The 2019 BMW 740i sits in the modern luxury-sedan category where ride quality, high-speed composure, and crisp steering all depend heavily on getting the tire setup right. As part of BMW’s flagship 7 Series lineup, it blends long-wheelbase comfort with a distinctly performance-minded chassis, which is why tire fitment can vary by wheel package and front-to-rear application. This model uses radial tire sizes across 18-inch, 19-inch, and 20-inch rims, with both square and staggered setups represented. Available choices include blackwall, raised white letter, and redline sidewall treatments across several performance-oriented series. The key is confirming the exact wheel and axle setup before choosing tires for appearance, handling character, or replacement fitment.
Which Tire Size Is Right for The 2019 BMW 740i
The 2019 BMW 740i uses five primary tire sizes, and the correct one depends on the exact wheel package and whether the car has a square or staggered setup. Rim diameter is the first thing to confirm, since this model appears with 18-inch, 19-inch, and 20-inch wheels, and the front and rear sizes can differ on staggered applications. Once that is settled, the real decision becomes choosing the right radial tire series, sidewall style, and product specifications within the correct size.
245/45R19 is a metric radial size where 245 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2019 BMW 740i, this size suits a 19-inch wheel application and appears in a modern radial format appropriate for the car’s luxury-performance character. Available choices include BFGoodrich and Nitto in blackwall form, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size is worth confirming carefully when the car is not running the staggered front-and-rear 20-inch setup.
245/50R18 is a metric radial size that uses a 245-millimeter nominal section width, a 50-series profile, and an 18-inch rim. For the 2019 BMW 740i, it represents the 18-inch square fitment choice and keeps the tire in a radial construction suited to modern road use. Product selection in this size includes Pro-Trac Street Pro III options with raised white letter and redline sidewall treatments, giving the buyer a stronger appearance choice than some of the other sizes. This size should be matched to the actual 18-inch wheel setup before comparing styling or performance-oriented product differences.
245/40R20 is a metric radial size with a 245-millimeter section width, a lower 40-series profile, and a 20-inch rim diameter. On the 2019 BMW 740i, this size serves the front position in the staggered 20-inch arrangement, pairing a shorter sidewall look with the model’s larger wheel package. Available products span BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall styles depending on the tire series. This is the size to evaluate when the front axle carries 20-inch wheels and appearance or series selection matters as much as basic fitment.
275/35R20 is a metric radial size that combines a wider 275-millimeter section width with a 35-series profile on a 20-inch rim. For the 2019 BMW 740i, it is the rear tire size used with the staggered 20-inch setup, making it a different fitment role than the narrower front tire. Choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall options alongside raised white letter and redline treatments in the Street Pro III line. This size should be selected only after confirming the car uses the staggered rear 20-inch wheel package rather than a square configuration.
275/40R19 is a metric radial size with a 275-millimeter section width, a 40-series aspect ratio, and a 19-inch rim diameter. On the 2019 BMW 740i, this size is used at the rear in the staggered 19-inch arrangement, so it works as the wider companion to the front 245/45R19 tire rather than as a universal fitment. BFGoodrich and Nitto offerings appear in this size, primarily in blackwall form, across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. It is the right size to examine when rear-wheel fitment differs from the front on a 19-inch package.
Sub-model fitment on the 2019 BMW 740i is tied closely to wheel package and axle position rather than trim hierarchy alone. Checking whether the car is using the base square setup or the staggered front and rear arrangement is the most important step before selecting tires.

2019 BMW 740i Base
The 2019 BMW 740i Base uses a square fitment with either an 18-inch or 19-inch tire size depending on the wheel setup. That makes wheel diameter the first checkpoint, followed by sidewall style and tire-series preferences within the correct radial size.
The 2019 BMW 740i Base Front uses the narrower front tire sizes in the staggered arrangements, with either 19-inch or 20-inch front-wheel fitment. Tire selection here should focus on confirming the front wheel diameter and matching the front axle size correctly before comparing brands or sidewall treatments.
The 2019 BMW 740i Base Rear uses the wider rear tire sizes that complete the staggered setups on 19-inch or 20-inch wheels. That means rear tire choice should be made with special attention to wheel diameter and axle position so the wider rear fitment stays properly matched to the car’s layout.
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.
Best 2019 BMW 740i Tires for Sale
Available 2019 BMW 740i tire options span BFGoodrich, Nitto, and Pro-Trac across several radial performance series. Depending on size, buyers can compare blackwall, raised white letter, and redline styles along with meaningful differences in rim-width compatibility, load figures, and tire weight.
Owners of a 2019 BMW 740i usually need to sort out wheel diameter, square versus staggered fitment, and the difference between front and rear sizes before choosing tires. The questions below focus on exact size fitment, available tire styles, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2019 BMW 740i?
The 2019 BMW 740i uses several radial tire sizes: 245/50R18, 245/45R19, 245/40R20, 275/40R19, and 275/35R20. Some setups are square, using the same size across an axle pair, while others are staggered, with a narrower front tire and a wider rear tire.
The right choice depends on the exact wheel package and whether the car has matching front and rear sizes or a staggered arrangement. Start by checking the wheel diameter at the car, then confirm whether the tire being replaced is on the front or rear axle before comparing brands, sidewall styles, or tire series.
What size rim does a 2019 BMW 740i use?
