tire's age and overall condition as seriously as its remaining tread depth.

BMW 745e xDrive appears here with three fitment sizes used across 2020 to 2022: 245/50R18, 245/45R19, and 275/40R19. The available replacement products are all radial tires, with blackwall, RWL, and redline sidewall options depending on size. More than one wheel-and-tire package was used within the model group, so there is no single one-size answer for every BMW 745e xDrive.

For originality, the best approach is to confirm the exact wheel package your specific car left the factory with and then match size and appearance accordingly. The sidewall style matters less on a modern luxury BMW than exact fitment, but it still influences how authentic or customized the finished car looks.

Correct tire fitment does affect how a BMW 745e xDrive presents, especially when wheel size, stance, and sidewall appearance are part of the car's intended design. Using the wrong overall size or mismatching front and rear fitment can alter the visual balance and may also suggest that the car has been maintained without close attention to specification.

For an enthusiast-owned or carefully preserved BMW 745e xDrive, accuracy starts with the proper wheel diameter and the correct size on each axle. If the car is being kept to a high originality standard, retain the tire format and sidewall style that best align with the car's original wheel-and-tire package rather than choosing by appearance alone.

BMW 745e xDrive options in this group include Blackwall, RWL, and Redline sidewall styles. Blackwall is available on the listed 19-inch BFGoodrich and Nitto tires, while the 18-inch Pro-Trac size offers RWL and Redline alternatives. Since BMW 745e xDrive is a modern luxury-performance sedan, blackwall will generally read as the most restrained and factory-like look.

If the goal is a restoration-minded presentation, begin with the sidewall style that matches the car's original visual character and wheel package. RWL and redline treatments are better suited to an owner who wants a deliberate custom touch, while blackwall is the safer choice for preserving the understated appearance expected of a 7 Series.

The listed BMW 745e xDrive tire options are modern radial tires intended for road use when they are the correct size for the wheel, are in sound condition, and are installed as a proper matched set for the car's configuration. Safety depends on exact fitment, condition, inflation, and load suitability as much as on the brand name or tread design.

Before regular road use, make sure the BMW 745e xDrive is wearing the correct 18-inch or 19-inch tire size and that any staggered arrangement is preserved correctly. A tire that is sound but wrong for the wheel or axle position is not an acceptable substitute on a heavy luxury-performance sedan.

Before driving a BMW 745e xDrive, inspect tire pressure, visible tire condition, tread depth, and any signs of cuts, bulges, or impact damage. Confirm that the sizes on the car match the wheel diameters and that left and right tires on the same axle are the same size and comparable in condition. Also look for uneven wear that may point to alignment or suspension issues.

That inspection is especially worthwhile if the car has sat for a while or if you recently acquired it. On BMW 745e xDrive, a quick sidewall check can also reveal whether the car carries a square setup or a wider rear tire arrangement, which matters before rotating, replacing, or pairing tires.

A BMW 745e xDrive should only be driven at speeds appropriate to the exact tire installed, its condition, and the overall mechanical state of the car. The listed replacement tires are modern radial designs, but safe speed is never just a matter of the number on the sidewall. Tire age, inflation, load, and whether the fitment matches the intended axle all play into the answer.

For practical use, drive the BMW 745e xDrive conservatively until you know the tires are properly sized, evenly worn, and correctly inflated. Any uncertainty about age, hidden damage, or mixed fitment is a reason to limit speed and resolve those issues before asking the car to perform like a high-speed luxury sedan.