A 2019 BMW 740i appears with 18-inch, 19-inch, and 20-inch rim diameters depending on the tire size and setup. The 245/50R18 size uses an 18-inch rim, the 245/45R19 and 275/40R19 sizes use 19-inch rims, and the 245/40R20 and 275/35R20 sizes use 20-inch rims.
Rim diameter should be confirmed before anything else because it separates every primary fitment used on this model. The next check is whether the car is running a square setup or staggered front and rear tires, since the axle position matters just as much as the wheel diameter on the 19-inch and 20-inch packages.
Why does the 2019 BMW 740i have more than one tire size?
The 2019 BMW 740i has more than one tire size because it was fitted with different wheel diameters and both square and staggered tire arrangements. Square fitments use the same size at all four corners, while staggered setups use a narrower front size and a wider rear size.
That means two cars with the same year, make, and model may not use the same tire package. A quick look at the existing tire sidewall, wheel diameter, and axle position usually answers the question faster than choosing by model name alone, especially when comparing 19-inch and 20-inch applications.
Choosing the Right Tire
What should I consider when choosing a 2019 BMW 740i tire?
Start with the exact size already on the car, then confirm whether the 2019 BMW 740i uses an 18-inch, 19-inch, or 20-inch wheel package and whether the setup is square or staggered. Every primary fitment on this model is radial, so the main comparison points become the correct size, axle position, tire series, and wheel compatibility.
After size is settled, compare the product details that affect how the tire suits the car and your priorities. Sidewall style, rim-width specification, load figure when stated, and overall tire character all matter, especially on a luxury-performance sedan where ride, appearance, and front-to-rear balance should stay in sync.
What sidewall styles are available for 2019 BMW 740i tires?
Sidewall choices for the 2019 BMW 740i include blackwall, raised white letter, and redline, depending on the tire size and series. Blackwall options appear broadly across BFGoodrich and Nitto products, while raised white letter and redline treatments show up in Pro-Trac Street Pro III sizes such as 245/50R18, 245/40R20, and 275/35R20.
The sidewall decision is mostly about presentation once the correct size is confirmed. Blackwall keeps a more understated modern look, while raised white letter and redline create a stronger visual statement, so it helps to choose the style that matches the car’s wheel package and the overall look you want without compromising basic fitment.
What brands offer tires for the 2019 BMW 740i?
Tires for the 2019 BMW 740i are available from BFGoodrich, Nitto, and Pro-Trac across the supported radial sizes. Depending on the exact fitment, the available series include g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should come after the size and wheel setup are confirmed, since not every brand or series appears in every fitment. Once the correct size is established, compare the brands by the specific tire series offered, the sidewall treatments available in that size, and any stated rim-width or load details that affect your selection.
Restoration & Appearance
Which tire should I choose for a period-style 2019 BMW 740i?
A period-style approach on a 2019 BMW 740i starts with keeping the correct wheel diameter and the exact front-to-rear sizing layout already used on the car. Since this is a modern luxury-performance sedan with radial fitments only, the most relevant appearance choice is usually within the correct size rather than changing to an older construction style.
That often means deciding between a subdued blackwall look and a more expressive sidewall treatment such as redline or raised white letter where available. The cleaner and more conservative the presentation you want, the more important it becomes to match the tire’s visual character to the wheel package and overall stance of the car.
How does tire construction affect the appearance of a restored 2019 BMW 740i?
Tire construction is straightforward on the 2019 BMW 740i because every primary fitment here is radial. The visual difference comes less from bias-ply versus radial and more from profile, wheel diameter, and sidewall treatment, especially when comparing an 18-inch square setup to the 19-inch or 20-inch staggered arrangements.
For an appearance-focused project, the strongest effect usually comes from preserving the intended size relationship and choosing an appropriate sidewall style within that size. A blackwall tire keeps the look closer to contemporary luxury-sedan presentation, while redline or raised white letter options create a more custom visual statement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 BMW 740i?
Yes, modifications can affect tire fitment on a 2019 BMW 740i, especially when the car already has multiple factory-style size combinations across 18-inch, 19-inch, and 20-inch wheels. Changes to wheel width, offset, ride height, or suspension geometry can alter clearance at the fender, inner wheelhouse, and steering components.
That matters even more on staggered setups, where front and rear tires already differ in width and profile. Any time the car has aftermarket wheels or suspension changes, verify the actual tire size on each axle and inspect clearances at full steering lock and normal ride height before settling on a replacement tire.
What should I inspect before driving a 2019 BMW 740i on new tires?
Before driving a 2019 BMW 740i on new tires, check that the tire size matches the wheel diameter and axle position, then inspect inflation pressure, bead seating, and visible sidewall condition. It is also worth confirming that all four tires are installed in the intended locations on square or staggered setups.
A short visual inspection around the suspension and fender openings can prevent problems that are easy to miss in the shop. Listen for rubbing, watch for steering interference, and recheck pressure after the first few drives, particularly if the car has low annual mileage or any recent wheel, brake, or suspension work.
How often should tires on a 2019 BMW 740i be inspected?
Tires on a 2019 BMW 740i should be inspected regularly, even if the car is not driven daily. Check for uneven wear, cuts, bulges, cracking, and slow air loss, and pay close attention to the rear tires on staggered setups since they differ from the front in size and cannot be evaluated as a matching four-tire set.
A monthly walkaround is a sensible habit, with a more careful inspection before longer drives or seasonal use changes. Cars that spend long periods parked still age their tires, so condition matters just as much as tread depth, especially on a vehicle that combines heavier luxury-sedan weight with performance-oriented tire sizes.
